(4) Read the measured frequency on the primary
readout and the duty cycle (as a percentage) on
the secondary readout in the upper right corner of
the LCD.
With the rotary function switch in the Hz position, the
meter can measure frequencies from 10Hz to 60MHz
with an accuracy of ±(0.5% of the r 3 digits).
For inputs at frequencies below 10Hz, the primary
readout will show
00.00 Hz
. For inputs at frequencies
above 60kHz, the accuracy of duty cycle
measurements is not guaranteed.
Frequency measurements can be made with the
rotary function switch in either the
position (with
input provided by current sensed by the clamp jaw) or
the
position (with input provided by the test
leads). In both cases:
• The measured frequency is displayed on the
secondary readout in the upper right corner of the
LCD.
• Measurement accuracy is limited to ±(1.5% of the
r 3 digits).
• Measurement range is limited to 10Hz to 1kHz. With
the rotary function switch in the
position, the
meter can measure the frequency of AC currents
with amplitudes up to 1A
RMS
. With the switch in the
position, the meter can measure the frequency
of AC voltages with amplitudes up to 20mV
RMS
.
MEASURING TEMPERATURE
To measure the temperature of a solid, liquid or gas:
(1) Turn the rotary function switch to the
TEMP
position. The term
K-T
will appear above the term
OL.
on the primary readout.
(2) Plug the included “K” thermocouple adapter into
the red and black jacks at the bottom front of the
meter. Make sure to insert the + (positive) plug of
the adapter into the red jack and the
COM
plug
into the black jack.
