Calibration Hints
Nominal Stability vs. Full Stability
To meet the criteria for a valid calibration point, the change (delta) in sensor response is
monitored over time. The controller is looking for the calibration solution temperature
and the sensor readings to settle over a specific time period. The criteria for Full
Stability are designed to meet the published specifications. The criteria for Nominal
Stability are designed to shorten the calibration time when an approximate calibration is
acceptable.
Factory Recalibration
Proper maintenance can improve your results and extend the life of the instrument.
When the instrument is overdue for a factory recalibration, the Service Needed
icon
will appear on the display.
l
Factory recalibration of the Level TROLL Instruments should be performed
annually.
