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 qualications
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 modications 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 specied 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 specications of the built-in measuring
connections and lines as well as the specied safety factors.
- Repairs to the digital pressure gauge may only be performed by the
manufacturer. Use only original spare parts and accessories.
- Non-specied 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.

with these notices and information and handle the device with care to prevent accidents and avoid
personal injury and property damage.
DANGER
Notice indicating a dangerous situation which, if not avoided, will result in death or severe
injury.
WARNING
Notice indicating a dangerous situation which, if not avoided, could result in death or severe
injury.
CAUTION
Notice indicating a dangerous situation which, if not avoided, could result in minor to
moderate injury.
Attention
Notice indicating a dangerous situation which, if not avoided, could result in property
damage.
Note
Notice including useful tips, recommendations and information for efcient and trouble-free
operation of the digital pressure gauge.
1.3 Intended use
The DM 80-S digital pressure gauge is used for the mobile and stationary measurement of pressures.
Warning
Danger from improper use.
Any improper use and failure to observe safety and operating notices can result in serious
malfunctions as well as personal injury and property damage.
– Only use the DM 80-S digital pressure gauge as intended.
– All information in the operating instructions and safety data sheets must be strictly complied with.
1.4 Disclaimer
Failure to comply with the intended use will immediately void any warranty and guarantee claims against
the manufacturer. No liability is accepted for damage or malfunctions caused by improper use, assembly
errors or failure to observe the operating instructions.
1.5 Ambient conditions
The DM 80 UMS digital pressure gauge is only intended for use in commercial workshops.
The climatic requirements correspond to the conditions typically prevailing in Central Europe. Optimum
function is ensured between -10 °C and +50 °C. The device must be stored within a temperature range
of -20 °C to + 50 °C.
The DM 80-S digital pressure gauge must be secured against falling down.

2.2 Delivery content
– 1 Pressure gauge
–2 Sticker (1 x Bar / 1 x PSI)
– 4 Rubber protective cap, blue
If the device displays "OFL" (overow), this means that the existing pressure is too high.
The device switches off automatically after 5 minutes if there is a maximum pressure change
of 2 % of the respective end value.
3. Prior to commissioning
Check scope of delivery.
To be able to start up the DM 80-S with the desired unit (bar/PSI), the unit must be opened and adjusted
by hand.
The pressure gauge is set to bar at delivery.
If necessary, check switch position for measuring unit before use. (point 3.2)
The batteries are included in the delivery condition and are not in the instrument.
The batteries must be inserted before use.
3.1 Battery replacement
– Switch the device off and push the rubber cap towards the rear over the housing.
–Open the rear side of the device: Loosen and remove the 3 screws (hexagon socket 2.5 mm), lift the
cover off.
–Replace the batteries. Pay attention to the polarity! Batteries 2 x 1.5 V (LR6 - AA).
The power supply cables are designed to be placed over the upper anchorage of the screw.
–Restore the original state.Then the corresponding unit label (bar/PSI) must be attached to the front
side next to the digital display. These stickers are included in the delivery.
The DM 80-S is now completely ready for use.

– Set the measuring unit via the switch position
BAR: PSI:
Both switchs (1 and 2) Switch 1 to the lower position and
in the upper possition ON switch 2 in the upper possition ON
– Attach correct sticker with measuring unit to display
– Close rear side of housing (see point 3.1)
3.3 Connect the digital pressure gauge
CAUTION
Risk of injury due to leaking liquids or gases.
The discharge of media or hot liquids that are under pressure may cause injuries.
Risk of injury due to ejected parts.
Pressurised systems may burst and cause parts to be ejected.
Do not exceed the maximum pressure/load value of the smallest component of the system at
any time.
Never open pressurised ttings.
Wear personal protective equipment, such as protective goggles, gloves and safety shoes
when working on pressurised systems.
Attention
Follow the instructions and specications of the system manufacturer regarding the
tightening torques for ttings, adapters, etc.
Install the pressure gauge at the measuring point of the system. To do so, loosen or open the tting and
install the pressure gauge. Tighten ttings to the specied torque. Do not exceed the maximum torque of
the pressure gauge connection.

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.
4.2 Environmentally friendly disposal
