Inrush current measurement of True RMS Clamp multimeter GD169A
1) Turn the knob to 
，and select Proper range(60/600A or 1000A), Press FUNC key until the "inrush" character is displayed
2) Then press the trigger to open the clamp, clamp the conductor to be tested, and then slowly release the trigger until the clamp are completely closed, and determine whether the conductor to be tested is clamped in the center of the pliers, if the conductor is not in the center of the pliers, additional errors will occur.
3) Turn on the equipment to be tested (such as motor) and then trigger the meter by inrush current
4) Read the measurement results on the display
