the AC line being measured. Ensure that
the jaws are completely closed and not
making contact with the AC line. For
maximum accuracy it is recommended that
the conductor passes through the centre of
the clamp head opening.
3-4 Apply power to the AC line being measured.
3-5 Read the displayed current.
3-6 If the displayed current is less than 200A,
set the range switch to the next lower range
position. For maximum accuracy select
the lowest range without overranging the
meter.
3-7 Remove power to the AC line and press the
trigger to open transformer jaws to remove
from the circuit.
4 RESISTANCE MEASUREMENT

circuit being tested when checking
resistance. Discharge any charged
capacitors. Never connect the probes to
any voltage while the selector is set to
Ω
OHM.
4-1 Plug the red test lead into the V
Ω
jack and
the black test lead into the COM jack.
4-2 Set the range switch to the desired
Ω
setting.
4-3 Attach the test leads to the circuit.
4-4 Read the displayed resistance.
5 CONTINUITY TEST
!
WARNING: Remove all power from
circuit being tested when checking
continuity. Discharge any charged
capacitors. Never connect the probes to
any voltage while the selector is set to
2K
.
5-1 Plug the red test lead into the V
Ω
jack and
the black test lead into the COM jack.
5-2 Set the range switch to the 2K
setting.
5-3 Attach the test leads to the circuit.
5-4 The buzzer will sound when the circuit has
less than 30
Ω
resistance and the measured
resistance value will be displayed.
MEASUREMENTS
Please take a few minutes to read these instruc-
tions and warnings on both sides prior to use.
1 DC VOLTAGE MEASUREMENT
!
WARNING: Maximum input is 600V DC.
1-1 Plug the red test lead into the V
Ω
jack and
the black test lead into the COM jack.
1-2 Set the range switch to the desired DCV
setting. It is best to start with the 600V range
if the voltage is not known.
1-3 Apply the test leads to the circuit to be
measured. Ensure that the black lead is
connected to the negative side of the circuit
and the red lead to the positive.
1-4 Read the displayed voltage.
1-5 If the minus (-) sign appears the voltage is
negative at the point being measured.
2 AC VOLTAGE MEASUREMENT
!
WARNING: Maximum input is 600V AC
(RMS).
2-1 Plug the red test lead into the V
Ω
jack and
the black test lead into the COM jack.
2-2 Set the range switch to the desired ACV
setting. It is best to start with the 600V range
if the voltage is not known.
2-3 Apply the test leads to the circuit to be
measured.
2-4 Read the displayed voltage.
3 AC CURRENT MEASUREMENT
!
WARNING: Do not break or open the AC
line being measured. When measuring
AC current this unit is designed to clamp
around one of the AC lines. Do not leave
clamped for more than 60 seconds. Do
not attempt to measure current using
the test leads.
3-1 Turn off power to AC line being measured.
3-2 Set the range switch to the 600A ACA
current setting.
3-3 Press the trigger to open clamp jaws and
close around one insulated conductor of
