1587/1577 Insulation Multimeters Introduction The Fluke Model 1587, and Model 1577 are battery-powered, true-RMS insulation multimeters (hereafter "the Meter") with a 6000-count and a 3 ¾ digit display. Although this manual describes the operation of both Models 1587 and 1577, all illustrations and examples assume use of Model 1587.
1587/1577 Users Manual Safety Information Use the Meter only as specified in this manual. Otherwise, the protection provided by the Meter may be impaired. See Table 1 for a list of symbols used on the Meter and in this manual. A XWWarning identifies hazardous conditions and actions that could cause bodily harm or death. A XWCaution identifies conditions and actions that could damage the Meter, the equipment under test, or cause permanent loss of data.
Insulation Multimeters Safety Information • • • • • • Remove test leads from the Meter before opening the Meter case or battery door. Never operate the Meter with the cover removed or the battery door open. Comply with local and national safety requirements when working in hazardous locations. Use proper protective equipment, as required by local or national authorities when working in hazardous areas. Avoid working alone. Use only the replacement fuse specified or the protection may be impaired.

Insulation Multimeters Rotary Switch Positions Table 2. Rotary Switch Selections Rotary Switch Positions Turn the Meter on by selecting any measurement function. The Meter presents a standard display for that function (range, measurement units, modifiers, etc.). Use the blue button to select any rotary switch alternate functions (labelled with blue letters). Rotary switch selections are shown in Figure 1 and described in Table 2. Switch Position B Measurement Function AC voltage from 30.0 mV to 1000 V.
1587/1577 Users Manual Table 2. Rotary Switch Selections (cont.) Switch Position Measurement Function X Continuity test. Beeper turns on at <25 Ω and turns off at >100 Ω. Buttons Use the buttons to activate features that augment the function selected with the rotary switch. The buttons are shown in Figure 2 and described in Table 3. O Diode test. There is no ranging in this (1587 only) function. Displays 0L above 6.600 V. c AC mA from 3.00 mA to 400 mA (600 mA overload for 2 minutes maximum).
Insulation Multimeters Buttons Table 3. Buttons Button Description Press to freeze the displayed value. Press again to release the display. When a reading changes, the display updates and the Meter beeps. h In MIN MAX AVG or Hz mode, this button operates a display hold. In Insulation Test mode, this schedules a test lock the next time you press t on the Meter or on the remote probe. The test lock acts to hold down the button until your press h or t again to release the lock.
1587/1577 Users Manual Understanding the Display Table 4. Display Indicators Display indicators are shown in Figure 3 and described in Table 4. Error messages that may appear on the display are described in Table 5. Indicator Description b Low battery. Indicates when it is time to replace the battery. When b is on, the backlight button is disabled to conserve battery life.
Insulation Multimeters Understanding the Display Table 4. Display Indicators (cont.) Indicator Description Z Unsafe voltage warning. Indicates 30 V or greater (ac or dc depending on the rotary switch position) is detected on the input. Also appears when the display shows 0L in the B, C, or E switch positions, and when batt appears on the display. The Z also appears when insulation test is active, or in Hz. a K (1587 only) “Smoothing” enabled.

Sleep mode is also disabled while the Meter is in a MIN MAX AVG Recording mode, AutoHold mode, and when performing an insulation test. Starts the Calibration mode. The Meter displays Cal and enters Calibration mode when the button is released. Disables the beeper.
1587/1577 Users Manual To use MIN MAX AVG recording: • Make sure the Meter is in the desired measurement function and range. (Autoranging is disabled in the MIN MAX AVG mode). • Press m to activate MIN MAX AVG mode. M appears on the display. • Press m to step through the high (MAX), low (MIN), average (AVG), and present readings. • 1. To enter the Manual Range mode, press r. Manual Range is displayed. 2. In the Manual Range mode, press r to increment the range.
Insulation Multimeters Understanding AC Zero Input Behavior of True RMS Meters Understanding 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.
1587/1577 Users Manual Making 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.

1587/1577 Users Manual Measuring Temperature (Model 1587) The Meter measures the temperature of a type-K thermocouple (included). Choose between degrees Celsius (°C) or degrees Fahrenheit (°F) by pressing r. LO HOLD MIN MAX TEST XWCaution To avoid 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).

1587/1577 Users Manual 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 10. The beeper sounds when a short (<25 Ω) is detected.

1587/1577 Users Manual Measuring AC or DC Current XWWarning To avoid 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.

1587/1577 Users Manual • Testing Insulation Insulation tests should only be performed on dead circuits. Check the fuse before testing. See Testing the Fuse later in this manual. To measure insulation resistance set up the Meter as shown in Figure 13 and follow the steps below: 1. Insert test probes in the p and q input terminals. 2. Turn the knob to INSULATION position. A battery load check is initiated when the switch is moved to this position.
Insulation Multimeters Making Basic Measurements Measuring Frequency (Model 1587) LO HOLD The Meter measures the frequency of a voltage or current signal by counting the number of times the signal crosses a threshold level each second. To measure frequency, set up the Meter as shown in Figure 14 and follow the steps below. MIN MAX 1. Connect the Meter to the signal source. 2. Turn the rotary switch to the B, C, or c position. 3. In the c position press the blue button to select dc if needed. 4.

Insulation Multimeters Cleaning Cleaning Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings. LO HOLD MIN MAX TEST Testing the Batteries To test the batteries, press h and turn to the rotary switch to the INSULATION position. This initiates a battery test and displays the charge level of the battery.
1587/1577 Users Manual Replacing the Batteries and Fuse Replace the fuse and batteries as shown in Figure 16. Follow the steps below to replace the batteries. XWWarning To avoid shock, injury, or damage to the Meter: • To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the battery indicator (b) appears. • Use ONLY fuses with the amperage, interrupt, voltage, and speed ratings specified. • 1.
