5.6. Capacitance Measurements

WARNING: To avoid electric shock, discharge the capacitor under test

before measuring.

Set the function switch to the Ω

lnsert the black test lead banana plug into the negative COM jack and

the red test lead banana plug into the V Ω

Use the MODE button to select CAP Measurements.

Touch the test probe tips across the part under test.

Read the capacitance value in the display.

The display will indicate the proper decimal point and value.

For very large values of capacitance measurement it can take several

minutes before the final reading stabilizes.

1. lnsert the black test lead banana plug into the negative COM jack and

the red test lead banana plug into the V Ω

2. Turn the function switch to Ω

button to select the diode function if necessary (diode symbol will

appear on the LCD when in Diode test mode).

3. Touch the test probe tips to the diode or semiconductor junction under

test. Note the meter reading.

4. Reverse the test lead polarity by reversing the red and black leads.

Note this reading.

5. The diode or junction can be evaluated as follows:

•

If one reading displays a value (typically 0.400V to 0.900V) and the

other reading displays "0L" ,the diode is good.

•

If both readings display "0L" the device is open.

•

If both readings are very small or "0", the device is shorted.

The NCV function works on any rotary switch position.

1. Test the detector on a known live circuit before use.

2. Hold the top of the meter very close to the voltage source as shown.

3. If voltage is present. the red light will long lighting.

NOTE: Do not touch the top of the meter when using this function.

NOTE: Test on known live circuit before using.
