ASSEMBLY
To avoid an electrical hazard, turn
WARNING
the Rotary Dial to OFF and discon-
nect 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 bat-
tery door.
3. Insert two (2) AA batteries,
according to the polarity
marked in the battery com-
partment
4. Close the battery door and
tighten screw securely.
OPERATION
Only use MILWAUKEE test leads
WARNING
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 posi-
tion, the instrument is set to the correct measure-
ment mode, and the Data hold function is disabled.
Otherwise, 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
To avoid electrical shock:
DANGER
Never make measurement on a cir-
cuit in which voltage over AC600V exists. Clamp
tips are designed not to short the circuit under
test. If equipment under test has exposed con-
ductive 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
AC mark is displayed.
2. Press the jaw opening trigger to
open the jaws and clamp them onto
the conductor under test. The read-
ing 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.
Maximum conductor size is about

1.3" diameter. During measure-
ment, keep the jaws fully closed to ensure ac-
curate measurements.

2. With the jaws closed and without
clamping them around a conductor,
press the ZERO key to zero adjust
the display.
3. Press the jaw opening trigger to

around the conductor under test.
The reading is displayed.

wires at the same time. Irregular
results will occur.
4. Set the Rotary Dial to an appropriate position ac-
cording to current under test.
5. Press the ZERO key again to release the ZERO
function.
When current flows from the dis-

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 measure-
ments.
1. Set the Rotary Dial to
tion.
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.

ing the Hz Key toggles the
reading between AC Voltage
and Hz. NOTE: Hz Function
requires 70V or more.
Readings of frequency may fluctu-
