6.3.10 (AL.) Alarm

There are three possible settings: Alarm o (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 ashes, and, during serial communication, the

‘PRIO’-ag 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 dierent 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 dened 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, dierence)

To evaluate the data, WIKA’s Data logger evaluation software GSoft (V 2.3 or higher)

must be used. The software also allows easy conguration 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 uctuations can be better analysed.
