Operating Instructions
5. Calibration
• Press ON/OFF button.
• Put the instrument for 3 minutes into a bowl with ice water until the
temperature does not change anymore (±2°C).
• How to produce ice-water: Fill up a thermos bottle with crushed ice. Than
fill cold water into the thermos bottle up to the top, so that no air will be
in the bottle. After approximately 30 minutes the ice water has reached a
temperature of 0°C (+0.1°C). Depending on the quality of the thermos
bottle the temperature stays constant up to 24 hours.
• Note that two-thirds of the length of the probe is immersed in the ice
water.
• Press and hold °C/°F button (3 sec.) to get into the calibration mode.
• CAL appears on the display.
• Wait until 0°C (±0.5°C) appears on the temperature display.
• Hold °C/°F button, until 0°C appears on the display.
• The instrument is now calibrated.
• Stop pressing the °C/°F button to return in normal mode.
6. Battery replacement

• Use alkaline batteries only. Observe correct polarity. Low batteries should
be changed soon to avoid the damage resulting from a leaking battery.
Batteries contain harmful acids. Wear protective glasses and gloves when
