Automatic Use of a Motor (MOT,A) 4-11-8
As the FDI 2056 does not incorporate a motor driver, this command calls an
external library that can be tailored by the end user. Please read the section 4-3
for more details.
Assuming the user has provided the adequate software layer, the instrument will
behave as follows:
Apart from the three commands MOT,+ , MOT,- and MOT,S , which are used to
start and stop the motor, there is also the possibility of controlling the motor
automatically during a measurement cycle. Thus the motor starts when the
RUN
command is received and stops when the measurement cycle is completed.
This automated mode is entered after the reception of the MOT,A command and
exited at the reception of the MOT,S command.
Autotest (TST and AUT) 4-11-9
Each time the FDI 2056 is powered up it performs an autotest, which lasts five
seconds and performs five preset measurements and verifies the results. During
the autotest the display shows the word "Test". Once finished, if the autotest was
successful, the display will show the channel to which it is assigned and the
current value of the gain. Should the test prove incorrect, the display will show
one of the following words "!CAL"
, “!MEM”, “!INP” or “!RNG”.
Message Cause

!CAL The internal compensation file is corrupt.
You may either :
Proceed to a full compensation by sending the ADJ,2 command
which will perform the measurements needed and update the user
compensation parameters.
or
Restore the factory compensation parameters by sending the
ADJ,3 command which will proceed to the replacement of the user
compensation parameters with those generated during the
integrator channel production.
If the problem persists after one of these corrective operation
attempts, please contact us.

!MEM The internal system memory is corrupt.
This is a major issue, please contact us.
