‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the settings of HAL and LAL.
「 」
」
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient temperature. ‘Er3’ is displayed
when the ambient temperature exceeds 0
o C (32°F) or +50 o C (122°F). The thermometer should be allowed plenty of
time (minimum 30 minutes) to stabilize to the working/room temperature.
「 」
Error 5~9 , for all other error messages it i s necessary to reset t he thermometer. To reset it, turn the instrument off,
