Calibration
Confirm that these safety devices are properly installed before installing the
product. In addition, check that:
a.
The proper gas cylinders are installed,
b.
Gas cylinder valve positions are correct on manual systems, and
c.
The automation is correct on automated gas delivery systems.
Vacuum gauges with compression fittings may be forcefully ejected if the
vacuum system is pressurized.
Proper Grounding:
All components of a vacuum system used with this or
any similar high voltage product must be maintained
at Earth ground for safe operation. The power cord
of this product shall be connected only to a properly
grounded outlet. Be aware, however, that grounding
this product does not guarantee that other
components of the vacuum system are maintained at
Earth ground.
Complying with the usual warning to connect the
power cable only to a properly grounded outlet is
necessary but not sufficient for safe operation of a
vacuum system with this or any similar high voltage
producing product.
Verify that the vacuum port to which the
Mini−Convectron Gauge is mounted is electrically
grounded. It is essential for personnel safety as well
as proper operation that the envelope of the gauge be
connected to a facility ground. Use a ground lug on a
flange bolt if necessary.
Using the N
2
calibration to pressurize a vacuum
system above about 1 Torr with certain other gases
can cause dangerously high pressures which may
cause explosion of the system. See Chapter 4 before
using with other gases.
Warning − If used improperly, Mini−Convectron
Gauges can supply misleading pressure indications
that can result in dangerous overpressure conditions
within the system.
