S52
DAC Full Scale Code (Factory Read/Write)
The Analog Output D/A value used to represent full scale pressure. If in CALIBRATE state
(SS8), writes value to RAM and Sets the Analog Output to the level representing full scale
pressure; otherwise, writes value to RAM and FLASH
Range is 0 to 65535. Defaults are as follows:
0 to 5 V, 1 to 5V
0 to 10 V
0 to 20 mA, 4 to 20mA
S53
Analog Output Full Scale (Factory Read/Write)
The pressure at which the linear analog output will be at its full-scale value in Torr. If
S53=1000, at 1000 Torr, the analog output will be 10 V for a 0-10V unit or 20mA for a 4-
20mA unit. For different units, first set S22=1, then convert the desired full scale to Torr
and input the result into S53. For example, a full scale at 1000 mbar would be at S53=750.
Then set S22 to the final desired units. S53 will show in converted units. The value of S53 is
ignored for logarithmic and non-linear outputs.
S54
Comment (Read/Write)
This allows the end user to add up to 63 characters of free-format text for their own use.
S62
Cal Date (Read/Factory Write)
The date the device was calibrated at the factory. This is a text field which accepts a
maximum of 63 characters.
S63
Cal Temp (Read/Factory Write)
The temperature at which the device was calibrated at the factory. This is a text field
which accepts a maximum of 63 characters.
S64
Product Config (Read/Factory Write)
The product configuration word. Valid settings are as follows:
0x00 = 0 to 5 Volt Piezo gauge
0x02 = 0 to 10 Volt Piezo gauge
0x04 = 0 to 1 Volt Piezo gauge
0x14 = 0 to 20 mA Piezo gauge
0x1C = 4 to 20 mA Piezo gauge
When this command is executed, the system may automatically re-start.
S65
NextLine (Read/Write)
The Response Line Termination character(s) sent at the end of each line of a response.
For carriage-return (default), enter "S65=x0D".
For line feed, enter "S65=x0A".
For carriage-return linefeed, enter "S65 =x0D0A".
EAR99 Technology Subject to Restrictions Contained on the Cover Page
NOTE: do not use the greater-than sign '>' in any text field because it could affect
automated command response processing since it is used as the end-of-response
character.
