Display Error Cause
max Positive excess of the measuring range The measured value exceeds the max. of the range
min Negative excess of the measuring range The measured value is lower than the min. of the range
anao Failure of the analog output Output loop is not closed or short circuited
sens Sensor failure (internal) Sensor bridge not in balance, might be been overloade
data Stored data failure (EEProm) (internal) Memory failure
prog Processor failure (internal) Microcontroller failure
cal Calibration failure (internal) Calibration values are wrong
4. Operation
After the unit is switched on, the unit starts an automatic self-test.
The device is menu operated and configured by the three keys on the front.
With the „M“ key (= mode) you change between the operation / indicating level to the dialog values and the
adjusted / actual values. With the keys („
⇑“ = up) and („⇓“= down) you change between the dialog values
in the menu or change the values / functions in the menus.
A change of any configuration starts always with the M-Mode and indicated by the flashing cursor. After a
change has been made the M-mode key must be pressed to confirm each configuration; to set numbers,
each digit has to be confirmed with the M-Mode before adjusting the next one. By confirming the last digit
the new configuration will be stored in the memory.
Pushing the down key at the end of the sub-menu the software will switch automatically to the main-menu.
For a quick termination of programming you can change into the measuring mode from any level in the
menu by pressing the M-key for 5 seconds.
If the dialog is not continued within two minutes the device automatically returns to the measuring mode
without accepting the new values (see also: „List of functions“).
5. Key lock
Activating the („ ⇑“ = up) and („⇓“ = down) keys together for more than 5 seconds will block any changings
in all menues; shown by „LOCK“ in the display.
In this mode, all configuration values can be checked only, but not changed.
Repeating this action will unlock the configuration menu and shown by „UNLK“ in the display.
6. Error handling
The internal self-check software will monitor the proper functioning of the unit. When any of the following
failures will occur, the flashing display will indicate the following text:
