(‘C’ + 5 numbers).
(e.g. 05708 = 5.7 X 10-8 atm-cc/sec)
(e.g. 10010 = 10.0 X 10-10 atm-cc/sec)
In software rev 7.2 and later, the mantissa length is set via Revision
Switch 8. Format is either 6 or 7 characters. UP = mantissa single
decimal XX.X, DOWN – mantissa two decimal XX.XX
‘D’ - Followed by 1 to 6 numbers.
Fore-line Pressure measured in Millitorr (from 0 to 760000 millitorr).
(e.g. 100 = 100 millitorr)
(e.g. 760000 = 760000 millitorr)
In software revisions 3.8 and later, this field is fixed at 7 characters.
(‘D’ + 6 numbers).
(e.g. 0f00100 = 100 millitorr) (e.g. 760000 = 760000 millitorr)
‘E’ - Followed by 1 to 6 numbers.
Test-port Pressure measured in Millitorr (from 0 to 760000 Millitorr).
(e.g. 200 = 200 millitorr)
(e.g. 50000 = 50000 millitorr)
In software revisions 3.8 and later, this field is fixed at 7 characters.
(‘E’ + 6 numbers).
(e.g. 000100 = 100 millitorr)
(e.g. 760000 = 760000 millitorr)
‘F’ - Followed by 6 characters.
High Vacuum Pressure measured in Torr (from 7.5 x 10-4 to 2.6 x 10-5).
(e.g. 2.6x-5 = 2.6 x 10-5 Torr)
(e.g. 1.5x-4 = 1.5 x 10-4 Torr)
In software revisions 3.8 and later, this field is fixed at 4 characters.
(‘F’ + 3 numbers).
(e.g. 105 = 1.0 X 10-5 Torr)
(e.g. 384 = 3.8 X 10-4 Torr)
‘G’ - Followed by 2 numbers.
Filament Current measured in amperes. (e.g. 23 = 2.3 Amps.)
In software revisions 3.8 and later, this field is fixed at 4 characters.
(‘G’ + 3 numbers).
(e.g. 023 = 2.3 Amps.)
