3.The thermometer should be stored at –20 to +65 oC (-4 to 149 oF).

EMC/RFI: Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.

Troubleshooting

‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the range of the instrument, ‘Hi’ when higher than +110oC (230°F) and ‘Lo’ when

lower than –33oC (-27°F).Please select target within specifications. If a malfunction still exists, please contact the nearest retailer.

‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient temperature. ‘Er3’ is displayed when the ambient temperature

exceeds –10 oC (14°F) or 50oC (122°F). The thermometer should be

allowed plenty of time (minimum 30 minutes) to stabilize to the working/room temperature.

For all other error messages it is necessary to reset the thermometer. To reset the thermometer, wait for the instrument power off, remove the battery and wait for a minimum of one minute, reinsert the battery and turn on. If the error message remains please contact a qualified service technician.
