C-5 Measuring Resistance
Before measuring capacitance, remember it takes
time for zeroing when changing ranges. Floating
reading do not effect accuracy.
Caution
1) If
1
is shown on the LCD, which means the
Meter is overloaded, then set a higher measuring
range. If resistance is above 1M
Ω
, the reading
will only be steady after few seconds which is
normal for measuring high value of resistance.
2)
1
is displayed when no input(e.g. open circuit).
3) Make sure all objects, circuit and components
to be measured are without voltage and
discharge all high-voltage capacitors.
4) At 200M
Ω
range, test lead is short circuit, it has
1000 digits which need to be deducted from
the reading when making measurement. For
example, when measuring 100M
Ω
, it displays
110.00, 1000 digits need to be deducted (means
110.00-10.00=100.00M
Ω
).

1. Connect the black test lead to
COM
jack and
red test lead
Ω
jack.
2. Set rotary switch to
Ω
.
3. Connect the test leads across with the object
to be measured.

1) To avoid damage of the Meter or the equip-
ment under testing, disconnect circuit powers
and discharge capacitors before measuring
capacitance.
2) Connect capacitor to the capacitance jack.
