C.4.3 Calibration Commands – CE, CI, CM, DS, DP, CZ, CG, AZ, AG, ZT, FD, CS
Note:
TAC represents Traceable Access Code (calibration counter).
CE
TAC counter reading
With this command you get the TAC counter reading or you can enable a calibration sequence.

(example)
Request: TAC-counter CE17
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.
CI
Set minimum output value
This command is used for setup minimum allowable output value. Permitted values are 0 ... -99 999

(example)
Request: TAC-counter CE17
CE_17
¿
OK
Calibration sequence active
CI_-10000
¿
OK
Setting: CI = -10 000
This value will determine the point at which the output will change to “uuuuuu”, signifying under-range.
Factory default setting: -9 000.
CM
Set maximum output value
This command is used for setup the maximum output value. Permitted values are between 1 … 99 999.

M+30000
Request: CM = 30 000
CE

E+00017
(example)
Request: TAC-counter CE17
CE_17
¿
OK
Calibration sequence active
CM_50000
¿
OK
Setting: CM = 50 000
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 = 99 999.
