Error messages/remedial action
Calibration status
The calibration status is OK, there are no errors present.
(Auto)calibration could not be implemented, the permissible error limit is
exceeded and the measured values are invalid.
((Auto)calibration is currently underway.
(Auto)calibration should really be implemented.
But this cannot be implemented, as the calibration or zero signal is already
in use.
This happens when when you display the internal zero signal (Zero) or
calibration signal (Cal) for a channel.
The error limit can lie outside the device tolerance.
In the DMP41 specifications, all channels can be used to measure while an
Autocal process is being run. Measurement is not interrupted or affected.
The information table shows which channel is in a calibration cycle.
The adjustment required after the warm-up phase of the DMP41 is minimal
and imperceptible.
During autocalibration (actually auto-adjustment), an internal reference
signal is cyclically switched to the amplifier and the amplifier drift
compensated in order to maintain the 5 ppm error limit. This process does
not affect measurement, the measuring process can proceed normally.
It is possible to switch the internal reference signal (Zero and Cal) to the
amplifier input as a control signal (this is only possible on one channel at a
time).
In this case, the control signal (Zero or Cal) is displayed and is no longer
the measured value of the transducer.
Autocalibration is prevented on all channels for as long as the control signal
is switched to a channel.
DMP41 calibration is implemented in the factory on a traceable BN100. No
further calibration is implemented on site, the stability is ensured by the
internal inductive reference.
