” Power Button
The “ ” button turns the thermometer on or off. When the meter is in MAX/MIN record mode, the power off function is disabled.
(2) “[LIMITS]” Button (only Main display)
The limits function will alert the user when a meas- urement exceeds a specified limit. To set the limit val- ues, refer to limits function in the setup mode. Press the [LIMITS] button to activate the limits function; the word “LIMIT” should be displayed on the LCD.
When the value of the main display exceeds the Hi limit, the word “Hi” will be displayed and the ther- mometer will beep in a pulsed tone. If the value of the main display is lower then the Lo limit, the word “Lo” will be displayed and the thermometer will beep in a continuous tone To exit the limits function, press the [LIMITS] button.
(3) “ ” Button
The backlight function is represented by this button
“”. Pressing the button will turn on or off the LCD backlight. The backlight will turn off automatically after.
(4)“SAVE/READ” Button
The read data function works in conjunction with the save function in the shift mode, it is used for reading saved data. The save function can be activated in shift mode. Press the SAVE/READ button to read saved data; the word “READ” should be displayed on the LCD. To navigate around the save data table, press the overlay “SECOND” button until the “#” sign is dis- played on the second display. The location of the read pointer within the saved data table will be displayed. The arrow buttons on the overlay are used for scrolling through the saved data. Press the smaller arrows “ ” or “ ” to step through the data one at a time. Press the
larger arrows “ ” or “ ” to step through the data ten at a time. Pressing the overlay “ESC” button deac- tivates the read data function.
(5) “LOG/READ” Button
The read log function works in conjunction with the log function. It is used for reading logged data. The log function can be activated in the shift mode. Press the LOG/READ button to activate the log read func- tion; the word “READ” is displayed on the LCD. Press the overlay SECOND button to rotate through follow- ing display menus: T1, T2, GRP, and #. T1 and T2: Displays the T1 or T2 saved data. GRP: Displays the current group number. #: Displays the current location of the read pointer within a selected group. The arrow buttons on the overlay are used for scrolling through the data and groups. Press the smaller arrows “ ” or “ ” to step through the logged data or groups one at a
time. Press the larger arrows “ ” or “ ” to step through the data or groups ten at a time. To navigate the logged data and groups, press the overlay SECOND button until GRP appears in the second dis- play panel. Then select the group using the arrows.
Press the SECOND button again until the “#” sign is displayed. The location of the read pointer in the se- lected group will be displayed. Use the arrows to scroll through the data. Pressing the overlay “ESC” button deactivates the read data function.
(7) HOLD Mode (only Main display)
When HOLD mode is selected, the thermometer holds the present readings and stops all further measure- ments. To activate the data hold mode, press the HOLD button, and “HOLD” is displayed on the LCD. Pressing the HOLD button again cancels the function, and the instrument will automatically resume meas- urements.
(8) MIN/MAX with Time record Mode (only Main display)
The MIN/MAX function records the highest and low- est value recorded. It also calculates the average read- ing and the differences of MAX to MIN. Press MIN/MAX button to enter the MIN/MAX recording mode. The beeper emits a tone when a new minimum or maximum measurement is recorded. Press the MIN/MAX button again to cycle through the current readings: MAX: The highest measurement recorded. MIN: The lowest measurement recorded.
This mode works in conjunction with the hold func- tion, pressing the HOLD button will stop recording and measurements (Previously recorded readings are not erased). Press HOLD button again to resume re- cording and measurements. To prevent accidental loss of MIN, MAX and AVG data, the MIN/MAX function can only be cancelled by pressing and holding down the MIN MAX key for more then 2 seconds. The automatic
