Calibrating your digital thermometer
When you first open the probe of your thermometer, you will be delighted to see the display activate automatically. EXCELLENT, you will say, the battery is fitted and I'm ready to go!!
Although your K & H G digital thermometer is acurate from the first use, there's nothing like going for absolute precision through calibration.
Using crushed ice, fill to a couple of inches from the top of a glass.
Fill the glass with cold water. Ensure there is enough ice to reach the bottom of the glass. Add more crushed ice if neccessary.
Using the probe of your thermometer, stir the iced water.
Leave the iced water to settle for a couple of minutes.
Immerse the probe of your thermometer into the water, ensuring it doesn't touch the bottom or sides of the glass. Press and hold the CAL button for 2-3 seconds.
The display first shows 'CAL' and then reverts to the temperature reading.
As Bruce Forsyth used to say, 'That's all there is to it!!'
You will now have your digital thermometer perfectly calibrated giving you 'spot on' temperature checking, every time.
