3) Set the engineering unit by pressing the
Key to toggle the unit between C (i.e.,
o
degrees Celsius) or F (i.e., degrees
o
Fahrenheit), and press the ENTER Key to
use the displayed engineering unit.
4) Confirm the displayed reading is STABL?
(i.e., stable) using either the YES or NO
Key. If the NO Key is pressed, the
TB84PH Advantage Series analyzer will
return to the Temperature Calibrate
State. For an unstable condition,
conduct one or more of the following
steps:
a) Wait until the temperature
stabilizes,
b) Check to see if the TB84PH
Advantage Series analyzer has
detected a Fault condition by
looking for the Fault icon on the
LCD. Interrogate the fault by
escaping to the Measure Mode
through the Exit to MEASURE Key
and the FAULT Info Key in that
order.
c) See Section 14, Troubleshooting.
5) If the reading was stable, enter the
temperature as the NEW VAL (i.e., new
temperature value) using the Key to
increment the blinking digit and the
Key to move to the next digit. Press the
ENTER Key to enter the new value.
6) Repeat steps 1 through 5 once the sensor
has been mounted in its final installed
location; however, use the process fluid
temperature as the NEW VAL.
Edit Calibrate State
The Edit Calibrate State allows a user to
manually adjust the sensor and temperature
slope and offset values. Though this function
may not be suitable for many applications,
this Calibrate State facilitates quick and
easy access to these calibration values for
troubleshooting purposes.
Conduct an Edit Calibration using the
following procedure.
1) Select the Edit Calibrate State of
Operation using the SELECT Key.
2) Edit the sensor PV SLP (i.e., efficiency)
