chamber (the right measuring cell flange
when viewed from the back) e.g. for

valve or A-10 Cryo or IS-20 transmitters

Cover cap for adjustable
measuring span
1. The span adjustment, situated at the ‚4 o‘clock‘ point on the instrument case, is accessible
through the case by removing the cover cap.
2. Charge the instrument to the desired nominal pressure.
3. To set the pointer to the span value, using an allen key (size 3 mm) inserted into the
funnel, turn it either clockwise (reduce the measuring range) or anticlockwise (expand the
measuring range). The gauge will then be fully adjusted to the required measuring range.
4. If the gauge is equipped with a transmitter model 89x.44 (see page 9), then this procedure
will also adjust the output signal to the new measuring range.
5. After completing the adjustment the equipment should be resealed with the cover cap.
