If the Temperature Compensation Override is set to ON
(see section 6.11), the Shark cannot calibrate the
temperature sensor. This display will appear to alert the
user to the condition.
If the calibration did not appear
to be correct, press the
key which will return back to the
Temp Calibration menu.

This will store the calibration
data and return back to the
Temp Calibration setup so
the user can select another
function.
Use the and to adjust
the reading until it agrees with the
known temperature of the probe
Press the key to accept the
reading and move to the store function
"T FACTOR SHIFTED" will be
displayed for 5 seconds to indicate that
the temperature sensor has been
calibrated.
The Shark will then move to the store
function.
The controller displays the current probe
temperature.
If this incorrect, the controller can be
adjusted to compensate.
Press the key once
which will move the cursor

Press the key once
which will move the cursor
over the least significant digit
of the temperature display.

Temperature Calibration
In most cases, the factory temperature calibration is accurate enough to ensure correct temperature readings. However, in some circumstances, the user
may wish to ensure the temperature sensor is calibrated accurately, especially when operating at the extreme end of the conductivity cell temperature
operating range, or where the temperature compensation is critical to correct process readings.
This menu allows the user to calibrate the temperature anywhere within it's range.
Be aware, that the conductivity reading is affected by the temperature reading (due to the temperature compensation) so accurate temperature
calibration is vital to obtaining accurate conductivity readings. If the user is unsure of the calibration test fixture, then it would be best to leave
the temperature calibration at it's factory setting.
Be sure to allow the temperature of the cell to stabilize before attempting to calibrate the temperature sensor, this may take a significant amount of time as
the sensor is buried behind a protective layer of epoxy which will cause some delay.
