Warning
Risk of electric shock.
Do not measure any frequency above 250V DC or AC rms to
prevent electrical shock or damage to the meter.
1) Set the changeover switch to Hz%.
2) Connect the red and black test leads to COM and the input socket
respectively.
3) Connect the other ends of the red and black test leads to the signal source or the
load at both ends.
4) Read the measured frequency value from the LCD monitor.
5) Press "FUNC" again to enter the duty cycle measurement state.
Note
：
Frequency measurement range of 10Hz ~ 10MHz, if the measured frequency is lower than
10Hz, the LCD display "000.0"; measuring more than 10MHz frequency is possible, but does
not guarantee the measurement accuracy.
4.15 Temperature Measurement
Warning
Do not input more than 30V DC voltage in the temperature
measurement file to avoid damage or damage to the instrument
1) Rotate the changeover switch to the temperature measurement range and press (press "FUNC")
in degrees Celsius or Fahrenheit.
2) Connect the negative (black) and positive (red) of the K-type thermocouple to the COM
input and input holes, respectively.
3) Place the other end (test end) of the thermocouple on the surface of the object to be
measured.
4) to be read stable by the liquid crystal display to read the measured temperature value.
