In the MIN MAX record mode can not power off, must leave MIN MAX record mode then power off. 2 5 °C °F Selecting the Temperature Scale Readings is displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). When the thermometer is turned on, it is set to the temperature scale that was in use when the thermometer was last turned off. To change the temperature scale, press the °C or °F key.
6 MIN MAX record Mode Press MIN MAX key to enter the MIN MAX Recording mode, (displays the Maximum reading, Minimum reading, "MAX-MIN" reading and Average reading stored in record mode). In the this mode the automatic power-off feature is disabled and key and all function key are disabled.The beeper emits a tone when a new minimum or maximum value is recorded. Push MIN MAX key to cycle through the MAX, MIN, MAX-MIN and AVG readings.
10 REL Relative mode (only Main display) Pressing REL key to enter the Relative mode, zero the display, and store the displayed Reading as a reference value and annunciator REL is displayed. Press REL key again to exit the relative mode. The relative value can also be entered by the user. (See "SET mode" later in this manual.) When the desired Relative value has been entered, press REL key to enter the Relative mode, press SET key use set Relative value as a reference value.
(Press ENTER key can escape Lo Limit value set mode), _ = = =.= is displayed (the ".=" is displayed when you set up the fourth number), Lo Limit value is entered via overlay numbers, when you want to get negative values push (- 0) key for end of numbers, then press overlay ENTER key, stored the Lo Limit value and exit set mode. 3. In the SET mode, the value can not >±2000.0 counts.all value will be memorized until yor reset it.
