Important Notice (Must Read)
1. For batteryreplacement, it is a must to use a new and highquality CR2
lithium battery for replacement. Otherwise the instrument cannot
correctly estimate the battery life.
2. During replacing the battery, after the old battery is removed, the
instrument still has residual power. Wait until the residual power of the
instrument is completely exhausted, that takes about 5 seconds, and
you can see the whole LCD screen is off. Then you can install a new
battery. Otherwise the instrument will not recognize if a new battery
has been replaced. If the remaining battery power is not exhausted
and a new battery is installed, you can remove the battery again, and
wait until the LCD screen is completely off, and install the new battery
again.
3. After replacing the new battery, the first time connect the instrument to
the application software, the software will remind the user that the
battery has been replaced. Be sure to use a brand new battery.
4. After installing the battery, do not remove the battery, unless the
battery is exhausted or the remaining battery capacity is too low that
cannot complete the scheduled task.
5. The action of removing the battery and then putting the removed
battery back is equivalent to replacing the battery. The instrument will
assume that a new battery has been replaced and the battery life is
estimated with the new battery's power. In this case, the estimated
battery life is not accurate.
6. Do not replace the battery in a humid environment, because high
humidity air can enter the instrument through the battery compartment.
The moisture inside the instrument may affect the operation of the
electronics or cause rusting of the components.

5
7. When the instrument has just been used at low temperature
environment, do not replace the battery when the temperature of the
instrument has not returned to room condition. It is because the
relatively warm outside air will enter the instrument from the battery
compartment, which can produce moisture when the warm air meet
the cold parts inside the instrument that will adversely affect the
instrument. Therefore, before replacing the battery, wait until the
instrument returns to room temperature and remove the water from
the surface of the instrument.
8. The instrument has a built-in magnet that can be used to attach the
instrument to the flat iron surface. Do not place the instrument next to
the items, tools, or magnetic cards, etc. those will be affected by the
magnetic field.

the year.
16．When the symbol is displaying, it means that the displaying time is the
morning time.
17．When the symbol is displaying, it indicates that the displaying value is
the highest temperature that has been recorded. If the instrument is in the
Measurement Mode, then the displaying value is the highest measured
temperature value. If the maximum temperature value is higher than the
operating temperature range of the instrument, it will display the the
symbol.
18．When the symbol is displaying, it means that the displaying time is the
afternoon time.
19．When the symbol is displaying, it indicates that the displaying value is the

Reset Max and Min values
At measurement mode, maximum and minimum values can be reset.
When the maximum temperature value is displayed, press and hold the key for more
than 3 seconds to reset the maximum value. The digital zone will not display the
temperature value at this time, and the instrument will recalculate the maximum
value from the next measurement and display it again.

When the minimum temperature value is displayed, press and hold the key for more
than 3 seconds to reset the minimum value. The digital zone will not display the
temperature value at this time, and the instrument will recalculate the minimum
value from the next measurement and display it again.
Note:
The instrument does not calculate the maximum and minimum values in wait
mode ( symbol displaying).
In the record mode ( symbol displaying) and in the end mode (
symbol displaying), the maximum and minimum values cannot be reset. The
maximum and minimum values in these modes refer to the highest and lowest
values ever recorded, which are part of the recorded data and cannot be reset.

Instrument Working Mode
INNO 320 has 4 working modes:
Wait mode
In wait mode, the instrument has been scheduled to record temperature. It is
waiting to enter to record mode and start temperature recording. The
symbol is displaying on the screen.
Users can set 3 methods to start recording:
1. Key start: Press and hold the key for 3 seconds, instrument will enter
record mode.
2. Time start: Set the time to start temperature recording. When the pre-
set time is reached, the instrument will enter record mode.
3. Temperature start: With temperature-rise start method, when the
measured temperature is higher than or equal to the pre-set value, then
the instrument will enter record mode. Similarly, with temperature-drop
start method, when the measured temperature is lower than or equal to
the pre-set value, then the instrument will enter record mode. In addition,
temperature-rise start and temperature-drop start method can be
enabled simultaneously.
Record mode
In record mode, instrument will record the measured temperature,
symbol is displaying in this mode.
The recording interval can be set between 10 seconds to 24 hours.
The instrument can stored up to 130,599 temperature values.
The upper and lower limit alarm functions can be set. When the recorded
temperature reaches the upper limit or reaches the lower limit, the
corresponding or symbol is displayed. If both the upper and lower
limits have been reached, both the and symbols will be displayed

17
simultaneously. If the LED alarm function is enabled, the red LED will flash
every 10 seconds after alarm was triggered.
Three recording method can be set:
1. Set a number of temperature values to be recorded, when the recording
amount was reached，recording will stop, instrument will enter end
mode.
2. Set a time period for recording，the recording start time and end time
should be set. When end time was reached, recording will stop,
instrument will enter end mode.
3. Cycle recording. Instrument will keeping recording data, when the
memory was full, the latest measured value will be recorded, and the
oldest value will be discarded. User can stop the recording by the
application software.
Note: If cycle recording method was used, the maximum and minimum
temperature values displayed on the instrument screen refer to the
highest and lowest values recorded by the instrument, not just the
highest and lowest values among the 130,599 temperature values
stored in the instrument. Therefore, the maximum and minimum values
displayed may no longer exist in the instrument's record.
End mode
In this mode, symbol is showing on the screen. Instrument was
completed the scheduled recording task, recording was stopped, but it will
still measure temperature and display it on the screen.
Measurement mode
In this mode, instrument will no record data, it is used as an accurate
temperature measuring instrument instead.
In this mode, when displaying maximum temperature value, the Max value
can be reset by pressing and hold the key for more than 3 seconds.
In this mode, when displaying minimum temp0erature value, the Min value
can be reset by pressing and hold the key for more than 3 seconds.

If LED alarm function was not enabled, user can observe whether or
symbol appears on the display to determine whether the upper and lower limit
values have been reached. If symbol appears, it means the battery is
running out.
LCD backlight
INNO 320 display has backlight function.
The backlight can be set to 3 working mode
1. Backlight function always enabled. Whenever the key is pressed,
backlight will be on for 10 seconds, so the display contents can be
clearly seen in a dark environment.
2. Auto backlight function. If the environment is dark, the backlight will be
on for 10 seconds when the key was pressed, so users can see the
display clearly. However, if it is under a well-lit environment, the
backlight will not be turned on even the key was pressed. This can avoid
unnecessary turning on of the backlight and save battery power.
3. Backlight function disabled. The backlight will not be turned on under
any circumstances.
Note: When the temperature is below -30 °C, the backlight function will be
