Using a clamp ammeter to correctly measure resistance, conduction, and frequency
Method of measuring resistance
Firstly, set the function switch to the position.
Secondly, insert the red test wire into the V/Ω port and the black test wire into the COM port.
Thirdly, short-circuit the test wire and press the zero adjustment switch to eliminate the resistance of the test wire.
Fourthly, connect the test line to the test circuit. Humidity sensor probe, stainless steel electric heating tube PT100 sensor, cast aluminum heater, heating coil fluid solenoid valve
It should be noted that do not measure in the energized circuit to avoid potential electric shock accidents and damage to the instrument or circuit. Remove all test wires from the instrument and open the battery cover. When measuring, please hold it behind the protective fence of the test line.
Conduction test of clamp ammeter
Firstly, set the function switch to the position.
Then, insert the red test wire into the V/Ω port and the black test wire into the COM port.
Then, short-circuit the test wire and press the zero adjustment switch to eliminate the resistance of the test wire.
Next, press the mode selection switch to switch from normal mode to conduction detection mode, and display the "" flag.
Finally, connect the test wire to the test circuit. If the test resistance is below 20.0 Ω, the buzzer will sound.
Frequency measurement method
Firstly, set the function switch to the A or V position.
Then, press the mode selection switch 3 times to switch the normal mode to frequency measurement mode and display the "Hz" symbol.
Finally, follow the ACA or ACV measurement process.
