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

manufacturer. 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.

identication.

The notices begin with signal words that indicate the extent of the danger. You must absolutely comply

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 efcient 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" (overow), 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 specications 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 specied torque. Do not exceed the maximum torque of

the pressure gauge connection.

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.

4.2 Environmentally friendly disposal
