6.3.10 (AL.) Alarm
There are three possible settings: Alarm off (AL.oFF), on (AL.on), on (AL.no.So).
The following conditions will prompt an alarm to be displayed, if the alarm function is
activated (on or no.So):
■
Value is below lower alarm limit (AL.Lo) or above upper alarm limit (AL.Hi).
■
Sensor error (Sens-Erro)
■
Low battery (bAt)
■
Fe 7: System error
When an alarm occurs, the alarm arrow flashes, and, during serial communication, the
‘PRIO’-flag is set within the transmitted message.
6.3.11 (CLOC) Real time clock
The real time clock is needed for time-stamping each data point recorded within the
logger function. As a result, the clock settings should be checked regularly. If the battery
has been replaced the appropriate menu ‘CLOC’ will be accessed automatically.
6.4 Operation of logger
The device supports two different logger functions:
" Func-STOR " : Each time the ´STORE/QUIT´ key is pressed a data point will be recorded.
" Func-CYCL " : Measurements will automatically be recorded at a defined interval, set
within the logger menu ‘CYCL‘ until the logger is stopped or the logger
memory becomes full. Logging is started by pressing the ´STORE/
QUIT´ key for 2 seconds.
The logger records up to 3 measurement values for each interval:
■
Current or mean value (depending on logger setting, see below), Min-Peak and
Max-Peak. (Sensor 1, Sensor 2, difference)
To evaluate the data, WIKA’s Data logger evaluation software GSoft (V 2.3 or higher)
must be used. The software also allows easy configuration and operation of the logger.
If the logger is selected (Func-STOR or Func-CYCL) the hold function is deactivated; the
´STORE/QUIT´ key is then used solely for the operation of the logger functions.
Min- and Max-Peak are, respectively, the minimum and the maximum measured values
during the last measurement interval. Therefore both the instantaneous pressure values
and the measured fluctuations can be better analysed.
