OVERVIEW - Continued
In STANDARD TEMPERATURE MODE, the instrument
functions like a normal thermometer. In ITS™ Mode, the
instrument operates with the Intelligent Temperature
Stabilization™ feature. The 353 series instrument has a
unique feature to display temperature of item being
measured when the temperature has reached its final
stabilized temperature. The purpose of this feature is to
assist the user in determining when the final stabilized
temperature has been reached.The ITS feature is
dynamic, in that it operates continuously in real time. It
can be used in ITS Mode with the option of recording
stabilized temperature readings or simply as a
thermometer with ITS functionality. The MEMORY MODE
is for viewing ITS temperature data stored in memory
and you can scroll in both directions. The key
easily allows the user to select desired mode of
operation.
STANDARD TEMPERATURE MODE:
1) Press ON/OFF key to turn instrument ON/OFF.
2) Default temperature scale is Fahrenheit. To change
temperature scale, with instrument turned OFF,
press and hold key and then press key
to enter USER MODE
(NOTE: Display will show
“USEr”)
. Press key to switch between
Fahrenheit and Celsius
(NOTE: Display will toggle
between “F” and “C” icons on right side of
display with each press of the key).
Press
key to exit USER MODE to use instrument in
STANDARD TEMPERATURE MODE.
3) The instrument has an auto off feature that will turn
off unit after 10 minutes of non keypad activity to
conserve battery life. To disable auto off feature, with
instrument turned OFF, press and hold the MODE
key and then press key to enter USER
MODE. Press key to enable or disable auto off
feature. When active, the AUTO icon appears at the
top of LCD display. Press key to exit USER
MODE to use instrument in STANDARD
TEMPERATURE MODE.
ITS MODE (Intelligent Temperature Stabilization™):
1) To use ITS MODE, press to turn instrument ON. On
power up, the instrument is placed in STANDARD
TEMPERATURE MODE. Press the key to
select and activate the ITS function. The ITS icon will
appear at the top of the LCD when ITS MODE is
selected.
4) The instrument has an auto off feature that will turn
off unit after 10 minutes of non keypad activity to
conserve battery life. To manually turn instrument off,
press and hold key momentarily. To disable
AUTO-OFF feature, press and hold key and
then press key.
(NOTE: “AUTO” icon at top
of display will appear when AUTO-OFF feature is
active).
5) The resolution default setting is tenth degree. To
change resolution to whole degree, press and hold
key and then press key.
6) Press key to turn on backlight. When pressed,
the backlight will remain on for 5 seconds and
automatically turn off.
NOTE: USE OF BACKLIGHT WILL
SIGNIFICANTLY DECREASE BATTERY
LIFE DUE TO INCREASED POWER
REQUIRED FOR BACKLIGHT OPERATION
7) The instrument has a “HOLD” feature to capture the
current temperature reading on the display. To
activate the hold feature, press and release the
key. The current temperature reading will flash on the
display and the hold icon will appear at top of display.
Press the key again to return to STANDARD
TEMPERATURE MODE.

2) When ITS MODE is active, the display will show “- -”
while the temperature is changing (stabilization
seek mode). The final stabilized temperature reading
will flash on the display when reached. The ITS
temperature reading will remain flashing on the
display until the probe is removed or temperature
changes by approximately 5°F(3°C). When the
temperature changes, the instrument will return to
ITS stabilization seek mode and “- -” will be
displayed until the next stabilized temperature is
reached and that temperature reading will flash on
the display.
3) The user has the option of storing the ITS
temperature reading in memory. To store ITS
temperature reading, press key to store
reading. The display will show reading number
“r001-r250” and store reading in memory. Up to 250
readings can be stored in memory.
4) To return to STANDARD TEMPERATURE MODE,
turn unit OFF and back ON or repeatedly press
key until both ITS and MEM icons are
turned off at top of display.
MEMORY MODE:
1) To view temperature readings stored in memory, turn
instrument ON and press key to select
MEMORY MODE. When active, MEM icon will
appear at top of LCD.
(NOTE: WITH NO
TEMPERATURE DATA IN MEMORY, INSTRUMENT
WILL NOT ENTER MEMORY MODE.)
2) To view temperature data, press key to scroll
forward or key to scroll backward through
temperature data. The display will show reading
number “r001-r250” followed by the temperature
recorded.
(NOTE: TO ACCESS FAST SCROLL
MODE, PRESS AND HOLD KEY OR
KEY AND DISPLAY WILL QUICKLY SEQUENCE
THROUGH TEMPERATURE READINGS.)
3) The temperature data is a cyclical data system.
When scrolling through data, the temperature
readings will cycle through all readings either forward
or backward and then repeat readings when either
the first or last reading in memory is reached.
4) To clear temperature readings in memory, press and
hold both the and keys at the same
time until “CLr” is shown on display.
5) To return to STANDARD TEMPERATURE MODE,
turn unit OFF and back ON or repeatedly press
key until both ITS and MEM icons are turned
off at top of LCD display.
USER TIP
When temperature readings are cleared
from memory, there is no facility to
restore deleted temperature data.
Ensure that temperature data is not needed
before clearing memory contents.
