Teledyne TED 200-T Instruction Manual page 31

The BATT TEST control of the TED 200-T immediately determines if the
batteries need replacing. The TED 200-T should momentarily be removed from the
application area and be checked for calibration and sensor integrity. If the TED 200–T
can be calibrated, the unit can be assumed to be in good working order and capable of
providing readings to specification. If, after reinstalling the TED 200-T, the discrepancy
in oxygen readings persists, the problem is most likely elsewhere (i.e., flow blockage,
primary device error, etc.). Further investigation should be made until the discrepancy
in readings is resolved.
If it is found that replacing the sensor and/or batteries does not give proper
calibration results, the troubleshooting section of this manual should be consulted.
