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 = 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
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.
