3.2.6 Frequency and Duty Cycle measurement
Do not measure Frequency on high voltage (>1000V) to avoid electrical shock
hazard and/or damage to the instrument.
The Meter can measure Frequency or Duty Cycle while making either an AC Voltage or AC Current
measurement.
To measure frequency or Duty Cycle:
1. With the meter in the desired function (AC Voltage or AC Current), press the Hz % key.
2. Read the frequency of the AC signal on the display.
3. To make a duty cycle measurement, press the Hz % key again.
4. Read the percent of duty cycle on the display.
5. Set the rotary switch to the Hz range.
6. Insert the black and red test leads into the COM and Hz input terminals.
7. Connect the test leads tip in parallel with the circuit to be measured. And don't touch any electrical
conductors.
8. At frequency measuring status, press Hz % one time then meter enters duty cycle measuring
status, press it again then return to frequency measuring status.
9. Read the result directly from the display.
NOTE: In noisy environment, it is preferable to use shield cable for measuring small signal

3.2.7 Temperature measurement

To avoid electrical shock and/or damage to the instrument, do not apply more
than 250Vdc or 220Vac rms between the °C terminal and the COM terminal.
To avoid electrical shock, do not use this instrument when voltages at the meas-
urement surface exceed 60v dc or 24v rms. Ac.
To avoid damage or burns. Do not make temperature measurement in microwave
ovens.
