Measuring Voltage in LoZ Mode
To use dB or dBm function, turn the rotary switch to ACV or
ACmV position. Then move the blink cursor of menu to
dB or dBm position, and press the ENTER button to enter
function.
Press the CANCEL button to exit function.
Caution
• Do not use the LoZ mode to measure voltages in circuits
that could be damaged by this mode’s low impedance.
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.
Measuring AC and DC Current
• Always use proper terminals, switch position, and range for
measurements.
• To avoid possible electric shock or personal injury, never
attempt an in-circuit current measurement where the open
circuit potential to earth is greater than 1000V.
• Only replace the blown fuse with the proper rating as
specified in this manual.
