OPERATING INSTRUCTIONS
DC CURRENT LESS THAN 200mA
1. For mA DC currents less than 200mA, insert RED test lead into VΩ
jack
5
, and BLACK test lead into COM jack
4
, and rotate Function
Selector Switch
2
to the highest mA DC setting (200mA).
2. To measure current: Remove power from circuit, open circuit at
measurement point, connect meter in-series in the circuit using
the test leads, and apply power to circuit.
NOTE:
If measuring mA, the Function Selector Switch
2
may
be rotated to successively lower mA DC settings to obtain higher
resolution measurements.

Do not attempt to measure more than 10A.
When measuring currents greater than 6A, a measurement
time of 30 seconds followed by 10 minutes of recovery time
is recommended.
RESISTANCE MEASUREMENTS
1. Insert RED test lead into VΩ jack
5
, and BLACK test lead into
COM jack
4
, and rotate Function Selector Switch
2
to the
highest Ω setting (2MΩ).
2. Remove power from circuit.
3. Measure resistance by connecting test leads to circuit and
rotating the Function Selector Switch
2
to successively
lower Ω settings to obtain higher resolution measurements.
NOTE:
When in a Resistance setting and the test leads are open
(not connected across a resistor), or when a failed resistor is under
test, the display will indicate O.L. This is normal.
DO NOT attempt to measure resistance on a live circuit.
