10. TROUBLE - SHOOTING

ALMEMO 2390-5 measuring instruments can be configured and programmed
in many versatile ways. These measuring instruments are suitable for con-
necting a wide variety of very different sensors, additional measuring instru-
ments, alarm signaling devices, and peripheral equipment. Given these nu-
merous possibilities the devices may in certain circumstances not behave quite
as expected. The cause of such unexpected behavior is only very rarely a de-
vice defect; more usually it is incorrect operation by the user, an invalid setting,
or unsuitable cabling. In such event try to pinpoint and clear the problem with
the aid of the following tests :
Error :

Either no display or all display segments light up continuously.

Remedy : Check the power supply; charge the battery; switch off and then on

again; if necessary re-initialize (see 3.3) !

Error :

Measured values are incorrect.

Remedy : Check the channel programming very carefully (especially the base

value and zero point); check the entire programming using the AMR-
Control software or terminal and command P15 (see Manual, Secti-
on 6.2.3) and f1 P15 (see Manual, Section 6.10.1) !

Error :

Fluctuating measured values or segment test or the system hangs in
mid-operation.

Remedy : Check the cabling for any inadmissible electrical connections; dis-

connect the external power supply and the output modules; unplug
any suspicious sensors and replace with hand-held sensors in air or
phantoms (for thermocouples short-circuit A-B, for Pt100 sensors
use 100-

Ω

resistor) !

If these steps succeed in clearing the error, then check all wiring, if
necessary, insulate the sensors, use an electrically isolated power
supply, eliminate interference by using shielded or twisted wiring !

Error :

Data transmission via the interface does not function.

Remedy : Check interface module, connections, and settings :

Are both devices set to the same baud rate and transmission mode
(see Section 9.2) ?
Is the correct COM interface on the computer being addressed ?
Is the printer in the ONLINE status ?
Are the handshake lines DTR and DSR active ?

To check the data flow and the handshake lines a small interface
tester with LEDs comes in very handy; (in ready-to-operate status
the data lines TXD, RXD carry negative potential of approx. -9V
and the LEDs light up green, whereas the handshake lines DSR,
DTR, RTS, CTS carry approx. +9V positive voltage and the LEDs
light up red. For the duration of data transmission the data line
LEDs must flash red)
