in an interval frequency. 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 frequency.
In Limits function, on K or J Type, and with the scale of
temperature at °F, the reading counts should be times 10.
(ex: 2100°F means 21000 counts)
To exit the Limits function, press the [Limits] button.

Press the SAVE/READ button to activate the Read Data
function; the word “READ” should be displayed on the
LCD. To navigate around the Saved Data table, press the
overlay “SECOND” button until the “#” sign is displayed on
the second display panel. 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. Pressing the smaller arrow “
” or “
” retrieves the
next saved data. Pressing the larger arrow “
” or “
”
will retrieve the next ten saved data. Pressing the overlay

can be activated in the shift mode. Press the LOG/READ
button to activate the read log function; the word “READ”
should be displayed on the LCD. Press the overlay SEC-
OND button to rotate through following display menus:
T1, T2, GRP, and #.
T1 and T2: Displays the T1 or T2 saved value.
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 retrieve the next log data or
group. Press the larger arrows “ ” or “
” to retrieve
the next ten log data or groups. To navigate around the log
data and groups, press the overlay SECOND button till
GRP appears in the second display panel, and then select
the group using the arrows, then press the SECOND button
again till the “#” sign is displayed. The location of the read
pointer in the selected group will be displayed, and then 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 measurements. 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 measurements.
(
8) MIN/MAX with time record mode (only main
display)
The MIN/MAX function records the highest and lowest
value recorded, and it calculates the average reading, and
recorded. Press the MIN/MAX button again to rotate
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
through the current readings:
MAX: The highest measurement recorded.
MIN: The lowest measurement recorded.
MAX-MIN: The difference of the highest and the lowest
measurement.
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 than 2 seconds.
The Automatic Power Off function, and the power, C/F,
REL, SET, Hi/Lo Limits, TYPE, T1/T2 buttons are also
disabled.
(10) “T1/T2” button (MAIN display)

setup mode. Press the LOG button to activate the log
function; the indicator “LOG” and “MEM” will be dis-
played on the LCD. There are 16 groups that are used for
storing the log data, and each group uses 64 data slots. If

will automatically use the next group to store the following
data. A maximum of 1024 data can be saved in one log
session. Press the LOG button again to exit the data log
function.
(6) “CLR ?” button
The CLR function clears all the saved and logged data in

the relative value compared to the reference value.
Press “REL” button again to clear the reference value and
deactivate the relative value measurement function.
(8) “[APO]” button
