Capacitance Measurement

 WARNING

 To reduce risk of electric shock, disconnect all power (remove batteries, 

unplug cord, discharge all capacitors, etc.) to the circuit being measured before taking any 

capacitance measurement. Use the DC Voltage function to confirm that the capacitor is 

discharged.
  1.  Set the function switch to CAP position. (“nF” and a small value will appear in the dis-

play). 

  2.  Insert the black test lead plug into the “COM” terminal and the red test lead plug into 

the “CAP”  terminal.

  3.  Touch the test leads to the capacitor to be tested. The display will indicate the value, 

proper decimal point and symbol.

Frequency Measurement

  1.  Set the function switch to Hz% position.
  2.  Insert the black test lead plug into the “COM” terminal and the red test lead plug into 

the “F”  terminal.

  3.  Touch the test probe tips to the circuit under test.
  4.  Read the frequency in the display. The digital reading will indicate the value, proper 

decimal point and symbols (Hz, kHz).

Temperature Measurement

 WARNING

 To reduce the risk of electric shock, disconnect both test probes from any 

source of voltage before making a temperature measurement.
  1.  If you wish to measure temperature in °F, set the function switch to °F range. If you 

wish to measure temperature in °C, set the function switch to °C range.

  2.  Insert the temperature adapter in “COM” and “V Ω CAP TEMP Hz” terminal with  

–ve side in “COM” and +ve side in “V Ω CAP TEMP Hz” terminal.

  3.  Insert the Temperature Probe into the adapter.
   4.  Touch the Temperature Probe head to the part 

whose temperature is to be measured. Keep 

the probe in contact with the part under test 

until the reading stabilizes (about 30 seconds).

  5.  Read the temperature in the display. The digi-

tal reading will indicate the proper value with 

decimal point.

 WARNING

 To reduce risk of electric shock, be 

sure the thermocouple has been removed before 

changing to another measurement function.
