Semi-automatic calibrations are operator initiated and can be performed using the Oxymitter 4000 keypad, HART handheld communicator/AMS software, or a remote contact. In addition, the calibration gases must be permanently piped to the Oxymitter 4000.
Oxymitter 4000 Keypad
A semi-automatic calibration can be initiated by pressing the CAL button on the Oxymitter 4000 keypad. For more information, refer to the Oxymitter 4000 Oxygen Transmitter Instruction Manual.
HART Handheld Communicator/AMS Software
A semi-automatic calibration can be initiated by connecting the HART handheld communicator, or AMS software, to the Oxymitter 4000 4-20 mA signal line and using the HART communicator keypad or computer keyboard to access the applicable calibration menu. Refer to the Oxymitter 4000 Oxygen Transmitter Instruction Manual or HART documentation for more information.
Remote Contact
A semi-automatic calibration can be initiated using a remote contact such as a customer's control system. The remote contact processes the calibration command on a PC and sends the signal to the Oxymitter 4000. For more information on remote-site calibrations, refer to the documentation for the system in use.
