For adjustable devices the adjustment re-

quires to apply the lower limit pressure re-

spectively the upper limit pressure to the de-

vice. Bring the enclosed or another magnet

just accordingly. After approx. 2 seconds a

light signal in the scale acknowledges the

adjustment of the measurement range

begin and/or the adjusted range. The ad-

justment is possible within a tolerance of ap-

prox. ± 5 % F.S. Any settings that differ from

this will not be accepted.

The diaphragm must not be touched. Do not place the device on its diaphragm. Even small

scratches or deformations may negatively influence the zero point or other characteristics

of the device.

Pressure transmitter and diaphragm seal are a closed system that must not be separated.
