stabilize.
The instrument
displays lower
values than the
actual voltage.
52
What to check
Is the measurement
target's frequency
50 Hz or 60 Hz? The
instrument does not
support the frequency
of 400 Hz.
Have the voltage
sensors been properly
attached to the
measurement targets
(wires)?
Have multiple
voltage sensors been
attached to the same
measurement target
(wire)?
Does the insulated
wire of the
measurement target
have any dirt or
moisture on it?
Solution
The instrument
is designed
exclusively for use
with 50 Hz and
60 Hz circuits.
(The accuracy
guarantee only
applies to the
frequency range
of 45 Hz to 66 Hz.)
The instrument
cannot be used to
measure 400 Hz
circuits accurately.
Check how the
voltage sensors
have been
attached to the
wires.
Attach each
voltage sensor to
only one wire.
Wipe it clean with
a dry cloth before
measurement.
