1. Safety
1.1 Safety notes and regulations
To ensure safe and reliable work with the digital pressure gauge and to protect the user from
injuries, the following points are to be observed:
- Read the operating instructions carefully.
- The digital pressure gauge may only be operated and installed in systems by
trained specialists who possess the necessary expertise and qualications
to perform these tasks, and who are familiar with the applicable standards,
regulations and requirements of the eld of application.
- The operating instructions are an integral part of the digital pressure gauge.
Store the operating instructions in a safe location so that you can quickly nd the
desired information if necessary.
- The legal provisions and regulations as well as those of the system/vehicle
manufacturer are generally to be observed.
- Prior to commissioning, perform a check to ensure that the digital pressure gauge
is in faultless condition. Do NOT operate the digital pressure gauge if damaged.
- No technical modications to the digital pressure gauge may be made.
- Protection class according to DIN 60529: The ambient conditions at the place
of use must not exceed the requirements for the specied protection class (see
Technical data).
- Do not subject the digital pressure gauge to any extreme temperatures, direct
sunlight, extreme humidity or wet.
- Observe the measurement range limits and temperature ranges.
- Do not exceed the maxim measurement range limits and temperature ranges of
the digital pressure gauge at any time.
- The maximum pressure/load range of the system or component with the lowest
value is the decisive maximum value for the overall pressure/load range.
- Do not exceed the maximum pressure/load value of the smallest component of
the system at any time.
- Always observe the nominal pressure specications of the built-in measuring
connections and lines as well as the specied safety factors.
- Repairs to the digital pressure gauge may only be performed by the manufac-
turer.
- Use only original spare parts and accessories.
- Non-specied use of the product or failure to observe the safety and operating
notes may lead to severe malfunctions as well as personal injury and property
damage.
- The discharge of media or hot liquids that are under pressure may cause injuries.
- Pressurised systems may burst and cause parts to be ejected.
- Wear personal protective equipment, such as protective goggles, gloves, safety
shoes, etc. when working on pressurised systems and components.

5. Handling instructions
5.1 Care and storage
To enable e󰀨ective working, we designed the digital pressure gauge to be low maintenance. Never-
theless, you should still observe a few notes. This helps to ensure trouble-free operation and to preserve
the value of the technology.
Note:
Aggressive cleaning agents or solvents may damage the digital pressure gauge or individual
components.
Do not use aggressive or abrasive cleaning agents, solvents or similar chemicals for cleaning.
–Keep dust and dirt away from the digital pressure gauge.
–Clean the digital pressure gauge with a soft, slightly moistened cloth.
–Pay attention to the self-discharging of the battery. (We recommend charging the battery every 8 weeks).
–Battery warranty 6 months / device warranty 12 months.
–Store your product in a dry, dust-protected environment. Avoid places with higher temperatures and
moisture or places which can become wet, also for maintenance.
–Keep the original packaging to avoid damage during transportation.
5.2 Environmentally friendly disposal
Recycling according to WEEE (EU Directive 2002/96 EC)
You can optionally return the digital pressure gauge to us for disposal.
This digital pressure gauge or its components must not be disposed of as normal waste.
If you prefer not to return the digital pressure gauge to us for disposal, you are required to bring the
device to a specialised centre for the separate collection and disposal of hazardous and special waste.
The digital pressure gauge contains an electronic circuit board and a battery. These parts must be
removed before the device is scrapped.
