5 Settings Parameters
5.1 Access Code 1 - Calibration
WARNING!
During a calibration, the detectors that are being calibrated are set to inhibit. Therefore a safe
operation of the area usually monitored by the now inhibited detectors must be ensured by other
means.
Entering the menu keeps outputs as follows:
• Alarms are inhibited
• 4/20 mA output is set according to Access Code 2, P2.
• Failure LED and failure relay active
WARNING!
ATEX mode is active then 4-20 mA output follows setting made in Access Code 4, P 20.
Step Function
P1
Zero Calibration
Adjusting the clean air value
P2
Span Calibration Gas Concentration
Possible settings: 2 % - 100 % of measuring range, default 50 %
P3
Span Calibration
(Apply calibration gas with a concentration set at P2 in the detector).
Confirm after value is stabilized
P4
Display Actual Gas Concentration
(detected by the detector after the calibration)
P5
Display Full Scale Detector Signal at Calibration (depends on connected detector / trans-
mitter)
It displays Ux value (mV) for passive detectors or value of full scale signal (mA) for transmit-
ters achieved during last calibration procedure.
P6
Set Time Interval between Calibrations Notification
Possible settings: 0-999 days, default: 0 (disabled)
CAL symbol starts blinking if calibration interval is reached.
P7
Enable 4-20 mA Transmitters Calibration
Possible settings: A: enabled, nA: disabled, default: nA
If enabled, then zero (4 mA) and span (20 mA) calibration signals must be within the limit
interval ± 10% from the measured value. Otherwise E1 error is displayed.
