16 MAINTENANCE

Each OSP portable infrared thermometer has been factory tested and calibrated before shipment.

The calibration should be verified and re-adjusted if the instrument shows an error exceeding the declared specifications or when a critical active or passive component is replaced (either at the component level or at the board level).

OMEGA engineers will give prompt support for any request of assistance.

16.1Faulty operating conditions

During the start-up and measuring modes, faulty conditions of the instrument will be announced with coded messages. If the faulty condition is critical for the application, it is recommended to re-start the pertinent set-up procedure.

All errors which cannot be recovered without the user's knowledge, result in some system action to inform the operator via message and where possible to restore the system.

Restarting the instrument from -Power ON- may clear the error, but generally such messages are caused by hardware or software faults, which require the user's action.

Display	Error Type	Solution
Err 1	Internal EEPROM memory error	Contact technical support
Err 2	IR sensor reading error	Verify ambient temperature
		(from -5 to +55°C)
Err 3	Calibration data error	Recalibrate unit
OTC	No sensor connected at Tc input	Connect sensor
RJer	Cold-junction sensor reading error	Verify ambient temperature
		(from -5 to +55°C)

16.2Storage

If the instrument has been left unused for a long time, it is recommended to remove the batteries.

Store the instrument in the original package, at a temperature from -30°C to +60°C, with R.H. less than 90%.

If the instrument has been unused for a month check the battery voltage, and charge the Ni-MH batteries for at least 12 hours with the unit switched off.
