Page 11: Current Probes
Probes such as the HA1000 are excellent choices to use with PowerSight because they support all the accuracy specifications of the product. For instance, the HA1000 has an accuracy of 0.5% whereas many probes on the market have an accuracy of 2- 3%.
Page 12 The HA100 probe is the same compact size as the HA5. The HA100 measures from 0.1 to 100 amps at 2% accuracy. It is a good choice over the HA1000 if you wish to lock PowerSight, its leads, and current probes inside a power panel that you are monitoring.

Any dirt or rust will affect the accuracy of the measurements! Connections to PowerSight Voltage test leads plug into the top end of PowerSight. Each test lead of the Deluxe Voltage Test Lead set is labeled (V , or...
Page 14 Current probes plug into the top end of PowerSight, just above the voltage inputs. Each current probe is labeled (I , or I ) and each jack is similarly labeled (I , or I ). When plugging a current probe into PowerSight, the flat side of the plug should be facing upwards so the label is readable.
Page 15: Introduction To Power Delivery Configurations
Introduction to Power Delivery Configurations Figure 1 presents most common power delivery configurations. PowerSight is able to measure voltage, current, power, power factor, and more for all of these systems. Figure 1A presents the normal single- phase and split-phase service as found in a residential service.
Page 16 Connections to an Open Delta Circuit (2PT/3CT)figure Although phase-to-phase is the normal voltage measurement mode for this service, PowerSight can be set to phase-to-neutral (even though the neutral is not connected). In this case, the measured voltages will be phase-to-metering-neutral (such as V = 277V for a 480V service) and all other measurements will also be correct.

1 power and phase 1 power factor. Caution: Until you are certain that your voltage connections to PowerSight are correct, disconnect any current probes. This is because PowerSight and all of its connections float at the potential of V . If V is "hot", there may be a breakdown through the insulation of any attached probes.
Page 18: Connecting To 120 V Outlet Adapter Box
PowerSight are as shown in figure 2, V will be some relatively large number like 120 volts and V will be a small voltage like 3 volts. If you then reverse the ground and neutral leads, V will now read slightly less, like 117 volts. If "hot" and "neutral"...

Note: The 120ADPa is rated for continuous duty of up to 15 Arms. Do not exceed this continuous load. To evaluate the power usage of an appliance, simply plug the appliance into the top of the 120 V Outlet Adapter Box after the other connections have been made and verified.
Page 20: Connecting To Split-Phase (Two Phase) Power
In this configuration, the voltage, current, and power of each load can be displayed directly or graphed on your PC using our PSM software.

It also provides 208V. Depending on what you intend to monitor, it may be appropriate to set PowerSight in phase-phase voltage measurement mode (to monitor three-phase loads or to look at total power) or in phase-neutral voltage measurement mode (to monitor single phase loads).
Page 24: Connections Using 2 Current Approach
A necessary use for this type of connection is to measure utility power where only two metering CTs and three PTs are provided. After hooking up to the CTs and PTs, you enter the input ratios into PowerSight (see the Setting Input Ratios section) in order to record the correct values (the values on the primary side of the transformers).
Page 25: Connections To A 3 Ct / 3 Pt Metering Circuit
Connections To a 3 CT / 3 PT Metering Circuit Sometimes it is helpful to monitor a load indirectly, by connecting PowerSight to a metering circuit in front of the load. A few circumstances where this is the case are: ...
Page 26  the voltage delivered to the load exceeds the 600Vrms rating of PowerSight and you do not have other high voltage probes. A typical metering circuit showing PowerSight connected is shown in figure 9. This circuit has three CTs and,...
Page 27 This in turn allows accurate power and cost readings without having to multiply the results times some ratio. Remember that these ratios are reset to 1:1 whenever PowerSight is turned off. Similarly, the PTs take a primary voltage and step it down to a secondary value.
Page 28: Connections To A 2 Ct / 2 Pt Metering Circuit
If you clamp onto the CTs, rather than clamping onto each of the primary currents directly, PowerSight must be operating in the 2 Current Probe mode of operation (see the Phase-Neutral vs Phase-Phase vs 2 Current Mode section). Connections To an Open Delta (3CT / 2PT) Metering Circuit In the open delta configuration, two PTs and 3 CTs are available.

