” 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

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

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

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. MAX-MIN: 
The difference of the highest and the lowest measure-
ment. AVG: The average values of the measurements. 
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 
power-off feature, and the power, °C/°F, REL, SET, 
Hi/Lo Limits, TYPE, T1/T2 buttons are also disabled.
