” 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 af- ter.
(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 function; the word “READ” is displayed on the LCD. Press the overlay SECOND button to rotate through following display menus: T1, T2, GRP, and #. T1 and T2: Dis- plays the T1 or T2 saved data. GRP: Displays the cur- rent 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, and it 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 rotate through the current readings: MAX: The highest measurement recorded. MIN: The lowest measurement recorded.
This mode works in conjunction with the hold function, pressing the HOLD button will stop the recording and measurements (Previously recorded readings are not erased). Press HOLD button again to resume recording 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
(10) “T1/T2” Button (Main display)
The input selection button [T1/T2] selects the input for the main display, T1 thermocouple or T2 thermocou- ple. Press the T1/T2 button to switch between the two inputs. When meter is turned on, it is set to the display that was last in use.
(11) “T1/T2” Button (Second display)
The input selection button [T1/T2] selects the input for the second display, T1 thermocouple or T2 thermo- couple. Press the T1/T2 button to switch between the two inputs. When meter is turned on, it is set to the display that was last in use.
(12) “T1-T2/TIME” Button (Third display)
The input selection button
3. SHIFT MODE
The following functions can only be used in the shift mode.
(2) “°C/°F” Button
Press the °C/°F button to select the temperature scale, readings can be displayed in Celsius (°C) or Fahrenheit (°F). When the thermometer is turned on, it is set to the temperature scale that was last in use.
(4) “SAVE” Button
The save function stores the T1, T2 data in a nonvola- tile memory. Press the SAVE button to save the cur- rent data, the word SAVE is displayed to indicate the data has been saved. The built in memory can store up to 128 data (HH806U)/256 data (HH806AU). The data can be read using the read function in the normal mode.
(5) “LOG” Button (HH806U)
The data log function continuously records the data according to a specified time interval. The time inter- val can be set using the interval setup function [INVT] in the set up mode. Press the LOG button to activate the log function; the indicators “LOG” and “MEM” will be displayed on the LCD. There are 16 groups that are used for storing the log data, and each group uses 64 data slots. If the current log session exceeds 64 data, the log function will automatically use the next group to store the following data. A maximum of 1024 data point can be saved in one log session. Press the LOG button again to exit the data log function.
