Capacitance Measurements

WARNING

:  To  avoid  electric  shock,  disconnect  power  to  the  unit 

under test and discharge all capacitors before taking any capacitance 
measurements. Remove the batteries and unplug the line cords.

1. Set the rotary function switch to the cap position.
2. Insert the black test lead banana plug into the negative (COM) jack.

Insert the red test lead banana plug into the positive (V)  jack.

3. Touch the test leads to the capacitor to be tested.
4. Read the capacitance value in the display.

Frequency or % duty cycle measurements

1. Set the rotary function switch to the “VDC/AC,Hz/%” position.
2. Insert the black lead banana plug into the negative COM jack and the 

red test lead banana plug into the positive V jack.

3. Select Hz or % duty with the 

Hz/%

 button.

4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.

Temperature Measurements

WARNING: 

To avoid electric shock, disconnect both test probes from 

any source of voltage before making a temperature measurement.

1. Set the function switch to TEMP.
2. Insert the Temperature Probe into the negative (COM) and the V jacks, 

making sure to observe the correct polarity.

3. Select °C or °F with the MODE button.
4. Touch the Temperature Probe head to the part whose temperature you 

wish to measure. Keep the probe touching the part under test until the 
reading stabilizes (about 30 seconds).

5. Read the temperature in the display. The digital reading will indicate the 

proper decimal point and value.

WARNING:

 To avoid electric shock, be sure the thermocouple has 

been removed before changing to another measurement function.
