Calibration commands :
It is possible to start a calibration function from the remote. At the end of the
calibration (calibration flag in status registers should be tested to determine when cal
functions end), it is possible to verify the calibration error (cal error register) and
eventually accept the new zero or span.
Bit Description Action
08 Autospan RCAL Start the autospan function with RCAL
method. The Rcal is automatically
connected by instrument at the beginning of
the function and disconnected at its end.
This operation needs a delay of 0.5
seconds. In case a RCAL remote
calibration is aborted, the calibration flags
will turn off after this delay.
07 Autospan CHAIN Start the autospan function with CHAINS
method.
06 Autospan WTS Start the autospan function with WTS
method. An output of the Microtech can be
programmed to automatically load the test
weights, this adds a 10 second delay at the
beginning and at the end of the calibration
function. In case a WTS remote calibration
is aborted, the calibration flags will turn off
after this time.
05 Autozero Start the autozero function.
04 Confirm zero/span At the end of the calibration function, this
command tells the instrument to save the
new zero or span. If this command is sent
during a remote calibration, it aborts the
running function.
