PRTPC
Purpose
Set or read the mounting post PRT temperature sensor calibration data.
Syntax
“PRTPC=Sn, slope, zero, report number, cal date”
“PRTPC”
Default
1, 0.3896, 100.00, 1, 19880101
Argument
Sn:
The serial number from 0 to 9999
slope: The PRT slope (Ohms/0
°
C)
zero: The PRT resistance at 0
°
C
cert number:
The calibration report number
cal date
The calibration date (yyyymmdd)
Remarks
The mounting post PRT data can be read or set using this command. Care must be
taken to ensure that you do not accidentally overwrite this date.
Example Typical
command:
Typical reply:
“PRTPC”
“103, 0.3896 ohms/dC, 99.999500 ohms, 1001, 19990115
Error

PR
Purpose
Read the current calculated pressure value and
Ready/Not Ready
status.
Syntax “PR”
Default N/A
Argument N/A
Remarks
The current pressure resulting from the mass loaded is calculated every 2 seconds. It is
displayed in the current pressure units. The data string also contains ready information.
The string is in the format “ssx dddddddd uuuum”.
“ss”: The first two characters indicate the ready status. This is determined by the
piston position, rotation speed, AMH automated mass handler status, and the
pressure generation status:
“R ”
for
Ready
,
“NR”
for
Not Ready
.
“x”:
This 3
rd
character indicates any ongoing activity by the PG7000 to reach a
Ready
condition. Any character except a “
” (whitespace) will keep the PG
ready status
Not Ready
(“NR”):
“
”
no activity.
“A”
the auto rotate feature is accelerating mass rotation.
“D”
the auto rotate feature is decelerating mass rotation before a mass load
occurs.
“R”
the piston is being raised by a pressure controller before a mass load
occurs.
“L”
AMH automated mass handler is busy loading the required mass load.
“W” AMH has completed a mass load and is waiting for a “RESUME”
command to continue operations.
“E”
an AMH error has occurred. You can use the “AMHERR” command to
get further AMH error information.
“V”
the PG is in absolute by vacuum mode and waiting to reach the required
vacuum limit before continuing. Current residual pressure exceeds the
vacuum limit.
“dddddddd”: This 8 digit numeric field indicates the current calculated pressure in the
current pressure units. It has 3 leading spaces before it.
“uuuu”: This 4 character field indicates the current pressure unit.(see “UNIT” )
“m”:
This character indicates the measurement mode. (see “MMODE” ).
Example Typical
command:
Typical reply:
“PR”
“NR 7.003647 kPa g” (not ready)
“R 7.003647 kPa g” (ready)
“NRL 7.003647 kPa g” (not ready, busy loading mass)
Error None
