• Press to activate AutoHold. shows on the display.
• Press again or turn the rotary switch to resume normal operation.

MIN MAX AVG Recording Mode

The MIN MAX AVG mode records minimum and maximum input values. The Meter beeps and records a new value when the inputs go below the recorded minimum value, or above the recorded maximum value. This mode can be used to capture intermittent readings, record maximum readings while you are away or record readings while you are operating the equipment under test and cannot watch the Meter. MIN MAX AVG mode can also calculate an average of all readings taken since the MIN MAX AVG mode was activated.

The Meter tracks the minimum, maximum, and average values for each display which are updated 4 times per second.

To use MIN MAX AVG recording:

• To exit and erase stored readings, press for one second or turn the rotary switch.

Manual Ranging and Auto Ranging

The Meter has both Manual Range and Auto Range modes.

• In the Auto Range mode, the Meter selects the range with the best resolution.
• In the Manual Range mode, you override Auto Range and select the range yourself.

When you turn the Meter on, it defaults to Auto Range and Auto Range is shown.

1. To enter the Manual Range mode, press .Manual Range is shown.
2. In the Manual Range mode, press to increment the range. After the highest range, the Meter wraps to the lowest range.

Note
You cannot manually change the range in the MIN MAX AVG, or Display HOLD modes.

If you press while in MIN MAX AVG, or Display HOLD the Meter beeps twice, indicating an invalid operation and the range does not change.

3. To exit Manual Range, press for one second or turn the rotary switch. The Meter returns to Auto Range and Auto Range is shown.

AC Zero Input Behavior of True RMS Meters

True RMS Meters accurately measure distorted waveforms, but when the input leads are shorted together in the AC functions, the Meter displays a residual reading between 1 and 30 counts. When the test leads are open, the display readings may fluctuate due to interference. These offset readings are normal. They do not affect the Meter's ac measurement accuracy over the specified measurement ranges.

Unspecified input levels are:

• AC voltage: below 5% of 600 mV ac, or 30 mV ac.
• AC current: below 5% of 60 mA ac, or 3 mA ac.

VFD Low-Pass Filter (all 1587 Models)

The 1587 is equipped with an ac low-pass filter to measure the output of variable frequency motor drives (VFD). For ac voltage or ac frequency () measurements, press the blue button to activate the Low-Pass Filter function (). The Meter continues measuring in the selected ac mode, but now the signal diverts through a filter that blocks unwanted frequencies above 800 Hz. Refer to Figure 1. The low pass filter can improve measurement performance on composite sine waves that are typically generated by inverters and variable frequency motor drives.

To prevent possible electric shock or personal injury, do not use the VFD Low-Pass Filter function to verify the presence of hazardous voltages. Voltages that are greater than what is indicated may be present. First, make a voltage measurement without the filter to detect the possible presence of hazardous voltage. Then, select the filter function.

Note
When using the VFD Low-Pass filter function, the Meter goes to Manual mode. Select ranges by pressing the button. Autoranging is not available with the Low-Pass filter function.

Figure 1. VFD Low Pass Filter

Basic Measurements

The figures on the following pages show how to make basic measurements.

When connecting the test leads to the circuit or device, connect the common (COM) test lead before connecting the live lead; when removing the test leads, remove the live lead before removing the common test lead.

To prevent possible electrical shock, fire, or personal injury:

• Disconnect circuit power and discharge all high-voltage capacitors before you measure resistance, continuity, capacitance, or a diode junction.
• Remove circuit power before you connect the Product in the circuit when you measure current. Connect the Product in series with the circuit.

For better accuracy when measuring the dc offset of an ac voltage, measure the ac voltage first. Note the ac voltage range, then manually select a dc voltage range equal to or higher than the ac range. This procedure improves the accuracy of the dc measurement by ensuring that the input protection circuits are not activated.

AC and DC Voltage

Figure 2. Measuring AC and DC Voltage

Temperature (all 1587 Models)

The Meter measures the temperature of a type-K thermocouple (included). Choose between degrees Celsius (°C) or degrees Fahrenheit (°F).

1587 FC:
Press to toggle between °C or °F.

1587/1587T:
Press to toggle between °C or °F.

To prevent possible damage to the Meter or other equipment, remember that while the Meter is rated for -40 °C to 537 °C (-40 °F to 998.0 °F), the included K-type thermocouple is rated for 260 °C (500 °F). For temperatures out of that range, use a higher rated thermocouple.

To prevent risk of electric shock do not connect thermocouple to electrically live circuits.

Resistance

Figure 4. Measuring Resistance

Capacitance (all 1587 models)

Figure 5. Measuring Capacitance

Continuity

Figure 6. Testing for Continuity
The continuity test features a beeper that sounds as long as a circuit is complete. The beeper allows you to perform quick continuity tests without having to watch the display. To test for continuity, set up the Meter as shown in Figure 6. The beeper sounds when a short (<25 Ω) is detected.

To prevent possible damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high voltage capacitors before testing for continuity.

Diodes (all 1587 models)

Figure 7. Testing Diodes

AC or DC Current

To prevent personal injury or damage to the Meter:

• Never attempt to make an in-circuit current measurement when the open-circuit potential to earth is >1000 V.
• Check the Meter's fuses before testing. See Testing the Fuses later in this manual.
• Use the proper terminals, switch position, and range for your measurement.
• Never place the probes in parallel with a circuit or component when the leads are plugged into the current terminals.

Turn OFF power to the circuit under test, break circuit, insert Meter in series, and turn ON power. To measure ac or dc current, set up the Meter as shown in Figure 8.

Insulation

Insulation tests should only be performed on dead circuits. Check the fuse before testing. See Fuse Test later in this manual. To measure insulation resistance, set up the Meter as shown in Figure 9 and follow the steps below:

1. Insert test probes in the and nput terminals.

5. Push and hold to start the test. The secondary display shows the test voltage applied to the circuit under test. The high voltage symbol () along with a primary display showing the resistance in MΩ or GΩ appears. The icon appears on the lower portion of the display until is released. When resistance is higher than the maximum display range, the Meter displays the symbol and the maximum resistance for the range.
6. Keep the probes on the test points and release the button. The circuit under test then discharges through the Meter. The resistance reading remains on the primary display until a new test is started, a different function/range is selected, or >30 V is detected.

Figure 9. Testing Insulation

PI/DAR

Polarization Index (PI) is the ratio of the 10-minute insulation resistance to the 1 minute insulation resistance. Dielectric Absorption Ratio (DAR) is the ratio of the 1-minute insulation resistance to the 30 second insulation resistance.

Insulation tests should only be performed on de-energized circuits. To measure the polarization index or dielectric absorption ratio:

1. Insert test probes in the and input terminals.

Note
Because of the time required to perform the PI and DAR tests, use of test clips is recommended.

2. Press repeatedly to select the test voltage.
3. Press to select polarization index or dielectric absorption ratio.
4. Connect the probes to the circuit to be measured. The Tester automatically detects if the circuit is energized:

• The primary display shows ---- until you press the button and a valid resistance reading is obtained.
