ENGLISH
– Use the LPF function to improve measurement
on composite sine waves that are typically
generated by inverters and variable frequency
motor drives.
Z
LOW
measurements (U1272A only):
–Use the Z
LOW
(low input impedance) function
to detect ghost or induced voltages.
– Ghost voltages can be caused by capacitive
coupling between energized wiring and
adjacent unused wiring.
Qik-V test (U1271A only):
– Use the Qik-V function to quickly identify the
measured signal type.
– Use this function as a reference to determine
if the measured signal is an AC or DC signal,
then select the appropriate voltage
measurement function by turning the rotary
switch to an appropriate position (AC or DC).
Rotate the rotary switch’s position to
to enable low impedance
measurements.
Rotate the rotary switch’s
position to to enable the
Qik-V function.
