    The SureStart feature briefly reports its findings in four groups of information. These are:  Identify System – after analyzing all the voltage and current inputs, PowerSight identifies what type of system is connected.  Error Summary – after analyzing connections, the number of possible errors detected is displayed, appearing for one second, each 6 seconds.

    The bottom line of the display tells the specific voltage type of the general system that has been detected. For instance, a typical display is “277 / 480 V (p-n, p-p)”. This means the nominal voltages present are 277 Vrms phase-neutral and 480 Vrms phase-phase.

  • Page 91: Measurement Modes

    Measurement Modes Introducing Measurement Modes PowerSight performs so many measurements that it is quite a challenge to keep the instrument easy to use. Often, you make measurements on one general type of system. There is no need to complicate your task by PowerSight asking you to make the same choices over and over.
  • Page 92 Wye systems are usually measured using phase-neutral voltages. Delta systems are usually measured using phase-phase voltages. On occasion, you may wish to measure phase-phase voltages in a wye system if the equipment that you are monitoring bridges two hot voltages (like a single- phase air conditioner running at 240 V). In a perfectly balanced three-phase system, the phase-neutral voltage is equal to the phase-phase voltage divided by the square root of 3 (Vpn=Vpp/1.732).

    The variable frequency measurement mode provides accurate true RMS readings of voltage, current, and power for input frequencies varying from 22 to 200 Hz or from 360 to 440 Hz. If even one voltage or current input is in this frequency range, PowerSight can also measure the true RMS of DC and rectified signals that are also connected while in this measurement mode.

It displays the instantaneous levels of voltage and current as they continually vary, as you see on an oscilloscope. All other measurements are derived from them.

Therefore it does not limit the size of your logs or write over any other type of data. Whenever you store a waveform set in PowerSight it writes over the oldest waveform set that is stored in the meter.

    Setting the Data Logging Period One of the most important settings is the choice of logging period. This is the length of time between the creation of data records. 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.
