Parameters
Parameter Name Parameter Type Range of Values Default Units
<mode>
boolean OFF | 0 | ON | 1 | ONCE none
Comments • You can substitute decimal values for the OFF ("0") and ON ("1") parameters.
• When autozero is ON, the multimeter makes a zero measurement (measurement
with input disabled) following every measured reading and subtracts the zero
measurement from the reading. This doubles the time required per reading.
• When autozero is OFF, the multimeter makes one zero measurement and subtracts
this from all subsequent measurements. A new zero measurement is made
whenever the function is changed. Notice that the mode parameters
OFF and
ONCE have the same effect.
• An autozero measurement is not made following a range change whether autozero
is
ON or OFF.
• Autozero cannot be used when a 10 µs aperture time is specified.
• The CONFigure and MEASure commands turn autozero ON.
• *RST Condition: CAL:ZERO:AUTO ON
Example Turning Autozero OFF
CAL:ZERO:AUTO OFF !Disable autozero.
:ZERO:AUTO?
CALibration:ZERO:AUTO? returns a number to show whether the autozero mode
is enabled or disabled: "
1" = ON, "0" = OFF or ONCE.
The number is sent to the output buffer.
