8. Calibration
The monitor has been calibrated for particular gases. Where any doubt exists, return the monitor to
an authorized distributor for calibration.
WARNING: ONLY AUTHORIZED PERSONNEL MAY CALIBRATE THE
MONITOR.
Three methods of calibration are possible:
• Field - using the monitor’s Field Calibration feature.
• Manual - using FlexiCal Plus software.
• Automatic - using GDUnet station or FlexiCal Plus software.
8.1. Calibration Validity
Calibration validity is the responsibility of the user. Under normal operating conditions, a 12 month
period can be expected. However this is not guaranteed, as the precise application of the product
is unknown to Teledyne GMI. Individual codes of practice may dictate shorter periods.
Regular checking establishes a pattern of reliability and enables the calibration check to be
modified in line with operational experience. The higher the risk, the more frequently the calibration
should be checked.
8.2. Field Calibration
Note: Field Calibration is an optional feature that can be enabled during the monitor
procurement.
This feature allows simple calibration in the field without the use of the automatic and manual
calibration set-ups.
The following is required to perform field calibration:
• Calibration test gases
• Demand flow regulator
• Sample tubing
To perform field calibration:
1. If a field calibration mode is available, the
FC
symbol will flash on the information screen. Press
B4
to start the process.
