Calibration Specific Interface Commands
CALG
Gain Calibration Constant Command
Input:
CALG <input>, <type>, <value>[term]
Format:
a,nn,±nnnnnnn
<input>
Specifies which input or analog output the gain 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 = 100
Ω
Plat/250 – Reversal On
3 = 100
Ω
Plat/500 – Reversal Off
11 = 100
Ω
Plat/500 – Reversal On
4 = 1000
Ω
Plat – Reversal Off
12 = 1000
Ω
Plat – Reversal On
5 = NTC RTD – Reversal Off
13 = NTC RTD – Reversal On
<value>
Gain calibration constant value.
Remarks:
Provides the gain calibration constant for the selected input or analog output.

Remarks:
Returns 6-digit value of selected input reading. Used for CALZ and CALG functions.
CALRSTG
Reset Gain Calibration Constant Command
Input:
CALRSTG <input>, <type>[term]
Format:
a,nn
<input>
Specifies which input for which to reset the gain 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