If you use this method, set the input ratio for the current probe to 1 : 2 (see the Changing Input Ratios in PowerSight section). If the current to be measured is small, it may be acceptable to...
Page 34: Turning Powersight On
If you wish to operate PowerSight without being tethered to a power outlet, the Line-to-DC converter accessory (order LDC4) offers the ability to power a PS4500 (or any model except the PS3000) directly off the line voltage being monitored. It works with 50 Hz and 60 Hz power, operating off 100 to 480 Vrms input, single-phase or three-phase.
Page 35: Turning Powersight On
Turning PowerSight Off To turn PowerSight off, simply press the green on/off button at the lower right of the keypad on the front panel. This provides a graceful software/firmware shutdown. If pressing the button briefly does not turn the meter off, press the on/off button down and hold it down for 3 seconds to force a hardware shutdown.

Page 54: Measurement Types
Measurement Types Voltage Measurements Voltage is the difference in electromotive potential between two points. Simply stated, it is the force that generates current flow and to measure voltage, two points of connection are required. In AC circuits, this force, measured in volts, usually varies continuously and always reverses direction.

Page 59: Current Measurements
Current Measurements Current is the flow of charged particles, usually electrons, through a point. Current is measured in units of amps (which is short for amperes) and its symbol is commonly “I”. In AC circuits, current often varies continuously and always reverses direction. In DC circuits, it is usually steady and never reverses direction.
Page 60: Current Measurements In Powersight
For the PS4500, the RMS of every full cycle is measured, so these numbers are exact. In the PS4500, the present current is the summary of the RMS current over one second. It is the average of the RMS currents of every cycle during the most recent second.
Page 61 Note that if PowerSight is not monitoring consumption, the maximum, minimum, and average values are the results from the last monitoring session. Note that when PowerSight is operating in 2 current mode, I not measured or displayed.
Page 62: Current Measurements In Psm
When measuring DC current, the RMS value is the same as the DC value. To set PowerSight for reading DC currents, refer to the section on Setting Measurement Modes. Remember that you need to have a DC current probe in order to read DC current.

This value is useful for deciding how much capacitance to add to a circuit to bring current into phase with voltage, thereby raising the displacement power factor. Displacement power factor is 1.00 for a purely resistive load or a DC system and drops down as the reactive power increases.
Page 70: True Power Factor Measurements In Powersight
True Power Factor Measurements in PowerSight The PS4500 performs all commonly desired true power factor measurements. To view true power factor, press [Power Factor]. If the display says “True P.F.”, then pressing [Power Factor] repeatedly will allow you to view the true power factors of phases 1, 2, and 3 and the total power factor of the three phases.
Page 71 ), [Power Factor] (to display PF ), [More...] (to display maximum PF ), [More...] (to display minimum PF ), and then [More...] (to display average PF In this way, by combining the [Power Factor] and [More...] keys, there are 16 true power factor measurements available. The display of true power factor gives an indication if current may be leading or lagging voltage.

