SAFETY INSTRUCTIONS
2 DEVICE COMPONENTS
2.1 Use
The devices have a male USB plug and on-board integrated software in PDF format to download and configure the data
logger without additional software.
2.2 Applications
The data logger is ideal for temperature and humidity monitoring of the sensitive product storage, for example in the food
industry or pharmaceutical domain. It allows the monitoring of temperature and humidity in refrigerators, cold rooms and
food trucks.
Therefore, the device guarantees a traceability all along the cold chain. And at any moment, easily and quickly edit and
produce a PDF data report.

4.4 Data logger configuration with the on-board integrated PDF file
The class 120 data loggers have an on-board integrated PDF file for quickly and easily configuring the data logger.
Therefore, you can directly configure your data logger without utilizing the KILOG software.
Required configuration: to open this document, you need to use ONLY the “Adobe Acrobat Reader 9®”
program (or higher), freely downloadable, to read PDF format documents. Ensure you have installed it before
starting.
➢ Plug the class 120 data logger to the computer USB port*.
The following window opens:
➢ Click “Open folder to view files”.
Wait a few seconds (according to the dataset number of points), and a volume appears.
➢ Double-click “Configuration...” PDF file

Recorder
Active screen: tick “Yes” to activate the screen display or “No” to deactivate it.
Management DST: for an automatic management of DST, tick “Yes” or tick “No” to
deactivate it. If you choose “Yes”, the “Next time change” fields become accessible. Dates
and times of the next time change are proposed by default. You can modify them: click “Date”
field then to display the calendar. Select the required date. Click “Hour”
field to modify the time on which the next time change will be applied: the
time format is 00:00. On the last field, click and choose “+1h” to add an
hour or “-1h” to subtract an hour. The date and time change will be applied
on the required date and time and will add or subtract an hour.
Recording
Interval: in the “Interval” field, enter the required interval duration between two
measurements, then select the unit (minutes or hours).
Start type
- Tick “Button” for a start type by button.
- Tick “Date” for a start type by date: enter the required date and time of the start. Click
“Start date” field then click to display the calendar and select the required date, or write it
manually, respecting the date format selected previously.
Stop conditions
Stop type
Select the required stop type:
- The stop by date is available only if the start type by date has been previously chosen. If you choose
“Date”, inform the required stop date and time in the “Stop date” field: click to display the
calendar then select the required date, or write it manually respecting the date format selected
previously.
- Stop by duration: enter a recording duration. Fill in the “Days” and “Hours” fields.
- Stop by number of items: enter the required number of measurement before the dataset
stops. Fill in the “Number of items” field (between 1 and 50 000 points).
- “Total memory”: record continuously up to 50 000 points before the dataset stops.
- “Loop” allows to record the values continuously and once the memory capacity is reached,
the last recorded values overwrite the first.
- “Stop by button”: tick “Yes” to authorize a stop by button. Therefore, push the data
logger OK button for 3 seconds to stop the measurement dataset. To not authorize it, tick
“No”.
The stop by button can not be deactivated if the chosen stop condition is “Loop”,
“Total memory” or “Number of points”.
Channel parameters
Temperature (KT 120 and KH 120) and humidity (KH 120 only)
- Choose the temperature measurement unit: tick the “°F” or “°C” box.
- Active channel: tick “Yes” to activate the channel or “No” to deactivate it.
- Active alarm: tick “Yes” to activate the alarm or “No” to deactivate it.
If the alarm is activated, fill in the “High” and “Low” fields to set the alarm threshold. Inform
the “Delay” field in number of points. According to the measurement interval previously
configured, the duration is automatically actualized. Example for a setting with an interval of 1
minute and a delay in number of points for the high threshold of 5: the delay duration will be 5

➢ When the configuration is complete, click to confirm.
➢ Chose the location to save the configuration: to use this configuration for the next dataset, save the configuration
directly on the data logger on “Removable disk”.
Check that the dataset is completed to ensure the new configuration will be taken into account.
A message will ask to overwrite the existing file.
➢ Click “Yes”.
➢ To use this configuration later for another dataset, or to configure another device, you can save it on the computer.
To recover it later, click then select the file under “.xdp” format,click
to use it with the next dataset.
4.5 Data logger download with PDF report edition
➢ Plug the class 120 data logger to the computer USB port*.

5 DEVICE MAINTENANCE
5.1 Replace the battery
With 500 days to 3 years* battery life, the data logger guarantees long-term measurement.
To replace the battery:
1. Unlock the battery hatch with a flathead screwdriver or a coin.
2. Turn left until the marker aligns in front of the opened padlock symbol.
3. Keep turning until the hatch rises.
4. Replace the battery (button battery CR 2450**) in such a way the + pole is visible.
➢ Replace the battery hatch with the indicator in front of the opened padlock and close it by turning it towards the
right, in order to match the indicator with the closed padlock.
Only use trademark or high quality batteries in order to guarantee proper battery life.
After the battery replacement, the device must be reconfigured.
5.2 Device cleaning
Please avoid any aggressive solvent.
Please protect the device from any cleaning product containing formaldehyde that may be used to clean rooms and ducts.
