save function in the shift mode, it is use for reading
saved data. The save function can be activated in shift
mode. Press the SAVE/READ button to activate the
read data function; the word “READ” should be dis-
played on the LCD. To navigate around the save data
table, press the overlay “SECOND” button till the “#”
sign is displayed on the 2nd display panel. The location
of the read pointer within the saved data table will be
displayed. The arrow buttons on the overlay are use for
scrolling through the save 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 “ESC”
button deactivates the read data function.
(5) “LOG/READ” Button
The read log function works in conjunction with the
log function, it is use for reading the log data. The log
function 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 SECOND 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 use for scrolling through the data and
groups. Press the smaller arrows “ ” or “ ” will
retrieve the next log data or group. Press the larger
arrows “ ” or “ ” will retrieve the next ten log
data or group. To navigate around the log data and
groups. Press the overlay SECOND button till GRP
appears in the 2nd display panel, and then select the
group using the arrows, then press the SECOND
button again till the “#” sign is displayed. The loca-
tion 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 deac-
tivates the read data function.
(6) 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 in-
strument will automatically resume measurements.
(7) 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 measurement.
AV G : The average values of the measurements. This
mode works in conjunction with the hold func-
tion, pressing the HOLD button will stop the
recording and measurements (Previously rec-
orded readings are not erased). Press HOLD
button again to resume recording and measure-
ments. 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.
(8) “T1/T2” Button (Main display)
The input selection button [T1/T2] selects the input for
the main display panel, T1 thermocouple or T2 ther-
mocouple. 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.
(9) “T1/T2” Button (2nd display)
The input selection button [T1/T2] selects the input for
the 2nd display panel, 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.
(10) “T1-T2/TIME” Button (3rd display)
The input selection button [T1/T2] selects the system
time and date, or the differential between the two
thermocouples (T1-T2) for the third display panel.
Press the T1/T2 button to switch the display options.
When meter is turned on, it is set to the display that
was last in use.
SHIFT MODE
The following functions can only be use in the shift mode.
(1) “°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.
(2) “SAVE” Button
The save function stores the T1, T2 data in a nonvola-
tile memory. Press the SAVE button to save the current
data, the word SAVE is displayed to indicate the data
are saved. The build in memory can store up to 128
data. The data can be read using the read function in
the normal mode.
(3) “LOG” Button
The data log function continuously records the data
according to a specified time interval. The time interval
can be set using the interval time setup function [INVT]
in the set up mode. Press the LOG button to activate
the log function; the indicator “LOG” and “MEM” will
be displayed on the LCD. There are 16 groups that are
use 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
can be saved in one log session. Pressing the LOG
button again to exit the data log function.
New
So the total 16 groups can be stored up to 1024 data in
the meter. The data sending to pc will be stacked in one
session if the log function continues to use up the 1024
data.
The meter will stop recording if the 1024 capacity is
used up. If the user starts recording the data and stop
recording, and then start recording and then stop re-
cording again, this way will be presented to pc in two
sessions respectively in the pc.
(4) “CLR” Button
The CLR function clears all the saved and logged data
in memory. When the CLR button is pressed, indicator
“MEM” is displayed and the “CLR” word on up-
per-right of LCD will blink. Pressing “ENTER” button
printed on the overlay in white word to clear all saved
and logged data or “ESC” button to exit this function.
(5) “REL” Button (only Main display)
The relative value function can be use for comparing
the saved reference value with other measurements.
Press the “REL” button to store the current measure-
ment as the reference value, and the “REL” should be
displayed on the right part of the LCD. The next meas-
urement will display the relative value compared to the
reference value.
Press “REL” button again to clear the reference value
and deactivate the relative value measurement func-
tion.
(6) “[APO]” Button
Press the [APO] button to trigger “Auto power off”
function on or off. In this function, the indicator
“APO” is shown at the upper left panel of the LCD.
When APO (Auto power off) is enabled, it will auto-

button will change the thermocouple type for both dis-
plays.
(8) “TYPE” Button (Second)
Press this button to change the type of thermocouple in
the 2nd display (K/J/T/E/R/S/N). If the inputs of the
main and 2nd display are the same, then pressing this

plays.
SETUP MODE
The following functions can only be use in the setup mode.
(1) “[Limits]” Button (Hi/Lo limit setting) and
Mini DIN output
Press the LIMITS button to enter the Hi/Lo Limit setup
function, the “LIMIT”, “HI”, and main display will
blink on the LCD, and the previous settings are dis-
played. Press the number button printed on the overlay
in white word to set Hi or Lo limit value. The resolu-
tion of Hi/Lo limit setup is 1 count. The button “-”
(same button as the ESC) can be use to set negative
values. Setting is from left to right digit. Press the
“ENTER” button to confirm each setting. There is a
Mini DIN accessory on the top of this meter that is use
for outputting Hi/Lo signal (Refer to figure 1). When
the alarm function is enabled, connect the voltage,
about 5-30V between “Pin_5” and “Pin_6” (refer to
figure 2 and 3) that can initiate the Hi/Lo function of
Mini DIN. The bias network of the meter establishes a
drain current, which is the independent magnitude of
the external power supply voltage range from 5Vdc to
30Vdc @5mA.
