How to handle measurement data
The monitor will start registering measurement data as soon as it is switched on. This data is stored in the monitor's
internal memory. The internal memory has a 30-day capacity if both channels (P1- and P2-) are used, and a 60-day
capacity if only P1- is used. The monitor offers various options for using the obtained measurement results.
Option 1:
You do not use the supplied SD card. The display will show the percentage of the internal memory that is currently
in use. Before the internal memory is filled up completely (100%), you will need to copy your measurement data
onto the SD card (Menu; RESULTS > Copy memory). Once the internal memory is full, the monitor is no longer able
to store measurement data in this memory! As soon as you have copied the measurement data from the internal
memory to the SD card and checked whether all measurement data has been copied properly, you can delete the
internal memory without any data loss (see Menu; RESULTS > Clear memory).
Option 2:
You do use the supplied SD card. In that case, the monitor will automatically transfer the measurement data from
the internal memory to the supplied SD card every 24 hours. As such, the internal memory will never get full and all
of your measurement data is transferred to the supplied SD card in 24-hour chunks.
The display will show the indicator ‘SD OK’ when you switch it on, after which it will count down from 24 hours to 0
hours; once 0 is reached, the measurement data recorded in the last 24 hours will be transferred from the internal
memory to the SD card.
If you want to transfer data to the SD card in the meantime, you can do so manually (see Menu; RESULTS > Copy
memory). Always do so before copying measurement data to your PC, so that no measurement data is missing.
Install the Notepad++ program to be able to read out the SD card properly; see www.airtocheck.com >
‘support’.
Option 3:
You always have the option of printing out measurement data using the printer in the monitor. You can do so right
away while performing measurements as well as after the fact out of the monitor’s memory.
Web-based version:
If you use a web-based version in combination with an SMS & Data subscription or a Data subscription, your
measurement data will be submitted to the cloud immediately. You can then view the data in real time via the
Airtocheck website or app. Please make sure to check regularly whether the Internet connection is still intact.
If it is disconnected briefly (such as due to a malfunction), the monitor will supplement the missing data as
soon as the Internet connection has been re-established (firmware version 230318 or higher).
Please note! To restore missing measurement details, the monitor must not be switched off in the meantime.
Once you are sure that all measurement values have been submitted by the monitor and received by your
Airtocheck account, you are free to switch off the monitor without any data loss.
Please note! If you intend to use the monitor for longer stretches of time in a location without Internet access,
such as in a basement, make sure you store the measurement data on an SD card or print it.
Please note! You are personally responsible for creating backups and managing all of your measurement data.
Airtocheck cannot be held liable for any direct, indirect, or consequential damage resulting from your use of
the product.

Safety and preparation before use
!
Carefully read the entire manual before using the Airtocheck monitor.
Whenever the term ‘monitor’ is used in this manual, it refers specifically to the Airtocheck monitor including
all of its accessories.
This manual was created to provide a single overview regarding the installation, operation and maintenance
of the Airtocheck monitor and provide additional information on these aspects.
The Airtocheck monitor is fitted with a highly user-friendly menu and operating it is very safe, provided that
the monitor is installed, operated and maintained in exact accordance with all safety instructions in this
manual.
Safety guidelines and warnings
- These safety guidelines must be strictly observed during all stages of the monitor’s installation, operation and
maintenance.
- Failure to observe all guidelines may lead to serious damage and bodily harm and is in violation of safety
standards.
- If you have any doubts concerning safe use of the monitor, please contact your Airtocheck dealer.
- Always store this manual near the monitor. We recommend storing it in the monitor’s cover.
- The end user is responsible for safe operation of the monitor. They must check the installation and the
measurement and alarm settings, as well as the Airtocheck website and the submission and reception of
measurement data by the Airtocheck monitor.
- The end user is responsible in the event that a defect to Airtocheck equipment results in a dangerous
situation.

Risk of electric shock
!
Electric shock is the most common risk when operating electric equipment.
- Dangerous voltages may lead to bodily harm or death.
- Opening the casing is strictly forbidden.
- Always use the monitor in a horizontal position.
- Always place the monitor on a stable, level surface and prevent external influences such as liquids
and/or other objects.
- Unauthorised changes to the monitor may lead to fire and/or electric shocks and/or other hazards.
Such changes will cause all warranty claims to immediately lapse.
- You are not permitted to change out parts and/or make changes to the monitor. Such changes will
cause all warranty claims to immediately lapse.
- The monitor is shipped with a three-core earthed cable. Only ever use this accompanying cable. The
metal parts of the monitor must be connected to the earth connection to prevent electric shocks.
Always use a system with such an earth connection.
- If you have any doubts whether your system meets the requirements – including in terms of your
earth switch, which needs to be checked regularly to prevent electric shocks – please contact an
electrician.
- The use of accessories not recommended by Airtocheck is not permitted.
- First connect the cable to the monitor before plugging the power supply into the wall socket. When
disconnecting the monitor, first remove the plug from the wall socket before you disconnect the
cable from the monitor (if desired).
- To limit the risk of fire and electrocution, never expose this product to rain or moisture, and prevent
the spilling of liquids on the monitor.
- Inserting objects into any of the openings is expressly forbidden; this may result in short circuiting,
fire or electric shock.

Introduction & Block Diagram
Airtocheck offers the latest technology available for measuring negative pressure. You can opt for the web-based/SMS
version, the web-based version, or the SMS version of the Airtocheck monitor. If you choose the web-based model,
you will be able to read negative pressure values in real time via the app or website and generate measurement
reports (for more information, please go to www.airtocheck.com).
The sensors used result in very stable and exact measurements.
The supplied case offers the necessary protection for the Airtocheck monitor.
The menu is easily accessible using the symbol keys and the menu key.
If desired, you can print the results of your measurements using the built-in thermal printer.

Display clarification
Horn on/off:
This section enables you to turn the internal horn on/off.
In the event of an alarm, an indicator will appear here to
count down the set delay period before the acoustic
alarm goes off.
Measurement settings A/B/C/D/E/Off:
This section enables you to select measurement ranges
A/B/C/D or choose option E that allows you to set a range
yourself.
You can also turn off the measurement ranges fully here.
Please note! If the measurement ranges have been
turned off, this means there is no upper and lower limit
for the negative pressure, which means the system is
unable to send out alarms.
