4. MEASURING PROCEDURE
4-1 ACV measurement procedure
1)Rotate the function switch to the " ACV " position and
Power ON the meter.
2)Connect Red test lead to the " V Ω" input terminal and
Black test lead to " COM " input terminal.
3)Use the test lead measurement unknown AC voltage.
4)Read the Display. The show value will correspond to the
position selected. If the Display shows " ---- ", it
indicates an out-of-range measurement.
4-2 DCV measurement procedure
1)Rotate the function switch to the " DCV " position and
Power ON the meter.
2)Connect Red test lead to the " V Ω" input terminal and
Black test lead to " COM " input terminal .
3)Use the test lead measurement unknown DC voltage.
4)Read the display . The show value will correspond to the
position selected. If the Display shows " ---- " it
indicates an out-of-range measurement.
Remark :
* Observe polarity when measuring DC voltage.
4-3 Resistance measurement procedure
1)Rotate the function switch to the Ωposition and Power
ON the meter.
2)Connect red test lead to the " V Ω" input terminal and
black test lead to " COM " input terminal .
Connect test lead to the resistance.
