CALRSTZ Reset Zero Offset Calibration Constant Command
Input: CALRSTZ <input>, <type>[term]
Format: a,nn
<input> Specifies which input for which to reset the zero offset calibration constant to the
default value. Valid entries are A or B for inputs and V for the analog output.
<type> Specifies the input sensor type. Valid entries are:
0 = Silicon Diode 6 = Thermo/25mV
1 = GaAlAs Diode or
Analog Output 7 = Thermo/50mV
2 = 100
Ω Plat/250 – Reversal Off 10 = 100Ω Plat/250 – Reversal On
3 = 100
Ω Plat/500 – Reversal Off 11 = 100Ω Plat/500 – Reversal On
4 = 1000
Ω Plat – Reversal Off 12 = 1000Ω Plat – Reversal On
5 = NTC RTD – Reversal Off 13 = NTC RTD – Reversal On
Remarks: Resets the zero offset calibration constant for a specific input and type to its default value.
CALSAVE Calibration Save Command
Input: CALSAVE [term]
Remarks: Saves all CALZ and CALG calibration constants to the E
2
prom.
CALZ Zero Offset Calibration Constant Command
Input: CALZ <input>, <type>, <value>[term]
Format: a,nn,±nnnnnnn
<input> Specifies which input or analog output the zero offset calibration constant will be
provided to. Valid entries are A or B for inputs and V for the analog output.
<type> Specifies the input sensor type. Valid entries are:
0 = Silicon Diode 6 = Thermo/25mV
1 = GaAlAs Diode or
Analog Output 7 = Thermo/50mV
2 = 100
Ω Plat/250 – Reversal Off 10 = 100Ω Plat/250 – Reversal On
3 = 100
Ω Plat/500 – Reversal Off 11 = 100Ω Plat/500 – Reversal On
4 = 1000
Ω Plat – Reversal Off 12 = 1000Ω Plat – Reversal On
5 = NTC RTD – Reversal Off 13 = NTC RTD – Reversal On
<value> Zero offset calibration constant value.
Remarks: Provides the zero offset calibration constant for the selected input or analog output.

Format: a,nn
<input> A, B, or V
<type> 0 – 7 or 10 – 13
Returned: <value>[term]
Format: ±nnnnnnn (Refer to command for description)
