2-5 It is impossible to
perform zero-
adjustment.
Measured values before zero-adjust-
ment exceed -3% to 50% of each range
full-scale, or a measurement fault has
occurred.
There is a problem with the wiring.
Repeat zero-adjustment with
the correct wiring. Since zero-
adjustment cannot be per-
formed if the resistance value is
too high, for example with a
user-made cable, work to mini-
mize the wiring resistance.
