923 milliK manual - issue: 1.10
Example: a milliK with a voltage gain set to 1.001234 will respond to
CAL:VOLT:GAIN?
with “1.001234”
8.6.32
Command CALibrate:CURRent:GAIN
Format: CALibrate:CURRent:GAIN
<gain>[,<standard>]
Sets the
<gain>
used for current measurements. Gains outside the range 0.98 to 1.02 are
ignored. The optional
<standard>
parameter is a string that is stored in the calibration
database file (which can be exported to a USB flash drive: see section 5.4) to provide
information about this calibration. Typically it would be used to identify the serial number of
the standard used. Example: for a milliK that has been found to require a current gain of
1.001234 by using a reference standard with serial number xyz1956, the gain can be set
using:
CAL:CURR:GAIN 1.001234,SN_xyz1956
or
CAL:VOLT:GAIN 1.001234
8.6.33
Command CALibrate:CURRent:GAIN?
Format: CALibrate:CURRent:GAIN?
Reports the current measurement gain.
Example: a milliK with a current gain set to 1.001234 will respond to
CAL:CURR:GAIN?
with “1.001234”
8.6.34
Command CALibrate:RJC:OFFSet
Format: CALibrate:RJC:OFFSet
<offset>[,<TC type>][,<serial#>][,<info>]
Sets the
<offset>
(in °C) added to measurements of thermocouple reference junction
temperatures. Offsets outside the range ±10°C are ignored. The optional parameters are
strings that are stored in the calibration database file (which can be exported to a USB flash
drive: see section 5.4) to provide information about this calibration. Typically these would be
used to store information on the thermocouple type used in the calibration, the serial number
of this thermocouple and additional information such as the serial number of the temperature
source used.
