Introduction

The Fluke 1587 FC, 1587, 1587T, and 1577 are battery-powered, true-RMS insulation multimeters (the Product or Meter) with a 6000-count display. Although this manual describes the operation of all models, all illustrations and examples assume use of Model 1587 FC.
The Meter measures or tests:
• AC / DC voltage and current
• Resistance
• Continuity
• Insulation resistance
• Voltage and current frequency
• Diodes (all 1587 models)
• Temperature (all 1587 models)
• Capacitance (all 1587 models)
The 1587 FC supports the Fluke Connect™ Wireless System (may not be available in all regions). Fluke Connect™ is a system that wirelessly connects your Meter with an app on your smartphone or tablet. The app shows the Meter measurement on your smartphone or tablet screen. You can save these measurements with Fluke Connect™ to share with your team.
More information about how to use Fluke Connect is on page 30.

AutoHold Mode

Warning
To prevent electrical shock, do not use the Display AutoHold mode to determine if a circuit is live. Unstable or noisy readings will not be captured.
In the AutoHold mode, the Meter holds the reading on the
www.GlobalTestSupply.com
display until it detects a new stable reading. Then the Meter beeps and displays the new reading.
• Press  to activate AutoHold. Y 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:
• 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 shows on the display.
• Press m to step through the high (MAX), low (MIN), average (AVG), and present readings.
• To pause MIN MAX AVG recording without erasing stored values, press . S shows on the display.
• To resume MIN MAX AVG recording, press again. S turns off.
• To exit and erase stored readings, press m for one second or turn the rotary switch.

Manual Ranging and Auto Ranging
www.GlobalTestSupply.com

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 r. Manual Range is shown.
2. In the Manual Range mode, press r 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 r 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 r 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 (B) measurements, press the blue button to activate the Low-Pass Filter function (K). 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.
