Reset Calibrate State
The Reset Calibrate State sets all calibration
data (i.e., sensor and temperature) to factory
values. This state purges calibration history
and should be initiated before calibrating a
new sensor.
When interrogating the calibration values
after a reset has been performed, the slope
and offset values for both the sensor and
temperature will be set to 100%/1.000 and 000
millivolts/000 C, respectively.
o
Conduct a Reset Calibration using the
following procedure.
1) Select the Reset Calibrate State of
Operation using the SELECT Key.
2) Confirm or refuse the RESET? operation
using either the YES or NO Key,
respectively.
Note: The Reset Calibration State will reset all
calibration values; therefore, the process
sensor and temperature sensor will require
calibration after performing the Reset
Calibration procedure.
Analog Output One Calibrate State
The Analog Output One Calibrate State trims
the output signal to maintain precise
transmission of the process variable to the
final monitoring system. Though the TB84PH
Advantage Series analyzer output current is
factory calibrated, the output can be trimmed
to compensate for other Input/Output devices.
Conduct an Output Calibration using the
following procedure.
1) Select the Output Calibrate State of
Operation using the SELECT Key.
2) Use the or Keys to increase or
decrease the 0 or 4 milliampere output
signal. Press the ENTER Key to enter the
new value or to proceed to the 20
milliampere output level.
3) Use the or Keys to increase or
decrease the 20 milliampere output
signal. Press the ENTER Key to enter the
new value or to proceed to the Output
Calibrate State.
