Voltage and Temperature Measurements 2-21

Programming Example - measure voltage and temperature

The following program fragments will measure voltage on Channel 1 and temperature on

Channel 2. Temperature is conﬁgured using a simulated reference junction (i.e., ice bath) and a

type K thermocouple.

‘ Configure Temperature:

CALL SEND(7,“:sens:temp:trans tc”,status%) ‘Select thermocouple

‘sensor.

CALL SEND(7,“:sens:temp:rjun:rsel sim”,status%) ‘Select simulated

‘reference.

CALL SEND(7,“:sens:temp:rjun:rsel:sim 0”,status%) ‘Set reference to

‘0˚C.

CALL SEND(7,“:sens:temp:TC K”,status%) ‘Set for type K

thermocouple.

CALL SEND(7,“:unit:temp F”,status%) ‘Read in ˚F.

‘ Measure voltage on Channel 1:

CALL SEND(7,“:sens:chan 1”,status%) ‘Select Channel 1.

CALL SEND(7,“:sens:func ‘volt’”,status%) ‘Select DCV1.

CALL SEND(7,“:sens:data:fres?”,status%) ‘Request a fresh

‘reading.

reading$ = SPACE$(80)

CALL ENTER(reading$, length%, 7, status%) ‘Address 2182 to talk.

PRINT reading$ ‘Display reading on CRT.

‘ Measure temperature on Channel 2:

CALL SEND(7,“:sens:chan 2”,status%) ‘Select Channel 2.

CALL SEND(7,“:sens:func ‘temp’”,status%) ‘Select TEMP2.

CALL SEND(7,“:sens:data:fres?”,status%) ‘Request a fresh

‘reading.

reading$ = SPACE$(80)

CALL ENTER(reading$, length%, 7,status%) ‘Address 2182 to talk.

PRINT reading$ ‘Display reading on CRT.
