Correct measurement method using clamp meter

Introduction to the clamp ammeter and the correct measurement method using the clamp ammeter

Introduction

GHGL-9000B high and low voltage clamp ammeter has automatic insertion and extraction function, designed and manufactured for measuring high voltage current, using the latest

High-low voltage clamp-type ammeter CT technology and mask digital integration technology, consisting of dedicated high-voltage detector, wireless receiver, high-voltage insulation rod, wireless transmission can penetrate the multi-storey building barrier or straight line within 300 meters to receive the measured data. If you do not use the insulation rod, it can also be used as a high-precision low-voltage clamp-type ammeter and leakage current meter, and can accurately measure the current or leakage current of 0.1mA to 1000A.

Correct measurement with a clamp ammeter

How to use the clamp ammeter to correctly measure resistance, conduction, frequency?

Method of folding measuring resistance

First, set the function switch to the position.

Second, plug the red test lead into the V/Ω port and the black test lead into the COM port.

Third, short the test line contact, press the zero adjustment switch to eliminate the resistance of the test line.

Fourth, connect the test leads to the test loop.

It should be noted here that do not measure in the energized circuit to avoid possible electric shock and damage to the instrument or circuit. Remove all test leads from the instrument and open the battery cover. When measuring, please hold it behind the test line protection bar.

Conduction test of folding clamp ammeter

First, set the function switch to the position.

Then, insert the red test lead into the V/Ω port and the black test lead into the COM port.

Then, short the test line contact and press the zero adjustment switch to eliminate the resistance of the test line.

Next, press the mode selector switch to switch the normal mode to the conduction detection mode and display the "" mark.

Finally, connect the test leads to the test loop and the buzzer will sound if the test resistance is below 20.0 Ω.

Folding frequency measurement method

First, set the function switch to the A or V position.

Then, press the mode selector switch 3 times to switch the normal mode to the frequency measurement mode and display the “Hz” mark.

Finally, follow the ACA or ACV measurement process.
