correct and match
the signal range field?
Replace the correct match signal meter, or by mail to the company to
modify the specifications
3. Input signal exceeds the
range (upper
limit of +110%
input specifications?
A. Make sure the correct input signal
B. Replace the correct match signal meter, or by mail to the
company to modify the specifications
4. Shows the corresponding
input signal value is Less
than lOsc?
If the input signal Less than the corresponding display low(lOsc set
value), the display will appear-ovfl
A. Replace the correct match signal meter, or by mail to the
company to modify the specifications
4.Wiring access terminal and
accessthe right solid?
A. Please confirm the wiring diagram on the
instrumentwiring correct? And confirm whether a signal line (two
lines) is not connected to the terminals 。
B. Choose the appropriate crimp terminals to reduce thebad or the
wiring is not strong。

B. For the moment the beat from time to time (the
loadmovement caused by the coil), try setting
a larger [Dfilt](A-07)。
C. Connect signal wires should be away from the
powerload, and use shielded twisted pair of
