ASSEMBLY
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
battery door.
3. Insert two (2) AA bat-
teries, according to the
polarity marked in the
battery compartment
4. Close the battery door and tighten screw se-
curely.

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
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
AC mark is displayed.
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-
ment, keep the jaws fully closed to ensure
accurate measurements.
DC Current (Cat. No. 2237-20 only)
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.
OPERATION
1. Set the Rotary Dial to
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

Never make measurement on a circuit
in which voltage over AC600V exists.
Do not use with the Battery Cover removed.
