c. Read the measured value from the LCD display. The actually measured frequency will be displayed in the upper

LCD.

NOTE: If the true RMS value is less than 3A, the frequency of the signal will be displayed as 0 (Please refer to the

following figure.

III.1.2. HOLD, MAX, MIN and PEAK of AC Current.

a. Set the sliding switch at A.

b. Connect the flexible probe around the conductor. Keep the probe coupling more than 25mm away from the

conductor.

c. The measured value from the LCD display. If the HOLD button is pressed, the symbol of "HOLD", "MAX", "MIN"

or "PEAK" will be shown in LCD alternatively. And the value of the HOLD, MAX, MIN or PEAK function will be

displayed in LCD alternatively.

d. To return to the display of current measurement, hold the HOLD button for more than 2 seconds.

NOTE: The PEAK function displays the maximum value of the input waveform. The sampling time for the PEAK

function is 39 μs (50Hz) or 33μs (60Hz). The HOLD, MAX, or MIN function displays the true RMS value.

NOTE: If the peak value of the input AC voltage is greater than the maximum value of the range, then symbol of OL

will be displayed.

WARNING: Maximum input for ACV is 600. Do not attempt to take any voltage measurement that exceeds the

limits. Exceeding the limits could cause electrical shock and damage to the clamp meter.
