Before testing a capacitor, make sure it is discharged. Use an approved method
for discharging the capacitor. Improperly discharging a capacitor can be danger-
ous and may cause user injury.
Referring to Figure 7, connect the test probes to the capacitor to be tested. If
appropriate, observe the proper polarity. Read the capacitance on the display.
Note:
Larger value capacitors take longer to test. A 100uF capacitor may take as long as
15 seconds to test. The Capacitance Test is Autoranging only. Manual ranges
cannot be selected.
9.7 Frequency and Duty Cycle Measurement
Frequency and Duty Cycle can be measured in the
V
or
Hz
modes.
The Frequency mode is autoranging (although the Auto annunciator does not ap-
pear). Frequency ranges cannot be manually selected.
The Duty Cycle mode is single range only.
Refer to Section 7.0, Preparation For Use, and Section 8.0, General Measurement
Procedures, before attempting any measurements.
Attach the test leads to the meter. The red lead is connected to the
V
Ω
Hz
Jack,
and the black lead is connected to the
COM
Jack. Rotate the FUNCTION switch to
the
Hz
position or the
V
position. If the
Hz
position is selected, the meter is
ready to measure Frequency immediately. If the
V
position is selected, the
Hz/DUTY
button must be pressed to put the meter into the
Hz
mode. If measure-
ment of Duty Cycle is desired, press the
Hz/DUTY
button again
(in either
the
Hz
or
V
mode). The
Hz
annunciator will change to a
%
annunciator.
Make certain that the
annunciator on the display is not visible. If it is visible,
press the D-HOLD button to turn it off.
In the Frequency mode, with the leads open, the display usually displays “0.000Hz”.
In the Duty Cycle mode, the meter usually displays “000.0%”.
Using the appropriate precautions, connect the test leads to the circuit to be mea-
sured. Read the Frequency or Duty Cycle from the display.
