2-16 Measurement Concepts
B) SYSTem:ZCORrect:ACQuire
The zero correct value can only be acquired while zero check is enabled. The internal offset
will become the correction value. Zero correction can then be performed with zero check dis-
abled. This acquire method makes it convenient if you need to re-zero the selected function
often.
The following command sequence uses the acquire method to zero correct the 2V range:
SYST:ZCH ON ‘ Enable zero check.
FUNC ‘VOLT’ ‘ Select Volts function.
VOLT:RANG 2 ‘ Select 2V range.
INIT ‘ Trigger one reading.
SYST:ZCOR:ACQ ‘ Acquire zero correct value.
SYST:ZCH OFF ‘ Disable zero check.
SYST:ZCOR ON ‘ Perform zero correction.
The INITiate command in the above sequence is used to trigger a reading. This reading is the
offset that is acquired as the zero correct value. See Section 9 for more information on INITiate.
NOTE Sending the :ACQuire command while zero check is disabled will result in an error.
The command will not be executed.
