3 RESISTANCE MEASUREMENT
WARNING: Remove all power from the circuit being
tested when checking resistance. Discharge any charged
capacitors. Never connect the probes to any voltage
while the selector is set to OHM.
3-1 Plug the red test lead into the V jack and the black test
lead into the COM jack.
3-2 Set the range switch to the desired Ω position. If the
resistance is not known, set the switch to highest range
and reduce until a satisfactory reading is obtained.
3-3 Attach the test leads to the circuit.
3-4 Read the displayed resistance.
NOTE: For measurements > 1M Ω the meter may take a
few seconds to stabilize reading. This is normal for
high resistance measurements. When input is not
connected, i.e. open circuit, "1" will be displayed to
indicate over range.
4 DC CURRENT MEASUREMENT
WARNING: Remove all power from the circuit being
tested when checking current. When using 10A scale,
do not connect to circuit for more than 10 seconds.
4-1 Plug the red test lead into the mA jack and the black test
lead into the COM jack if the current to be measured is
less than 200mA. Insert the red test lead into the 10A
jack if current being measured is between 200mA and
10A.
