Parallel Connection
12V Battery
Meter setup to measure voltage:
• Set the rotary switch to the voltage ( or m ) setting. (The m setting is only for DC millivolt
measurements.)
• Press the “DC/AC” button to select AC or DC voltage measurement, the display will show the corresponding
symbol.
• Insert the black lead in the “COM” jack.
• Insert the red lead in the “ ” jack.
Connect:
Back probe to the negative (-) circuit or to ground.
Red probe to the circuit coming from the power source.
Resistance Measurements
Resistance is a static measurement which means that it must be measured with the power off. It is measured in
Ohms (Ω) and the values can vary greatly from a few milliohms (mΩ) for contact resistance to billions of ohms
for insulators.
WARNING
TURN OFF POWER AND DISCHARGE ALL CAPACITORS IN THE CIRCUIT TO BE TESTED BEFORE MAKING
IN-CIRCUIT RESISTANCE MEASUREMENTS. ACCURATE MEASUREMENT IS NOT POSSIBLE IF EXTERNAL
OR RESIDUAL VOLTAGE IS PRESENT.
NOTE: The resistance in the test probes can affect accuracy in the 400 range. Short the probes together and
press the “REL” button to subtract test lead resistance from the measurement.
