1Safety precautions
1.1 Appropriate use
The AD 1000 absolute pressure transmitter / BA 1000 barometer is designed for displaying
atmospheric pressure and absolute pressure in such areas as weather stations and airports.
Always observe the operating requirements—particularly the permissible supply voltage—
indicated on the rating plate and in the “Technical data” section of this manual.
The instrument may only be handled as indicated in this manual. Modifications to the
instrument are prohibited. The manufacturer is not liable for damages caused by improper use
or failure to follow these instructions. Violations of this type render all warranty claims null and
void.
1.2 Shipping, assembly, electrical connections and start-up
Do not close the pressure input ports when shipping, as changes in barometric pressure could
damage instruments with low measuring ranges.
Only technical personnel who are appropriately trained and authorized by the operator of the
facility may assemble the instrument and set up its electrical connections.
The instrument may only be operated by appropriately trained individuals who have been
authorized by the operator of the facility.
Pressurized air or breath is not to be used for performance tests, as this could damage
instruments with low measurement ranges.
Measurement errors may occur if the instrument is not kept protected from sunlight.
Specific safety precautions are given in individual sections of this manual.
1.3 Troubleshooting, maintenance, repairs, disposal
The individual responsible for the electrical connections must be notified immediately if the
instrument is damaged or if errors occur.
This individual must take the instrument out of service until the error has been corrected and
ensure that it cannot be used unintentionally.
Always unplug the power cord before opening the instrument!
This instrument requires no maintenance.
Only the manufacturer may perform repairs that require the housing to be opened.
The electronic components of the instrument contain materials that can be reused.
For this reason the instrument must be recycled in accordance with the environmental
guidelines of the jurisdiction in question once it has been taken permanently out of service.

2 Instrument description
The AD 1000 absolute pressure transmitter / BA 1000 barometer is designed for displaying
atmospheric pressure and absolute pressure in such areas as weather stations and airports.
At the heart of the unit is an evacuated CuBe chamber that contracts in proportion to
barometric pressure. An inductive displacement transducer measures the movement of the
chamber without making contact. The pressure port is led through in the AD 1000.
3 Start-up
3.1 Features
Although the AD 1000 absolute pressure transmitter / BA 1000 barometer is highly robust, it is
nevertheless a precision instrument and should be handled with care. Avoid mounting the AD
1000 / BA 1000 in the direct vicinity of any sources of heat or radiation. Ideally, the instrument
should be mounted vertically (pressure and vacuum ports should be pointing down) and on a
wall not subject to vibration.
3.2 Electrical instrument connections:
Observe the required supply voltage (see rating plate)
The pressure transmitter is protected against reverse polarity of the supply voltage.
The signal output is protected against short circuits for a short period.
