2.2 Display Min/Max Readings
The Portable Digital Thermometer will display the lowest and highest temperature readings measured by the temperature probe since the unit was turned on. For example, while the unit is on, the temperature being measured changes from 40º F to 100º F (4.4º C to 37.8º C), then
drops to 60º F (15.6º C). The display now shows 60º F (15.6º C). Press the MIN/MAX button. Dashes will appear, then the MIN value 40º F (4.4º C) for a few seconds, then the MAX value 100º F (37.8º C) for a few seconds, then back to the current probe temperature, 60º F (15.6º C).

The display will show the letters “CL” to indicate that the memory has been cleared. The Portable Digital Thermometer will then resume displaying the current probe temperature on the display, and begin to store a new set of MIN/MAX values. If the unit is turned off, MIN/MAX values will be cleared.
2.4 The “Hold” Function
To “freeze” the current temperature reading on the display, press the HOLD button once. The temperature displayed will not change while the hold function is active. The display will alternate showing the temperature, and the word HOLD to indicate the hold function is still active. To
return to normal mode, press the HOLD button once again.
2.5 Select Degrees C Display
The temperature scale is normally in degrees Fahrenheit. To display the temperature reading in degrees Celsius, press the ºF/ºC button. A small letter “C” will appear at the right side of the display to indicate readings in degrees Celsius.
