• °C/°F user-selective.
• MAX/MIN with elapsed time, AVG, REL, HOLD function.
• TIME setting, REL setting.
• Warning beeper with Hi/Lo setting.
• Resolution 0.1°C to 0.2°F.

OPERATING INSTRUCTIONS

Power Button
The “ ” key turns the thermometer on or off. In the SET mode cannot be powered off. Exit SET mode to power off.

APO function mode
Press “ ” power key for more than 4 seconds to disable the auto-power function.
The display will show “APO OFF”.

“°C/°F” Selecting the Temperature Scale
Readings are 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/°F” key.

“ ” Mode (only Main display)
Press this key to enter the Data Hold mode, the “HOLD” annunciator is displayed. When HOLD mode is selected, the thermometer holds the present readings and stops all further measurements. Press the “ ” key again to cancel HOLD mode and resume measurements. In the MAX/MIN recording mode, press “ ” key to stop the recording. Press “ ****” key again to resume recording. (Previously recorded readings are not erased).

Backlight function mode
Press the “ ****” key for more than two seconds to turn on the backlight. Press the key again for more than two seconds to turn off the backlight. The backlight will switch-off automatically after 30 seconds.

“T1 T2/T1-T2” Main Display Input Selection
The input selection indicates which input is selected for main display; T1 thermocouple, T2 thermocouple or  the difference between the two thermocouples (T1-T2), when the thermometer is turned on, it is set to T1.

“K/J” Main display Input Thermocouple Type Select
The “K/J” key selects the T1 thermocouple type, when the main display is showing T1. When the thermometer is turned on, it is set to the type selected when the thermometer was last turned off.

“MAX/MIN” With Time Record Mode (only Main display)
Press “MAX/MIN” key to enter the MAX MIN Recording mode, (displays the Maximum reading with time, Minimum reading with time and Average reading stored in record mode). In the this mode the automatic power-off feature is disabled and “ POWER” key, “°C/°F” key, “REL” key, “SET” key, “Hi/Lo LIMITS” key and main display
“T1 T2 T1-T2” key, “K/J” key are disabled. The beeper emits a tone when a new minimum or maximum value is recorded.
Press “MAX/MIN” key to cycle through the MAX, MIN and AVG readings. If an overload is recorded, the averaging function is stopped. In this mode, press the
“HOLD” key to stop the recording of readings, all values are held, press again to restart recording.
To prevent accidental loss of MAX, MIN and AVG data, this mode can only be cancelled by pressing and holding the “MAX/MIN” key for 2 seconds. All recorded readings are erased.

“REL” Relative Mode (only Main display)
Press the “REL” key to enter the relative mode, zero the display, and store the displayed Reading as a reference value. REL is shown on the display. Press “REL” key again to exit the relative mode. The relative reference  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 and than press “SET” key use the entered relative value as a reference value. Press “REL” key again to exit the relative mode. In the relative mode, the value (can not >±3000.0 counts) shown on the LCD is always the difference between the stored reference and the present reading.

“Sec. Minu.” Selecting the Time scale
Press this key to display the elapsed time on the third display in either hours and minutes or minutes and seconds. When the thermometer is turned on, it is set to seconds. To change the time scale, press “Sec. Minus.” key. Maximum elapsed time reading is 100 hours. If 100 hours is exceeded, the elapsed time resets to zero.
