Issue
Measured values
fail to stabilize.
What to check
Is the measurement
target's frequency
50 Hz or 60 Hz?
The instrument does
not support 400 Hz
frequency as a line
frequency.
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

circuits accurately.
