B-6 Calibration Reference Models 2510 and 2510-AT
SENSe commands
:VOLTage
(:CALibration:PROTected:SENSe:VOLTage)
(:CALibration:PROTected:SENSe:VOLTage:DATA?)
Purpose
To calibrate the Peltier voltage measurement.
Format
:cal:prot:sens:volt <DMM_Reading>
Parameters
<DMM_Reading> = 3.5 to 12.5[V] = cal at + F.S.
-2.5 to 2.5[V] = zero cal
-3.5 to -12.5[V] = cal at - F.S.
Query
:cal:prot:sens:volt:data?
Description
The :CAL:PROT:SENS:VOLT command calibrates the Model 2510 Peltier
voltage measurement. During the calibration process, this command is sent
three times; once each with parameters of approxiF.S, 0, and -F.S.
The actual parameters are voltage readings taken with a precision DMM.
The :CAL:PROT:SENS:VOLT:DATA? query allows you to request the
Peltier voltage calibration parameters.
Example
:CAL:PROT:SENS:VOLT 8.51
Calibrate positive voltage.
:CURRent
(:CALibration:PROTected:SENSe:CURRent)
(:CALibration:PROTected:SENSe:CURRent:DATA?)
Purpose
To calibrate the current measurement.
Format
:cal:prot:sens:curr <Resistor_Value>
Parameters
<Resistor_Value> = 0.5 to 1.5[
Ω
]
Query
:cal:prot:sens:curr:data?
Description
The :CAL:PROT:SENS:CURR command calibrates the Model 2510 cur-
rent measurement. During the calibration process, a 1
Ω
(nominal) resistor
must be connected to the OUTPUT terminals, and the source is automati-
cally set to +4.5V, 0V, and -4.5V. The command parameter is the character-
ized value of the 1
Ω
resistor.
The :CAL:PROT:SENS:CURR:DATA? query allows you request the cur-
rent calibration parameters.
Example
:CAL:PROT:SENS:CURR 1.01
Calibrate current.
