There are three operation modes-Normal, Shift, and
Setup Mode.
NORMAL MODE:
This is the default mode, the operating functions for
the normal mode are printed on top of each button in
white.
SHIFT MODE:
The operating functions for the shift mode are printed

Press the “ ” key for more than two seconds to start
wireless function. Press “ ” for another two seconds
to stop wireless function. The wireless mode will shut
down if there is no wireless signal for two minutes.
SET CH/ID to 00,00 by pressing “T1-T2” key and
“
” power key for more than six seconds when the
meter with the meter powered down. The second dis-
play will show 00, which means that the channel and
ID has been set to 00.
To check the channel and ID of the meter:
When the meter is off press “
” key and “
” for
5 seconds. The LCD’s main display will show channel
number, the second display will show ID number.
2. NORMAL MODE
The following functions can only be used in the normal
mode.
(1) “ ” 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
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. 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 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 power-off feature, and the power, °C/°F,
REL, SET, Hi/Lo Limits, TYPE, T1/T2 buttons are
also disabled.

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.

The save function stores the T1, T2 data in a nonvola
tile memory. Press the SAVE button to save the
rent data, the word SAVE is displayed to indicate
data has been saved. The built in memory can store
to 128 data. The data can be read using the read
