MODE(=)
Purpose: Read or set the control mode.
Syntax: “MODE”
“MODE=n”
Arguments:
n: ’0’ for static pressure control.
’1’ for dynamic pressure control.
Remarks: The control mode & control mode settings are selected with the MODE command. When the
control mode is set, control parameters go to default parameters for that range. The mode
setting is range specific.
Example: Command: “MODE=1”
Reply: “MODE=1”
Errors: ERR# 6 The argument is invalid.

PCALd,r(=)
Purpose: Read or set the user reference pressure transducer calibration information.
Syntax:
“PCALn,xx = adder, mult, Tare, CalDate”
“PCALn,xx”
“PCALn,xx = 0.0, 1.0, 0.0, 800101”
Arguments:
n: The transducer range. ‘1’ for the low, ‘2’ for the medium ‘3’ for the high range
of the selected transducer.
xx: The transducer. ‘Hi’ for the high pressure, ‘Lo’ for the low pressure.
adder: The transducer calibration adder from -10 000 to 10 000 Pa.
mult: The transducer calibration multiplier from 0.9 to 1.1.
Tare: The transducer PA(z)tare (Pa).
CalDate: The date of the last calibration in the format “YYMMDD”.
Remarks: The user defined pressure calibration information for the specified transducer (Hi or Lo pressure)
and transducer range (low, medium, or high) can be access with this command Using this
command will overwrite the current calibration, so caution must be used. Changes made using
this command will take affect immediately, but must be made permanent by executing the
“SAVECAL” command before the unit is powered down. If this is not done, the changes will be
lost if the unit is powered down.
Example: Command: “PCALo,2=.3, 1.000021, 1.4,960101”
Reply: “0.30 Pa, 1.000021, 1.40 Pa, 960101”
Errors: ERR# 6: One of the arguments is out of range.
