Measuring Voltage in LoZ Mode
• Do not use the LoZ mode to measure voltages in
circuits that could be damaged by this mode’s low
impedance.
CAUTION
!
To eliminate ghost voltages, the meter’s LoZ mode
presents a low impedance across the leads to obtain a
more accurate measurement. The ranges of measuring
LoZ voltage are 400V and 1000V. In this mode, meter
will automatic measure input signal which is AC or DC
and determine range.
To use the LoZ mode, turn the rotary switch to LoZ
position.
