2. Program
Activates or deactivates the internal buzzer of the MX
43.
Allows for the modification of detector tags previously
programmed via COM 43.
Allows for the modification of detector alarms
previously programmed via COM 43.
Configuration of Port RS485 (speed, parity, stop bits,
slave number). This configuration is only useful if the
MX 43 is equipped with the RS485 communication
card.
3. Calibration
If the measurement cell has changed, it is important to declare this
through a menu no. 5 Cell change.
1. Detector select.
This menu enables the selection of detectors to be calibrated (calibration from
MX 43 or on the detector).
Display of information described by the COM 43 application: i.e.,
measurement range, gas detected, current detector ID and its type.
Display for the current detector:
■ Last passed calibration: Date and time of the last calibration
carried out and completed.
■ Last sensor replacement: Date and time of last cell change.
■ Wear rate: Relation between the value of the standard gas and the
value read (sensitivity measurement). A wear rate in excess of 100%
entails a sensor replacement.
Display of the address (digital detector) or line number (analog detector)
to which the detector is connected.
Selecting the detectors to be calibrated:
■ Select one or several detectors using the previous detector or next
detector keys.
■ On pressing the Select key, press Cal gas to enter its value by
means of the ↑↓ keys. Validate by pressing Enter.
Note: Only analog detectors that are not equipped with a local
display can be calibrated from the MX 43 controller. For the other
detectors, the menu “Sel. Detector” only makes it possible to put
them in calibration mode so that they do not activate alarms during
their manual calibration.
■ Press Escape to launch the procedure of recording the
measurements on the detectors to be calibrated. Proceed to
paragraph “2 Recording”.
Display the calibration gas.
