5. OPERATION, MAINTENANCE AND CALIBRATION
5.1 Operating modes
After having set all necessary instrument parameters as described in chapter 4, the
instrument is ready for operation. During continuous operation, the SERVOTOUGH
LaserExact Monitor may be in any of these three modes:
1. Start-up mode
2. Measuring mode (or normal mode)
3. Fault mode (or Error mode / Sleep mode)
1. Start-up mode: After turning on the power the instrument runs through initialising,
self-test and start-up before starting measurements. This is indicated by appropriate
texts in the instrument display (LCD). The instrument stays in start-up mode until the
laser temperature stabilises within acceptable limits. The LCD typically shows the
following:
- power -
MONITOR 6.1a1
Self-test OK
Start-up 0.356
In the upper right corner of the LCD the software version used by the instrument is
printed. In this case the version is 6.1a1.
The next row shows the cause for the instrument being in start-up mode. Normally it
will show -
power- indicating that the power has recently has been switched on. In
case of a restart due to unexpected software or hardware conditions the word -
watchdog- would be printed instead.
If the self-test has passed successfully, a number appears in the lower right corner of
the LCD. This number decreases as the laser temperature stabilises. When the
number is below 0.3, the instrument slowly powers up the laser. The start-up mode
normally lasts less than 3 minutes.
2.
While the operating mode is «measuring» , the instrument can be in 4 measuring
modes:
a) «Normal»: Normal measurement,
b) «Zero»: Not applicable for LaserExact analyser
c) «Span»: Not applicable for LaserExact analyser
d) «Maintenance»: Measurements as normal but with relay 3 indicating
maintenance (if configured for maintenance, see Section 6.9).
