DANGER
DANGER: overpressure in the vacuum system >1 bar
Injury caused by released parts and harm caused by escaping process
gases can result if clamps are opened while the vacuum system is
pressurized.
Do not open any clamps while the vacuum system is pressurized. Use
the type of clamps which are suited to overpressure.
DANGER
The gauge must be electrically connected to the grounded vacuum
chamber. This connection must conform to the requirements of a pro-
tective connection according to EN 61010:
• CF connections fulfill this requirement
• For gauges with a KF vacuum connection, use a conductive me-
tallic clamping ring.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vacuum component.
When handling vacuum components, take appropriate measures to
ensure cleanliness and prevent damages.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare hands increases the
desorption rate.
Always wear clean, lint-free gloves and use clean tools when working
in this area.
The gauge may be mounted in any orientation. To keep condensates
and particles from getting into the measuring chamber, preferably
choose a horizontal to upright position. See dimensional drawing for
space requirements (
→ 12).
The gauge is supplied with a built-in grid. For potentially contaminating
applications and to protect the electrodes against light and fast charged
particles, installation (
→ 15) of the optional baffle is recommended
( → 45).
When installing the gauge, make sure that the area around the con-
nector is accessible for the tools required for adjustment while the gauge
is mounted (
→ 38, 41).
When installing the gauge, allow for installing/deinstalling the connectors
and accommodation of cable loops.
If you are using a gauge with display, make sure easy reading of the
display is possible.
Vacuum connection free of grease.
