The VT1422A has five ranges: 0.0625 V dc, 0.25 V dc, 1 V dc, 4 V dc, and 
16 V dc. To select a range, simply specify the range value (for example, 4 selects 
the 4 V dc range). If a value is specified that is larger than one of the first four 
ranges, the VT1422A selects the next higher range (for example, 4.1 selects the 
16 V dc range). Specifying a value larger than 16 causes an error. Specifying 0 
selects the lowest range (0.0625 V dc). Specifying AUTO selects auto range. 
The default range (no range parameter specified) is auto range.
If using amplifier SCPs or RSCs, set them first and keep their settings in mind 
when specifying a range setting. For instance, if the expected signal voltage is 
to be approximately 0.1 V dc and the amplifier SCP for that channel has a gain 
of 8, <range> must be set no lower than 1 V dc or an input out-of-range condition 
will exist.
The <type> parameter specifies the sensor type that will be used to determine 
the temperature of the isothermal reference panel. <type> CUSTom is 
pre-defined as Type E with 0
°C reference junction temp and cannot be redefined. 
 For <type> THERmistor, the <sub_type> parameter may be specified in ohms 
or kilohms.
The *CAL? command calibrates resistance channels based on Current Source 
SCP and Sense Amplifier SCP setup at the time of execution. If SCP settings 
are changed, those channels are no longer calibrated. *CAL? must be executed 
again.

*RST Condition: Reference temperature is 0
°C.
