Triplett CM200 - Operation: Diode and NCV Measurements; Diode Measurements; Non-Contact Voltage (NCV) Measurements

4. Touch the test probe tips across the part under test.
5. Read the capacitance value in the display.
6. 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.
Diode Measurements
1. Insert the black test lead banana plug into the negative COM jack and the red
test lead banana plug into the V Ω CAP positive jack
2. Turn the function switch to Ω CAP position. Use the MODE 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 “OL”, the diode is good.
• If both readings display “OL” the device is open.
• If both readings are very small or “0”, the device is shorted.
Non-Contact Voltage (NCV) Measurements
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.
