3.8 CAPACITANCE MEASUREMENTS
CAUTION
1. Discharge capacitors before connecting to the meter. Capacitors shou
ld not be measured "in circuit”. Parallel
components will invalidate the measurement.
2. Verify that power is off and that any capacitors are discharged in circuit about to be tested. A capacitor can be safely
discharged by connecting a 100 k
resistor across its leads.
3. Set function selector to capacitor position.
4. Plug black test lead into COM plug. Plug red lead into Hz
F plug.
5. Touch test leads to leads of capacitor. Be sure to observe polarity when testing polarized capacitors. Read capacity in µF at
display.
6. Accuracy Note: Measurement accuracy can be improved by first selecting the ZERO feature. Next, zero the display which
automatically subtracts any residual capacitance in the meter and test leads. After zeroing, take your measurement. The
new reading will be the true capacitance, residual capacitance subtracted from total capacitance.
7. Switch meter to
OFF
to conserve power.
3.9 AUTO POWER OFF
Auto Power Off is a feature that conserves battery power when you forget to turn the power off. When the Function switch
position has not been changed for about 30 minutes, the meter automatically turns off. If you are using the meter to make
several measurements without changing the position of the Function switch, the meter may turn off. To restart, simply rotate the
Function switch at least one position.
