2) Connect the red and black test leads to the
COM
and
jack respectively.
3) Connect the other two ends of the red and black test
leads to the signal source or both ends of the load.
4) Read the measured frequency value from the LCD.
5) Press "SEL" again to enter duty cycle measurement.
Note
：
The measurement range of the frequency is 10Hz ~
10MHz. If the measured frequency is lower than 10Hz,
the LCD will display "000.0". It is possible to measure
the frequency above 10 MHz, but the measurement
accuracy is not guaranteed.
4.15 Temperature Measurement
Warning
Do not enter a temperature higher than 60V AC
voltage 30V AC voltage to avoid damage or
instrument damage
1) Turn the switch to the temperature measurement
position and select (press "SEL") Celsius or Fahrenheit as
required.
2) Connect the negative terminal (black) and the positive
terminal (red) of the K type thermocouple to the
COM
input jack and input jack separately.
3) The other end of the thermocouple (test side) close to
the surface of the measured object.
4) To be read by the liquid crystal display to read the
measured temperature value.
