ASSEMBLY

WARNING

To avoid an electrical hazard, turn the rotary dial to OFF and disconnect the test leads before replacing batteries.

Changing the Batteries

Replace batteries when the low battery indicator is displayed.

1.Turn rotary dial to OFF and disconnect the test leads.

2.Unscrew and remove battery door.

3.Insert two (2) AAA batteries, according to the

polarity marked in
the battery com-
partment
4. Close the battery
door and tighten	1.5V
	1.5V

screw securely.

OPERATION

WARNING

Only use MILWAUKEE test leads with the MILWAUKEE Clamp Meter.

Inspect test leads before each use. Use Clamp Meter to run a continuity test.

Before Use

Confirm the rotary dial is set to the correct position, the instrument is set to the correct measurement mode, and the hold function is disabled. Otherwise, desired measurement cannot be made.

LCD Backlight

The LCD backlight will turn off after about 10 min- utes of inactivity. Push the backlight button to turn the backlight on or off.

Making a Measurement

AC Current

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over 600 volts AC exists. Clamp tips are designed not to short the circuit under test. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting.

Do not use with the battery cover removed. Disconnect the test leads from the instrument for current measurement.

1. Set the rotary dial to

position. AC mark is dis-
played.
2. Press the jaw opening trig-	200A
ger to open the jaws and
clamp them around the
conductor under test. The
reading is displayed.
NOTE: Do not clamp over 2
or more wires at the same
time. Irregular results will
occur.

CAUTION Maximum conductor size is 1" diameter. During measurement, keep the jaws fully closed to ensure accurate

measurements.

AC Voltage

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over 600 volts AC exists.

Do not use with the battery cover removed. Keep fingers away from jaws during mea- surements.

1. Set the rotary dial to position. 2. Connect the red test lead to the VΩ terminal and the black test lead to the COM terminal. 3. Connect the test leads to the circuit under test. The reading is displayed.

DC Voltage

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over 600 volts DC exists.

Do not use with the battery cover removed. Keep fingers away from jaws during mea- surements.

1.Set the rotary dial to position.

2.Connect the red test lead to the VΩ terminal and the black test lead to the COM terminal.

3.Connect the red test lead to the positive (+) side and black test lead to the negative (-) side of the circuit under test. The reading is displayed. A reversed connection is indicated as a negative value.

Resistance/Continuity Measurements

DANGER

To reduce the risk of electric shock for Resistance and Continuity measurements, never use the meter on an energized circuit. If testing a capacitor, make sure it is fully discharged before touching or attempting to make a measurement.

Do not use with the battery cover removed.

Resistance

1. Set the rotary dial to posi- tion.

2. Connect the red test lead to the VΩ terminal and the black test lead to the COM terminal.

Confirm “OL” is indicated on the display, and then touch the tips of the test leads to- gether to short circuit them to confirm the zero indication.

3.Connect the test leads to both ends of the resistor under test. The reading is displayed.

CAUTION

After shorting the test leads, the displayed value may not be zero due to the resistance of test leads themselves.

Continuity

1. Set the rotary dial to posi- tion.

2. Connect the red test lead to the VΩ terminal and the black test lead to the COM terminal.

Confirm “OL” is indicated on the display, and then touch the tips of the test leads to- gether to short circuit them to confirm the zero indica- tion. A buzzer will sound.

3.Connect the test leads to

both ends of the conductor under test. If the resistance under test is 30 Ω or less, the buzzer will sound.
