ERROR _ PORT?
Returns the current pressure port for percent error mode.
For example:
If you send ERROR _PORT?, it will return P1 if the pressure
port in percent error is [P1].
FUNC
Sets the display indicated in argument one to the function
indicated in argument 2.
For example:
To set the lower display to pressure mode send FUNC
LOWER,[P1].
FUNC?
Returns the current mode of all displays. For example if the
calibrator is set to [P2] ST on the upper display, [P1] on the
middle, and [P1] on the lower, FUNC? Would return:
ST_P2,P1,[P1]
HART_ON
Turns the Hart resistor on.
HART_OFF
Turns the Hart resistor off.
HART?
Returns the state of the Hart resistor.
For example:
If the Hart resistor was on HART? Would return ON.
HI_ERR
Sets the 100% point for the percent error mode calculation in the
current engineering units.
For example:
To set the 100% point to 100 psi send HI_ERR 100.
