CALIBRATION
The instrument has been calibrated for a particular
flammable gas mixture. Where any doubt exists the
instrument should be returned to GMI or an authorised
distributor for calibration.
Four methods of calibration are possible:
• Field Calibration. See APPENDIX B, FIELD
CALIBRATION for further details.
• Manual Calibration. The instrument can be linked
to a PC running GMI Manual Calibration software.
• Automatic Calibration. The GMI Auto Test Cali-
bration System allows calibration without manu-
ally changing gas cylinders. The system links to a
PC running GMI Workshop software.
• The GMI Instrument Management System (IMS)
provides all the facilities of the Auto Test Calibra-
tion System with the added feature of instrument
database management.
Note: The calibration systems above (hardware and
software) are manufactured by GMI. For more
details contact GMI or an authorised distributor.
