4.2 Calibration Commands – CE, CM, CI, DS, DP, CZ, CG AZ, AG, ZT, FD, CS
Note:
TAC represents Traceable Access Code (calibration counter).
CE
TAC counter reading
[ 2300sub03 ]
With this command you get the TAC counter reading or you can enable a calibration
sequence.
Master (PC / PLC) sends
Device responds
Result
CE
E+00017
(example)
Request: TAC-counter CE 17
CE_17 OK
Calibration sequence active
This command must be issued PRIOR to any attempt to set the calibration parameters
CZ, CG etc. In legal for trade applications the TAC counter can be used to check if critical
parameters have been changed without re-verification. After each calibration the TAC
counter increases by 1.
CM
Set maximum output value
[ 2300sub07 ]
This command is used for setup the maximum output value. Permitted values are
between 1…99999.
Master (PC / PLC) sends
Device responds
Result
CM M+30000
Request : CM = 30000
CE
E+00017
(example)
Request: TAC-counter CE 17
CE_17 OK
Calibration sequence active
CM_50000 OK
Setting: CM = 50000
This value will determine the point at which the output will change to “oooooo”, signifying
over-range.
Note:
The range, in which a scale can be set to zero (SZ) or automatic zero tracking (ZT) is
active, is +/- 2% of CM value.
Factory default: CM = 199999.
CI
Set minimum output value
[ 2300sub08 ]
This command is used for setup minimum allowable output value. Permitted values are
between -99999 … 0.
Master (PC / PLC) sends
Device responds
Result
CI I-300
Request : CI = -300
CE
E+00017
(example)
Request: TAC-counter CE 17
CE_17 OK
Calibration sequence active
CI_-10000 OK
Setting: CI = -10000
This value will determine the point at which the output will change to “uuuuuu”, signifying
under-range.
Factory default setting: -9000.
