Data Logging
Log On Demand
The softkey enables the user to log a single snapshot of the current
results at the instant the key is pressed, irrespective of whether the system is gating or not,
and whether logging is enabled or disabled. The output logged is dependent on the current
state of the instrument, and is defined as follows:
• , …results only logged
• , …header and results logged
• or , …header and results logged
Logging Alarms
When an alarm occurs and if the user has selected to have alarms printed, its cause (clock
loss, data loss, sync loss), occurrence time and recovery time are printed. Power fail and
recovery will always be printed regardless of whether alarms have been enabled or not. An
example of Alarms logging is given below.
1993-04-23 23:10:04 ALARM: Power Failed
1993-04-23 23:10:14 Power Restored
1993-04-23 23:10:19 Gating Resumed
To Log Alarms
Select then the softkey. The softkey is ON
when it is underlined.
NOTE In the event of a power failure, any results which were stored prior to
being sent to the printer will be lost.
Logging Squelch
The Squelch feature is intended to save paper in situations where logging is being
triggered over a long period of time. When Squelch is enabled logging is inhibited if
triggered for ten consecutive seconds. When Squelch is active a message similar to the
following is logged:
1993-04-23 23:10:03 Squelching Printing
To Squelch or not to Squelch
Only during gating triggers contribute to the decision on whether or not to squelch. Thus,
theoccurrenceofend of measurement periods do not contribute, and are logged, if the
user has indicated that they should, even when actively squelching.
