‘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.
