Insulation Multimeters

Introduction

The Fluke Models 1587,1587T, and 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

all models, all illustrations and examples assume use of

Model 1587.

These meters meet CAT III and CAT IV IEC 61010

standards. The IEC 61010 standard defines four

measurement categories (CAT I to IV) based on the

magnitude of danger from transient impulses. CAT III

meters are designed to protect against transients in Fixed

equipment installations at the distribution level; CAT IV

meters are designed to protect against transients from the

primary supply level (overhead or underground utility

service).

The Meter measures or tests the following:

• AC / DC voltage and

current • Diodes (Model 1587)

• Resistance • Continuity

• Voltage and current

frequency • Capacitance (Model

1587)

• Temperature (Model

1587) • Insulation testing

Unsafe Voltage

To alert you to the presence of a potentially hazardous

voltage, when the Meter detects a voltage ≥ 30 V or a

voltage overload (OL), the Z symbol is displayed.

Test Lead Alert

To remind you to check that the test leads are in the

correct terminals, LEAd is momentarily displayed when you

move the rotary switch to or from the c position.

XW Warning

To avoid a blown fuse, damage to the Meter,

or serious personal injury, never attempt to

make a measurement with a test lead in an

incorrect terminal.

Battery Saver (Sleep Mode)

The Meter enters the “Sleep mode” and blanks the display

if there is no function change or button press for

20 minutes. This done to conserve battery power. The

Meter comes out of Sleep mode when a key is pressed or

when the rotary switched is turned.

To disable the Sleep mode, hold down the blue button

while turning the Meter on. Sleep mode is always disabled

in the MIN MAX AVG recording mode, AutoHold mode,

insulation test active, or if the auto power off feature has

been disabled by pressing the blue button when the Meter

is turned on.

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. 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.

Low-Pass Filter (Model 1587 and 1587T)

The 1587 is equipped with an ac low-pass filter. When

measuring ac voltage or ac frequency (B), 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 5. The low

pass filter can improve measurement performance on

composite sine waves that are typically generated by

inverters and variable frequency motor drives.

XWWarning

To avoid possible electric shock or personal

injury, do not use the Low-Pass Filter

function to verify the presence of hazardous

voltages. Voltages 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 Low-Pass filter function, the

Meter goes to Manual mode. Select ranges by

pressing the r button. Autoranging is not

available with the Low-Pass filter function.

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.

XWWarning

To avoid electric shock, injury, or damage to

the Meter, disconnect circuit power and

discharge all high-voltage capacitors before

testing resistance, continuity, diodes, or

capacitance.

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.

Measuring Temperature (Model 1587 and 1587T)

The Meter measures the temperature of a type-K

thermocouple (included). Choose between degrees

Celsius (°C) or degrees Fahrenheit (°F) by

pressing r.

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). For temperatures out

of that range, use a higher rated

thermocouple.

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.

XWCaution

To avoid possible damage to the Meter or to

the equipment under test, disconnect circuit

power and discharge all high voltage

capacitors before testing for continuity.

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.

Turn power OFF to the circuit under test, break circuit,

insert Meter in series, turn power ON. To measure ac or

dc current, set up the Meter as shown in Figure 12.

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. If the battery fails the test b and bat

appear in the lower display. Insulation tests cannot

be performed until the batteries are replaced.

3. Press r to select the voltage.

4. Connect the probes to the circuit to be measured.

The Meter automatically detects if the circuit is

energized.

• The primary display shows - - - - until you press

t and a valid insulation resistance reading

is obtained.

• The high voltage symbol (Z) along with a primary

display of >30 V warns if voltage more than 30 V

ac or dc is present. In this condition, the test is

inhibited. Disconnect the Meter and remove

power before proceeding.

5. Push and hold t to start the test. The

secondary display shows the test voltage applied to

the circuit under test. The high voltage symbol (Z)

along with a primary display showing the resistance

in MΩ or GΩ appears. The T icon appears on the

lower portion of the display until t is released.

When resistance is higher than the maximum display

range, the Meter displays the Q symbol and the

maximum resistance for the range.

6. Keep the probes on the test points and release the

t button. The circuit under test then discharges

through the Meter. The resistance reading appears

on the primary display until a new test is started or a

different function or range is selected or > 30 V is

detected.

a threshold level each second. To measure frequency,

set up the Meter as shown in Figure 14 and follow the

steps below.

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. Press the f button.

5. Press the blue button, the f button, or change the

rotary switch position to end this function
