Capacitance Measurement; Frequency Measurement; Temperature Measurement - RIDGID micro DM-100 Manual

Capacitance Measurement

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

To reduce the risk of electric shock, disconnect both test probes from any
WARNING
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.
To reduce risk of electric shock, be
WARNING
sure the thermocouple has been removed before
changing to another measurement function.
