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 1MΩ, 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 200MΩ 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 100MΩ, it displays

110.00, 1000 digits need to be deducted (means

110.00-10.00=100.00MΩ).

“ ”

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.
