Note
●When measuring large capacitances, it will take some time for the reading
to stabilize.
●When measuring polarized capacitors, pay attention to the correspond-
ing polarity to avoid damage to the meter.
Frequency measurement
1. After power on, it will automatically switch to the "AUTO" automatic measure-
ment mode, and then press the SEL key to switch to the frequency Hz measure-
ment mode.
2.Connect the black test lead and the red test lead to the COM input jack and the
INPUT input jack respectively.
3. Use both ends of the test pen to read the measured value from the LCD
display.
Temperature measurement
1. After power on, it will automatically switch to the "AUTO" automatic measure-
ment mode, and then press the SEL key to switch the measurement mode.
2. Connect the black input terminal of the thermocouple and the red test lead to
the COM input jack and the INPUT input jack respectively. Fahrenheit is
displayed along with the temperature value.
3. The LCD display reads the measured value.
If there is inductive impedance in the line, there will be flutuations
affecting the results read and the data maybe inaccurate.
It is necessary to disconnect the test, and the correct test data
will be obtained.
