WARNING
WARNING: electric arcing
Helium may cause electric arcing with detrimental
effects on the electronics of the product.
Before performing any tightness tests put the pro-
duct out of operation and remove the electronics
unit.
The gauge may be mounted in any orientation. To keep
condensates and particles from getting into the measur-
ing chamber preferably choose a horizontal to upright
position and possibly use a seal with a centering ring
and filter.
If adjustment should be possible after the gauge has
been installed, be sure to install it so that potentiometers
<HV> and <ATM> can be accessed with a screwdriver
(
