8.6.1 Measuring Resistance using SCPI Commands
In order to measure the resistance of a PRT, you need to:
select the measurement channel
set the milliK to measure resistance
select the measurement range
set the sense current (normal or root2 current)
select 3 or 4-wire measurement
make the measurement and collect the result
To use channel 1 to make a 4-wire resistance measurement on a 25.5
Ω
SPRT up to a
maximum resistance of 80
Ω
using the normal (1mA) sense current, send the following
command sequence:
SENS:CHAN 1
SENS:FUNC RES
SENS:WIR 4
SENS:RES:RANG 80
CURR NORM
READ?
The milliK will then report the measured resistance, for example “2.52506378E001”. Send
READ?
to make subsequent measurement using the same settings.
The following command performs the same measurement:
MEAS:RES1 80,NORM,4
8.6.2 Measuring Voltage using SCPI Commands
In order to measure the voltage from a thermocouple, you need to:
select the measurement channel
set the milliK to measure voltage
make the measurement
To measure the voltage from a thermocouple connected to channel 1, send the following
command sequence:
SENS:CHAN 1
SENS:FUNC VOLT
READ?
