4 Operation

Put the gauge into operation. If you are using an INFICON con-

troller, define the measurement range (→  [1, 2, 3]).

A warm-up time of at least ½ hour should be allowed; for precise

pressure measurements a warm-up time of at least 2 hours is

required.

If the gauge is used for fast downstream pressure con-

trol we recommend setting its signal filter to "fast".

The filter can be set via the RS232C interface or the

diagnostic port (→  [4]).
