6-7. Measuring Capacitance
Follow these steps to measure capacitance normal:
1. Discharge each capacitor before testing by shorting its leads together.
Use caution when handling some capacitors, as they can be charged
with considerable electricity.
Caution: If you attempt to measure the capacitance of a charged
capacitor, you might damage your meter.
2. Set the rotary switch to either Lo or Hi of CAP range.
Lo: nF 2/20/200 High: µF 2/20/200
3. Insert the discharged capacitor into the CAP + and - clips connector.
Your meter displays the capacitance value.
Notes:
• For polarized capacitors, be sure to insert the negative lead in the —
(minus) clip.
• In this mode's Hi, the auto power off function does not work.
6-8. dB Measurement (M-3640D/3660D only)
WARNING: DO NOT TRY TO MEASURE A VOLTAGE GREATER
THAN 20V AC. YOU MIGHT DAMAGE YOUR METER AND
EXPOSE YOUR SELF TO A SEVERE SHOCK HAZARD.
Follow these steps to measure the dB (decibels)
1. Set the rotary switch to the desired position with 2 steps input
voltages: 200mV & 20 V AC range.
2. Connect the meter in parallel with the load or circuit.
