1.3 Directive 2014/53/EU
Hereby, Sauermann Industrie SAS declares that the radio equipment type Kistock 320 is in compliance with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address: www.sauermanngroup.com
Presentation of the device
2.1 Use
The KISTOCK class 320 dataloggers allow the measurement of several parameters:
- KT 320: internal measurement of temperature with two universal inputs for probe
- KCC 320: internal measurement of temperature, humidity, atmospheric pressure, and CO2
- KP 320 – KP 321: internal measurement of differential pressure with two measuring ranges
- KPA 320: internal measurement of temperature, hygrometry, and atmospheric pressure
- KTT 320: model with four thermocouple inputs
Communication between device and PC is carried out with a USB cable with a micro-USB female connector.
The low-energy wireless connection (possibility to deactivate this function) allows communicating with smartphones and tablets, working with Android and IOS.
2.2 Applications
The KISTOCK data loggers are ideal for different parameters surveillance (temperature, hygrometry, light, current, voltage, impulsion, relative pressure…). They ensure traceability in the food industry environment as well as validate the proper functioning of industrial installations.

Temperature in °Fahrenheit .
Relative humidity
Indicates the channel number which is measured.
The selected values to display during the configuration with the KILOG software will scroll on the screen every 3 seconds.
The display can be activated or deactivated via the KILOG software.
At extreme temperatures, the display can become hardly readable and its display speed can slow down at temperatures below 0°C. This has no incidence on the measurement accuracy.
4.2 Function of LEDs
![]() | |
| If the red “Alarm” LED has been activated, it has 3 states: – Always OFF: no setpoint alarms has been exceeded – Flashing quickly (5 seconds): a threshold is currently exceeded on one channel at least – Flashing slowly (15 seconds): at least one threshold has been exceeded during the dataset | If the green “ON” LED has been activated, it flashes every 10 seconds during the recording period. |
4.3 Function of keys
OK key: allows to start, stop the dataset, or change of scrolling group like described in the following tables.
Selection key: allows the scroll values in the scrolling group like described in the following tables.

4.3.1 Groups organization
The table below summarises the group’s organization and measured values available during a measurement dataset.

Press key to change of group.
Press the key to scroll values in the group.
4.3.2 Measurements scroll
According to the selected parameters during the configuration and according to the type of device, the measurement scroll is carried out like following: Temperature*
Hygrometry* CO2* Differential pressure* Atmospheric pressure* Parameter 1 probe 1*
Parameter 2 probe 1* Parameter 1 probe 2* Parameter 2 probe 2*
Examples:
• KT 320 KISTOCK with a thermo-hygrometric probe (channel 1) and a temperature probe (channel 2):

The measurements scroll can be carried out by pressing the “Select” button of the datalogger or waiting about 3 seconds and the display scrolls automatically.
4.4 PC communication
➢ Insert the CD-ROM in the reader and follow the installation procedure of the KILOG software.
- Plug the male USB connector of the cable to a USB connection on your computer*.
- Open the USB cap on the right side of the datalogger.
- Connect the male micro-USB connector of the cable to the female micro-USB connector of the device.

4.5 Configuration, datalogger download and data processing with the KILOG software
Please see the KILOG software user manual: “KILOG-classes-50-120-220-320”.
The date and time update automatically when a new configuration is loaded.
Wireless connection function
Kistocks of the class 320 has the wireless connection function allowing to communicate with a smartphone or a tablet (Android or iOS) via the Kilog Mobile application.
The Kistock is named “Kistock 320” in the list of available devices of the tablet or smartphone.
By default, the wireless connection is disabled on class 320 Kistocks. Please see the Kilog software applications user manuals to enable it.
Maintenance
6.1 Replace the batteries ![]()
With a 3 to 7 years battery life*, the KISTOCK guarantees long-term measurement.
To replace batteries:
- Unscrew the unlosable screw on the battery hatch on the backside of the STOCK with a cross-head screwdriver.
- The battery hatch opens. Remove the old batteries.
- Insert the new batteries and check the polarity.
- Replace the battery hatch and screw it.

Only use a trademark or high-quality battery in order to guarantee the announced autonomy.
After the battery replacement, the device must be reconfigured.
6.2 Device cleaning
Please avoid any aggressive solvent.
Please protect the device and probes from any cleaning produce containing formalin, that may be used for cleaning rooms and ducts.
6.3 Safety lock wall mount with padlock
➢ Mount the safety lock support on the required place.
- Present the KISTOCK datalogger on the support starting with the inferior part
- Clip the KISTOCK on the support by falling back the superior part
- Insert the padlock to ensure the safety lock function

➢ To remove the datalogger from the support, proceed on reverse order.
The padlock can be replaced by a fail-safe sealed
The datalogger can be placed on the screw-mount without the safety lock function
* On the basis of 1 measurement each 15 minutes at 25°C.
Calibration
A calibration certificate is available as option under paper format.
We recommend to carry out a yearly checking.

7.1 KCC 320: perform a CO2 measurement verification
To avoid potential drifts, it is recommended to perform regularly a CO2 measurement verification.
➢ Before checking the CO2 measurement, verify the atmospheric pressure values measured by the device: launch a dataset, or press the “Selection” button to scroll the measurements.
➢ If the atmospheric pressure values are not compliant, it is possible to carry out a measurement correction with the KILOG software (please see the KILOG software user manual, “Measurement correction” chapter).
➢ Once the atmospheric pressure checked, verify the CO2 measurement: launch a dataset , or press the “Selection” button to scroll the measurements.
➢ Connect a bottle of CO2 standard gas on the gas connection on the back of the KCC 320 device with the supplied Tygon tube.
➢ Generate a gas flow of 30 l/h.
➢ Wait for the measurement stabilisation (about 2 minutes).
➢ Check the CO2 values measured by the KCC 320.
➢ If these values are not compliant, it is possible to carry out a measurement correction with the KILOG software (please see the KILOG software user manual, “Measurement correction” chapter). ®
7.2 KP 320 – KP 321: perform an auto-zero
It is possible to reset the device during a recording dataset:
➢ Unplug the pressure tubes of the device.
➢ Press the “Selection” button during 5 seconds to carry out the auto-zero.
The instrument resets. The screen displays “…”
➢ Plug the pressure tubes.
The device continues the measurements and the dataset recording.
It is possible to reset the device when values are measured but not recorded:
➢ Unplug the pressure tubes of the device.
➢ Press the “Selection” button to display the measurement.
➢ Press the “Selection” button during 5 seconds to carry out the auto-zero.
The instrument resets. The screen displays “…”
➢ Plug the pressure tubes.
The device continues the measurements.
