10.2.4. DS Set Display Step Size [ Index 0x2216 ]
This command allows the output to step up or down by a unit other than 1.
Permitted values are 1, 2, 5, 10, 20, 50, 100, 200 and 500.
Master (PC / SPS) sends Slave (DAD 141.1) responds Meaning
DS S+00002 Request: Step size 2
CE E+00017 (example) Request: TAC counter CE17
CE 17 OK Calibration sequence active
DS 50 OK Setup: Step size 50
Legal for trade applications allow for up to 10000 intervals. The allowed step size has to be considered.
Factory default: DS = 00001
10.2.5. DP Set Decimal Point Position [ Index 0x2214 ]
This command allows the decimal point to be positioned anywhere between leftmost and rightmost digits of the
5-digit output result. Permitted values are 0, 1, 2, 3, 4, 5. Position 0 means no decimal point.
Factory default: DP = 00000
Master (PC / SPS) sends Slave (DAD 141.1) responds Meaning
DP P+00003 Request: Position of decimal point 3
CE E+00017 (example) Request: TAC counter CE17
CE 17 OK Calibration sequence active
DP 0 OK Setup: no decimal point
10.2.6. CZ Set Calibration Zero Point [ Index 0x2212 ]
This is the reference point for all weight calculations, and is subject to TAC control.
Factory default: approx. 0 mV/V input signal
Master (PC / SPS) sends Slave (DAD 141.1) responds Meaning
CE E+00017 (example) Request: TAC counter CE17
CE 17 OK Calibration sequence active
CZ 0 OK Zero point saved
10.2.7. CG Set Calibration Gain (Span) [ Index 0x2206 ]
This is the reference point for calibration with load, and is subject to TAC control.
Permitted values are from 1 to 999 999.
Master (PC / SPS) sends Slave (DAD 141.1) responds Meaning
CG G+010000 Request: Calibration weight = 10000 d
CE E+00017 (example) Request: TAC counter CE17
CE 17 OK Calibration sequence active
CG 15000 OK Setup: Calibration weight = 15000 d
For calibrating an input signal near the display maximum (CM) will give the best system performance. The
minimum calibration load of at least 20% is recommended. Is the calibration weight smaller than 1% of display
maximum (CM), the DAD 141.1
will respond with an error message (“ERR”).
Factory default: 10000 = 2.000 mV/V input signal
