4.7Low resistance measurement
Turn the selector switch to LowZ position and connect the pen-shaped meter to the signal to be
measured. The primary display panel shows the measured voltage value. The instrument will
automatically recognize whether the measured signal is DC voltage or AC voltage.
Note: In the low resistance measurement mode, the longest duration for measurement shall not
exceed 1 minute.
4.8 Electric resistance/buzzer measurement
Connect the pen-shaped meter to the grounding resistance to be measured. The instrument will
display the measured resistance value. When the measured resistance is less than
50Ω
and the
rotary switch is switched to buzzer position, the instrument's buzzer will sound alarms.
