After measuring the inductive load, the test line cannot be directly removed to avoid endangering the safety of testing personnel and equipment due to inductive discharge. The output terminal of this machine is equipped with a discharge circuit. When the output is turned off, the inductor will release energy through the instrument of Shanghai Rixing Electric Co., Ltd. The test line can only be removed after the discharge indicator is completed.

The instrument has been calibrated before leaving the factory. Please do not calibrate it yourself unless there are special circumstances. If calibration is indeed necessary, please use a standard median resistor with an accuracy of 0.01%.

During the experiment, unrelated items are not allowed to be stacked on or around the equipment panel.

Before starting up, please check the power supply voltage: AC 220V ± 10% 50Hz.

When replacing the fuse and accessories, please use the same model as this instrument.

Pay attention to moisture and oil contamination prevention for this instrument.

Please confirm that the tested equipment has been powered off and disconnected from other live devices during the experiment.

For safety reasons, please short-circuit all other open circuit winding terminals to ground before testing.
