Trouble-Shooting - Ahlborn ALMEMO 1036-2 Operating Instructions Manual

18. TROUBLE-SHOOTING

This measuring instrument can be configured and programmed in many differ-
ent ways. It is suitable for connecting a wide variety of different sensors and
peripheral equipment. Given these numerous possibilities the device may in
certain circumstances not always behave quite as expected. The cause of
such unexpected behavior is only very rarely a device defect; usually the
cause is incorrect operation by the user, an invalid setting, or unsuitable ca-
bling. In such event try to pinpoint and clear the problem with the aid of the fol-
lowing tests.
Error No display, display malfunction, keys do not react.
Remedy Check the power supply; replace the batteries; switch off and then on
again; if necessary re-initialize. (see 7.4)
Error Measured values are incorrect.
Remedy Check the status of the measuring channel, in particular the
offset. (REL)
Error Measured values fluctuate unexpectedly or the system hangs in mid-
operation.
Remedy Check the cabling for any inadmissible electrical connections; unplug
all sensors and replace with hand-held sensors in air or phantoms
(for Pt100 sensors, 100 ohms) and test again; then reconnect the
sensors one after the other and test again. If a fault persists for any
one connection, check all wiring; if necessary, insulate the sensor
and eliminate interference by using shielded or twisted wiring.
Error Data transmission via the interface does not function.
Remedy Check the interface module, connections, and settings. Ensure that
both devices are set to the same baud rate and transmission mode.
(see 16.4) Test data transmission by means of a terminal.
If the computer is in XOFF status. enter <ctrl Q> for XON.
Check the programming by means of ´P15´. (see Manual, 6.2.3)
Test the transmit line by entering a smoothing factor using command
´f1 z10´ and check in ´Sensor programming´. Test the receive line
by a memory output in the ´Functions´ menu by pressing
<PRINT>
and
If, after performing the above-listed checks and remedial steps, a device still
fails to behave as described in the operating instructions, it must be returned to
our factory in Holzkirchen, accompanied by a brief explanatory note, error de-
scription, and if available test printouts. With the AMR-Control software you
can print out screenshots showing the relevant programming details and save
and / or print out a comprehensive ´Function test´ in the device list or terminal
mode.
and check the display.
