2-5 Conditions When Output Data Become Unfixed
The operation status will be judged as a data unfixed status (i.e., there is no determined
data) immediately after settings changes are made, the system is reset, or laser stop input
is turned ON. This status is not an alarm status.
The data unfixed status starts at the time of restarting measurement after setting
refreshment or resetting until the number of data measurement times reaches an
average.
Under the data unfixed status, a digital output of -999.9999 [mm] and an analog
output of 11.000 [V] or 21.6 [mA]
*1
will be turned ON.
*1 This is the initial value. Under the data unfixed status, the analog output of the
system can be changed to a fixed value. For more information,
refer to
“3-3-7 Alarm Settings” – “Analog Output at Alarm”.
*2 Under the data unfixed status, the zero set input will be ignored.
*3 For cancelling the data unfixed status,
refer to
Chapter 5
“Troubleshooting”.
For example, the graph on the right-hand
side shows the digital display at reset input
for NORMAL measurement.
The table below shows the measurement
value display and output under the data
unfixed status or alarm status.
