Operation

7-1.AC Current Measurements
Open the flexible coil clamp meter power and will be single phase is in flexible coil, and a locking knob, so that the measured single phase in the flexible coil of central, in order to obtain the best measurement results. The results of the measurements will be displayed on the LCD screen.

7-2.Power button
Short press the power button to boot, and long press the power button to shut down.
7-3.MAX/MIN Button

Press the MAX/MIN button to activate the MAX/MIN mode. The “MAX” indicator will appear on the LCD display along with the highest reading. The display will update every time a higher “MAX” occurs.
Momentarily press the MAX/MIN button again to view the lowest reading. The “MIN” indicator will appear on the LCD display along with the lowest reading. The display will update every time a lower reading occurs.
Press and hold the MAX/MIN button to end MAX/MIN and return to normal operation.

7-4.Data Hold/Backlight Button
Short press this button, the measured AC current value is displayed on the LCD screen, and then the short press is canceled. Long press this button to turn on the backlight, press the button again to turn off the backlight.

7-5.Automatic Power OFF
In order to save power, the instrument without any key operation, automatic shutdown after about 15 minutes. After the shutdown press, the power button once again opens the instrument.
