Temperature calibration
NOTE: For the temperature calibration, separate, accurate test plugs (25 °C and 45 °C) are
needed.
A test set of two plugs is available from GE Healthcare, order code 884515.
Calibrate the temperature when the measured test values deviate more than ±0.1 °C, and always
after LM-STP board replacement.

Verify that both pressure values in the prompt field match the manometer reading. If not,
adjust by turning the ComWheel. When the values of the pressure bar and the manometer
are equal, press the ComWheel to confirm the calibration. The message "Calibrating" will
appear in the NIBP digit field. After a few seconds it is followed by "Calibrated", which
means that the calibration has succeeded, and the new calibration data has been saved
into EEPROM.
To set the protection on:
Push the calibration switch to the bottom and keep it at the bottom. Select "Protection"
ON, push the ComWheel and release the switch.
Switch off the monitor and then turn it on. Then perform Calibration Check (see the
preceding page) to verify the new calibration.
Enter ESTP: STP service menu.
(Main Menu - Monitor Setup - Install/Service (password 16-4-34) - Service View
(password 26-23-8) - Modules).
Enter Calibrations menu.
Press the protect button at the bottom of the monitor and choose OFF in protect mode.
Release the button.
Choose Calibrate T1 in the service view.
Insert calibration plug (25 °C) into Temp connector.
Push the ComWheel two times.
Insert calibration plug (45 °C) into Temp connector.
Push the ComWheel two times.
