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 PolluStat 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.
