Usage
[:SENSe[1]]:<function>:RELative:STATe <state>
[:SENSe[1]]:<function>:RELative:STATe?
<function>
The measure function:
• Current: CURRent[:DC]
• Resistance: RESistance
• Voltage: VOLTage[:DC]
The digitize function:
• Digitize current: DIGitize:CURRent
•
Digitize voltage: DIGitize:VOLTage
<state>
Disable the relative offset: OFF or 0
Enable the relative offset: ON or 1
Details
When relative measurements are enabled, all subsequent measured readings are offset by the
relative offset value. You can enter a relative offset value or have the instrument acquire a relative
offset value.
Each returned measured relative reading is the result of the following calculation:
Displayed reading = Actual measured reading - Relative offset value
Example
:SENS:FUNC "VOLT"
:SENS:VOLT:REL 5
:SENSe:VOLT:REL:STATe ON
Set the measurement function to volts with a
relative offset of 5 V and enable the relative
offset function.
