2. Standard
The Standard format has two digits of precision. For example, an internal vacuum value of
1234 microns (μm Hg) would be displayed as 1.2 Torr in the
Standard numeric format with
Torr units. This number format also gives a filtered number depending on the accuracy of the
gauge in the pressure range of measurement. For example, it may count by 50 Torr around
100 Torr since the accuracy in this range is +/50 Torr, which results in a ‘quieter’ gauge.
3. Scientific
The
Scientific format has two digits of precision with a base ten exponent following
conventional usage. For example, an internal vacuum value of 1234 microns (μm Hg) would
be displayed as 1.2 x 10
0
Torr. For any resolution below 2 milliTorr, the Scientific format
must be used.
C. Setpoint value
The Set Point Value is defined in terms of the current vacuum pressure units.
The Set Point indicates a pump down to configured pressure state according to the setting of the
Set Point Action. See ‘Set Point Operation’ for more detail.
D. Setpoint action
The Set Point Action is defined as one of a set of choices, including: None, Beep, Beep and
Flash, or Flash.
For details of operation, refer to the section ‘Set Point Operation’.
E. Pumpdown time
The pumpdown time configuration option defines the width of the Pumpdown Graph and
pumpdown rate window.
The pumpdown rate is the difference between the start and end of the pressure data shown in
