WARNING

Only use MILWAUKEE test leads with the MILWAUKEE Clamp Meters.

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 Data hold function is disabled. Oth- erwise, desired measurement cannot be made.

LCD Backlight

The LCD backlight will turn off after about 3 minutes of inactivity. Push any button or turn the rotary dial to turn the backlight on.

Making a Measurement

AC Current

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over AC600V exists. Clamp

tips are designed not to short the circuit under

1. Set the Rotary Dial to position. DC mark is displayed.

2. With the jaws closed and without clamping them around a conduc- tor, press the ZERO key to zero adjust the display. 3. Press the jaw opening trigger 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. 4. Set the Rotary Dial to an appro-

priate position according to current under test.

5.Press the ZERO key again to release the ZERO function.

CAUTION When current flows from the display side to the underside of the meter, the polarity is positive; flow from

underside to display side, the polarity is negative.

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 displayed.

AC Voltage

DANGER To avoid electrical shock: Never make measurement on a circuit

in which voltage over AC600V exists.

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

Risk of electric shock

Indicates that this instrument can clamp on bare conductors when mea- suring a voltage corresponding to the applicable measurement category, which is marked next to this symbol.

WARNING

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

Loading/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

2. Press the jaw opening trigger to open the jaws and clamp them onto the conductor under test. The reading is displayed.

Cat. No. 2237-20 only: Pressing the “Hz” Key toggles the reading between AC Current and Hz. NOTE: Hz Function requires 50A or more.

NOTE: Do not clamp over 2 or more wires at the same time. Irregular results will occur.

CAUTION Maximum conductor size is about 1.3" diameter. During measure-
