Would usually be held by a Calibration Engineer, who would come in to the customer’s premises on request. Would be used flat on a table connected by RS485 cable to the Engineer’s laptop.

The Calibration Tool interacts with the Calibration Module and acts as a virtual display and keyboard.  When a transmitter is to be calibrated it must be placed on the Calibration Module cradle. The Engineer then puts the Calibration Module into calibration mode via the calibration tool software.

When a Transmitter is put into calibration mode it sends messages to the System to identify that it is in calibration mode to stop alarms. When the transmitter is taken out of calibration mode another message is sent to the System that it is back in normal mode.  If the sensor for some reason has not been taken out of calibration mode in 6 hours then an alarm is sent to warn that the transmitter is still in calibration mode.

Once the unit has gone through its calibration routine the Engineer will take it out of calibration mode.  All calibration details will be held in the Transmitter itself, so no adjustments to the Notion Pro data base are required.
