Pulse outputs for volume:
The pulse value for volume is always determined by the second-to-last place of the volume display.
Example:
Display: 0,000 m³ -> pulse value: 10 l/pulse (0,01 m³/pulse)

2 Retrofitting with an Additional Communication Interface
During installation of the retrofitting module observe the ESD requirements according to EN 61340-5-1.
This means that on location an antistatic wrist strap with an integrated 1 MΩ resistor has to be used which must be
connected to a proper spot: This is either a grounded pipe or – only with an appropriate adapter! – a Schuko plug
grounding socket. The antistatic wrist strap must be worn tightly on the skin of the wrist.
2.1 Retrofitting S3 with an additional communication interface (optional)
We also offer a retrofittable meter to which communication interfaces can be added later.
To retrofit such a meter with an additional communication interface the calculator´s adhesive seal has to be
destroyed and the device´s calculator to be opened. Use a screwdriver with a wide tip (4 - 5 mm) and carefully
press in the two round predetermined breaking points above the cable feedthroughs (see picture 1).
Then insert the screwdriver into one of the two openings at an angle of approx. 45° and carefully lift the handle up
to approx. 90° (see picture 2). The upper housing piece of the calculator is then no longer latched on this side.
Repeat this with the other opening. Now the upper housing piece can be taken off.
