14.1 Troubleshooting
288
2-3 No measured
value is dis-
played.
Measured values Nothing is
shown.
Auto-ranging is not selecting a range.
→
See No. 2-4 below.
p.288
No measured
value is shown,
even if the mea-
surement leads
are shorted. The fuse may have tripped.
→
Cycle the instrument's power and
perform the self-test to check
whether the fuse has tripped.
→
When using the multiplexer, if the
measured value is not displayed
after replacing the measurement
fuse, the multiplexer unit’s fuse
may have tripped. Have the Z3003
repaired.
p.44
2-4 Auto-ranging is
not selecting a
range.
(The range is not
appropriate.)
Measurement tar-
get Transformer,
motor Auto-ranging is not able to select a
range for measurement targets that
have high inductance.
→
Use a fixed range.
p.49
Noise may be affecting measure-
ment. See Appendix 7(1)(2).
p.A19
2-5 It is impossible to
perform zero-
adjustment.
Measured values before zero-
adjustment exceed -1% to 50% of
each range full-scale, or a measure-
ment fault has occurred. There is a problem with the wiring.
→
Repeat zero-adjustment with the
correct wiring. Since zero-adjust-
ment cannot be performed if the
resistance value is too high, for
example with a user-made cable,
work to minimize the wiring resis-
tance.
p.A7
2-6 The auto-hold
function is not
working (hold
operation is not
being canceled).
Measured values Are unstable. See No. 2-1 above, “Measured val-
ues are unstable.”
p.285
Do not change. An appropriate range has not been
selected.
→
Select an appropriate range or use
auto-ranging.
