Correct measurement of resistance, conduction and frequency with clamp ammeter
Method of measuring resistance
First, set the function switch to the position.
Second, insert the red test line into the V/Ω port and the black test line into the COM port.
Third, make the contact of the test line short-circuit, and press the zero adjustment switch to eliminate the resistance of the test line.
Fourth, connect the test line to the test loop. Humidity sensor probe, stainless steel electric heating tube PT100 sensor, cast aluminum heater, heating ring fluid solenoid valve.
It should be noted here that do not measure in the electrified circuit to avoid possible electric shock accidents and damage to the instrument or circuit. Remove all test wires on 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
First, set the function switch to the position.
Then, insert the red test line into the V/Ω port and the black test line into the COM port.
Then, make the contact of the test line short-circuit, and press the zero adjustment switch to eliminate the resistance of the test line.
Next, press the mode selection switch to switch the normal mode to the conduction detection mode and display the ""sign.
Finally, connect the test wire to the test loop. If the test resistance is lower than 20.0Ω, the buzzer will buzz.
Measurement method of frequency
First, set the function switch to the A or V position.
Then, press the mode selection switch for 3 times to switch the normal mode to the frequency measurement mode and display the "Hz" sign.
Finally, according to ACA or ACV measurement process.
