Crest Factor
The CF (crest factor) indicates the peak value of a signal by dividing it by its
root-mean-square value. With most common waveforms such as sinusoidal
wave and chopping wave, the crest factor is low. With low duty cycle pulse
waveforms, the crest factor is high. For the voltages and crest factors fortypical waveforms, see the table below.

Measurement Categories (Overvoltage Categories)
This instrument is a true rms AC clamp meter designed in compliance with
IEC61010-1 CAT.III 300 V/CAT.II 600 V. It is suitable for measuring thecurrent of electrical lines, appliances and power supply facilities operating on
low voltages of no more than 600 V.
CAT.II : Primary cable runs of power-consuming equipment from a wall socket
CAT.III: Primary cable runs of equipment directly connected to a distribution
board and cable runs from a distribution board to wall sockets.

ACV Measurement

Resistance Measurement

Continuity Test

Maximum Input Voltage is 600 VAC. Do not attempt to take any voltage
measurement that may exceed to avoid Electrical shock hazard and/or
damage to this instrument.

Switch the function torange.
Connect red test lead to “+” terminal and black one to the “ COM ” terminal.
Connect tip of the test leads to the points where the value of the resistance isneeded.
Read the result from the LCD display.

Switch the function torange.
Connect red test lead to “+” terminal and black one to the “ COM ” terminal.
Connect tip of the test leads to the points where the conduction condition
needed.
If the resistance is under 100 Ω, the beeper will sound continuously.

Switch the function selector to range.
Connect red test lead to “+” terminal and black one to the “ COM ” terminal.
Measure the voltage by touch the test lead tips to the test circuit where thevalue of voltage is needed.
Read the result from the LCD display.

Note:
When take resistance value from a circuit system, make sure the power is cut
off and all capacitors need to be discharged.
