difference between first selected point and second selected point is
less than 25 ºC, “Wrong” message will blink.
• If the WRONG source is the difference between calibration points
increase the temperature of the vessel with hot water in order to be
acceptable.
• If the WRONG source is the temperature reading change the probe
and restart calibration.
If calibration cannot be performed contact Hanna Service.

possible to erase the calibration by pressing the Clear functional
key.