When monitoring consumption, the actual energy consumed is displayed by pressing [Energy]. Based on the history of consumption, estimates of energy use per hour, energy use per month, and energy use per year are calculated each second.
Page 76: Energy Measurements In Psm
The cost of energy consumed is defined as the product of the × energy consumed times the user-defined rate: $= KWH rate PowerSight presently uses a simple single rate price system. Useful measurements and estimates of cost are:  Cost of energy consumed (elapsed cost) ...
Page 77: Cost Measurements In Powersight
10 minutes of monitoring and the rate is $0.10/KWH, then the cost during the monitoring session is $0.50. The PS4500 calculates cost each second, using every cycle for exact measurements. The estimated cost per hour is the elapsed cost, divided by the hours of monitoring.
Page 78: Cost Measurements In Psm
In this way, by combining the [Cost] and [More...] keys, there are 4 cost measurements available. The rate used by PowerSight to estimate cost can be displayed or changed by the user at any time. It is one of the setup functions that can be accessed through the [Setup] key.
Page 79: Demand Period Measurements
Peak demand  Peak demand period. Demand Period Measurements in PowerSight During monitoring of energy consumption, the peak demand period is constantly updated. The logging interval is used as the demand period, so if the logging period is set to 15 minutes, the demand periods will also be 15-minute periods.
Page 80: Frequency Measurements
The average frequency is the average frequency of all the cycles during the time of interest. When operating in the variable frequency modes, the PS4500 determines the fundamental frequency of every cycle. The bands of frequencies that it can measure are from 22 to 220 Hz and from 360 to 440 Hz.

The measurements of frequency presented on the PS4500 can also be displayed in PSM by using the remote control feature. In addition, our Report Generator software will present maximum, minimum, and average frequency during any one or two intervals of time set by the user. If two time intervals are chosen, it will report the percent change and the actual change between the two intervals.

PowerSight can also measure the true RMS of DC and rectified signals that are also connected while in this measurement mode. It is generally recommended that you operate in one of the fixed frequency modes whenever you can. One reason is that there is the potential of slight errors in measuring the frequency of certain waveforms.

This has no effect on the measurement rate or the sampling rate. Unlike inexpensive data loggers that only take measurements when a record is created, PowerSight measures all its variables every second, regardless of the recording rate. This is very important when logging power, since loads typically vary greatly and quickly.

Page 136: Monitoring High-Speed Transient Events
Monitoring High-Speed Transient Events Introduction The three general areas of power quality analysis are in investigating on-going harmonic content, analyzing temporary changes in RMS voltage and current levels, and in analyzing instantaneous high-speed (non-RMS) voltage and current transients. High-speed transients are voltages or currents unrelated to the fundamental frequency of the power being used.

Page 162: Working With Graphs And Waveforms
Working with Graphs and Waveforms General It is important to us to allow you to work with and manipulate the various graphs and waveform presentations in PSM. We try to make the features that accomplish this look and feel the same throughout the program so you can handle all waveforms and graphs in the same way as much as possible.
Page 163 Often, the presentation of a graph can be enhanced by changing the title at the top from the filename to something more descriptive. This does not change the filename, but it may improve the look of the graph. Also, points of interest can be brought out in a presentation by adding labels to the chart.
Page 164: Reading Graphs And Waveforms
Whatever is displayed can be printed by clicking on “File” and then “Print”. It can also be saved as a Windows bitmap file by clicking on “File” and then “Save as BMP”. A very handy feature is the “Redo” icon. Whenever it is visible, clicking on it give you fresh data to look at.

First, check that you have all the voltage and current leads connected correctly. Then if that doesn't solve your problem, check that the frequency mode of the PowerSight is in the correct mode for your situation. 5. Why doesn't my PowerSight turn on? This is most likely caused by a dead battery.
Page 170 A fully charged PS4500 will run 10-12 hours. The PS4500 displays the charge of the battery and the estimated time of charge when you press the [Setup] button. The PS4500 is fully charged in about 3-4 hours. The battery should not need replacement for at least 2 years.
Page 171 PowerSight? Unfortunately, no. Only current probes made by Summit Technology can be used with the PowerSight Products. This is because all of our probes are "self-identifying". This means the user does not have to use an input ratio to use the probes. If there is a special need to use a certain probe, let us know at support@SummitTechnology.com.
Page 172 14. Why won't my PS4500 run on an LDC (line-to-DC converter) for more than 6-8 hours? You may be using the wrong LDC. The PS4500 only works with the LDC4 model. It can supply up to 500ma. 15. How do I measure a large load carried by 2 or more parallel conductors? There are two approaches you can use.
