12 Measurement
12.1 Explanation of the Status Line
Each character in the status line indicated the state of a physical quantity. For the physical quantities covered by
the status line and their order see Tab. 12.3.
The following characters are used in the status line: *, ?, H and L (see Tab. 12.4).
Limits have to be defined to indicate the status (see Tab. 12.5).
For an example see Tab. 12.6.
12.2 Service Mode
If key ENTER is pressed during the measurement, the service mode will be activated.
Press ENTER again to stop the service mode.
12.3 Reset of the Status Outputs
All alarms will be switched to their idle state by pressing key
three times during measurement. Alarm outputs
whose switching condition is still met will be activated again after 1 s. Use this function to reset alarm outputs of
type
HOLD
when the switching conditions is not met anymore.
By pressing BRK measurement will be stopped and the main menu is selected. All alarms outputs will be de-ener-
gized, independently of the programmed idle state. After a cold start, all alarm outputs will be re-initialized.
12.4 Protection against Interruption
The function
SET PROGRAM CODE
allows to input a program code that must be entered to interrupt a current mea-
surement.
To interrupt a current measurement, the complete program code has to be entered (=
BREAK
code). To execute a
command during measurement, it is sufficient to enter the first three digits of the program code (=
ACCESS
code).

The set measuring and display functions will be kept during service
mode (here: 60 minutes).
The last value measured before the activation will be output during
service mode.
