Instruction Manual
DM08
Self-test
[off]
Example:
The default setting for the monitoring function
for the field coil current is „on“.
For changing the parameter please refer to the
description in Section "Selection window / make
a selection".
Notice
During the sampling time for the field
coil current of 0,5 seconds, the trans-
mitter is offline. The last measured value will be
shown at the signal outputs.
Self-test period (STP)*:
Using this function the time gap for the period-
ical measurement of the field coil current is
defined.
The time gaps can be set within bounds of
35
to 999 s
.
After selecting the function Self-test period
(STP) using the key
▲
or
▼
, press the ENTER
key for entering the parameter level. The cur-
rent setting for the STP will be displayed:
Self-test
STP = 040 s
Example:
For changing the parameter please refer to the
description in Section "Input window / modify a
value".
* The parameter
Self-test period (STP)
is of
relevance only, if the parameter
Self-test
is set
to „on“.
Reference calibration on / off:
The function
Reference calibration
on/off
is used to enable or disable the period-
ical recalibration of the transmitter. This function
is useful for periodical self-monitoring and for
maintaining the long-term stability of the display
electronics.
After choosing the function
Reference calib-
ration on/off
by the use of key
▲
or
▼
and
pressing Enter, the following selection field will
be displayed:
Reference calib.
[off]
Example:
For changing the parameter please refer to the
description in Section "Selection window / make
a selection".
Reference calibration period (GAP):
This function
Reference calibration
period
is used to define after how many STPs
the reference calibration will be performed.
Example:
The Self-Test period (STP) is set to 40
seconds. The reference calibration should be
performed every 6 hours. Therefore you have to
enter for the GAP:
5400
40s
3600s

press the ENTER key. The current setting for
this parameter will be displayed:
