4. Communications issues
The communications monitor (p.131) function can be used to more easily check operation.
3-5 EOM is not being
output.
The measured value is not being
updated.
See No. 3-2 above.
p.165
EOM signal logic (The EOM signal turns ON when
measurement completes.)
−
EOM signal setting Pulse The pulse width is too narrow, and
the EOM signal is not being read
while it is on.
Increase the EOM signal’s pulse
width setting or set the EOM sig-
nal setting to “hold.”
p.114
Hold The measurement time is too
short, and the interval during which
the EOM signal is OFF cannot be
detected.
Change the EOM signal setting
to “pulse.”
p.114
3-6 The Hi, IN and Lo
signals are not
being output.
The instrument’s comparator lamp is
off.
See No. 1-3 above.
p.160
The output mode is set to BCD. Change to judgment mode (in BCD
mode, the result of a logical OR
operation applied to Hi and Lo is
output from one signal line).
p.116
3-7 The BCD signal
is not being out-
put.
The output mode is judgment mode. Change to BCD mode.
p.116
The BCD_LOW signal is not being
controlled.
Control the BCD_LOW signal (fail-
ure to do so will cause only the
upper digits to be output).
p.93
3-8 The
RANGE_OUT
signal is not
being output.
The BCD_LOW signal is not being
controlled.
Control the BCD_LOW signal (fail-
ure to do so will cause the range
signal not to be output).

No Issue Items to check Possible causesSolutions See
4-1 The instrument is
not responding at
all.
Display RMT is not
being displayed.
No connection has been established.
Check whether the connector has
been connected.
Check whether the interface settings
have been configured properly.
(USB) Install the driver on the control
device.
(RS-232C) Use a cross cable.
(USB, RS-232C) Check the COM port
number on the control device.
(RS-232C) Use the same communica-
tions speed for the instrument and the
control device.
p.123
RMT is being
displayed.
Commands are not being accepted.
Check the software delimiter.
