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.

16.1 Faulty 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)

16.2 Storage

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.
