1 Introduction
1.1 Notes on operating instructions
These operating instructions are intended to ensure optimum installation, commissioning, operation and maintenance of the
device and must be read prior to performing any of these actions. Keep this documentation handy and accessible to all users
so that it can be refered to whenever necessary. Pass this documentation on to subsequent users of the product. All necessary
settings are described in this manual.
If any difculties should occur during commissioning or operation, please do not carry out any unauthorized manipulations.
Doing so could void your warranty.
Instead, please contact us immediately:

1.2 Explanation of icons and symbols
Danger
Indicates a hazard that could lead to personal injury.
Notice
Indicates important information which, if not observed, may result in damage to property, for example.
1.3 Intended use and foreseeable misuse
The DS01+ differential pressure transmitter is used to detect low pressures and convert them into a pressure-proportional
measuring signal. The device may only be used in the specied measuring range. Only differential pressures of non-aggressive
gases may be measured with the DS01+.
Notice
Do not use the device in explosive atmospheres or for measurement of aggressive gases.
No liability is accepted for damages resulting from non-intended use. If so, any warranty claims shall be rendered
void. Unauthorized modications, additions or alterations to the instrument are prohibited. Modications to the
device are prohibited.
1.4 Functions
Depending on the selected measuring range, the DS01+ pressure transmitter can be used to record and display positive,
negative and differential pressures.
2 Notes for your safety
Danger
In order not to endanger any person involved in the installation and commissioning of the device, such work
should only be carried out by qualied and trained personnel.
Persons using the device must also:
>be conscious of the dangers present when working next to live parts.
>take measures to protect themselves against direct contact with live parts.
>have read and understood the operating instructions.

3 Installation and start-up
3.1 Scope of delivery
The scope of delivery includes:
>1 x DS01+ pressure transducer
>1 x quick reference guide
>optional: 1 x calibration certicate
3.2 Assembly
The DS01+ pressure transmitter can be attached to the wall via the side lugs using dowels and screws.
Notice
>Mount the device on a vertical, smooth surface
>Do not mount the device in the immediate vicinity of sources of interference or heat
3.3 Start-up
3.3.1 Connection
Connect the supply voltage as well as the output wiring according to the connection diagram. For this purpose run the cables
through the cable glands attached to the housing and connect them to the screw terminals provided.
In order to guarantee the specied accuracy, the sensor should only be fully put into operation after a run-in time of one
hour. After the run-in time has elapsed, a zero point correction should be carried out to adjust the pressure transmitter to the
ambient pressure (see 4.1 Zero point correction).

4 Maintenance and service
4.1 Zero point correction
The zero position of a pressure sensor shifts over time due to external inuences and the condition of the piezoresistive
sensor element. It is therefore recommended to carry out a zero point correction before commissioning and at annual inter-
vals thereafter. To do this, connect the supply voltage to terminals 1 and 2 and then press the „S“ key. The current measured
value is now zeroed.
Danger
When working on the open device, always ensure that either the supply voltage is interrupted or suitable
protective measures have been taken against contact with live parts.
4.2 Cleaning
Cleaning of the equipment can be done with a damp cloth. Remove external soiling from the housing, the connections and
the display.
Notice
Do not use sprays, solvents, alcohol-based cleaners or abrasive cleaners to dampen the cloth.
Remove soiling of the housing, the connectors and the display.
4.3 Repair
Notice
Repairs may only be carried out by the manufacturer or appropriately authorized and qualied personnel.
If changes are made to the device independently, the warranty will expire.
5 Accessories and spare parts
The scope of accessories may vary depending on the order variation. All possible accessories are listed in Chapter 3.1 Scope
of delivery. Spare parts are to be obtained exclusively from the manufacturer. The replacement of the spare parts may only be
done by the manufacturer or an authorized technician.
6 Technical data
Technical data can be found in the corresponding data sheet, which is available at www.fsm.ag, or can be downloaded
using the QR code below.
7 Disposal
Danger
Incorrect disposal can result in hazards for the environment. Device components and packaging materials must
be disposed of in an environmentally friendly manner in accordance with the country-specic waste treatment and
disposal regulations.
