Using the Meter
Display Hold
During the measuring, press the “ B.L./HOLD ” button once to hold
the reading, press again to release hold.
Manual Measurement

When switching between positions on the rotary switct, the
default range type is Auto. Press “ RANGE ” button to enter
Manual mode. Each press increases the measuring range and will
return to minimum range after maximum has been reached.

Hold “ RANGE ” for 2 seconds to switch back to Auto mode.
Attention:
Manual Measurement Mode is disabled when performing
capacitance or frequency measurement.
Frequency and Duty Ratio

When the Meter is on AC Voltage or AC Current Mode. Press
“ Hz/% ” button once to measure the frequency of the circuit.
Press “ Hz/% ” button again to measure the duty of the circuit. If
the Meter is on HZ/DUTY mode, “ Hz/% ” button will switch
between Hz and Duty.

Press“ Hz/% ” button again to measure voltage or current
