Select <7vac> to specify the reference vacuum variable source for the value used for the
pressure under the bell jar when calculating the absolute pressure defined in absolute by
vacuum mode. Pressing <7vac> offers the reference vacuum variable source choices:
<1COM2>:
Use real time readings from the device connected by RS232 to PG9000’s COM2
port.
<1COM2> is the selection for the standard PG9000 reference vacuum sensor
included with the optional vacuum reference hardware. If a different external vacuum
gauge is used in place of the default, it must be properly set up to communicate with
PG9000 (see Section 3.12.5.5).
<2normal>:
Use a fixed value of 0 Pa.
<3user>:
Use a fixed user entered value. If <3user> is selected, the user value must be
entered, in Pascal (Pa).

OPERATION
To access the SPECIAL menu, press [SPECIAL] from
the main run screen. This display is:

7cal 8AMH 9reset
Note
Some screens, such as the SPECIAL menu, go beyond the two lines
provided by the display. This is indicated by a flashing arrow in the
second line of the display. Press the [
←
] and [
→
] keys to move the cursor
to access the lines that are NOT visible or directly enter the number of the
hidden menu choice if you know it.
Special menu choices include:
<1PC/MS> : Edit and view stored piston-cylinder module and mass set metrological
information. Select mass set to be used (see Section 3.12.1).
<2presU> : Customize the pressure unit of measure choices available under [UNIT]
(see Section 3.12.2).
<3head> : Change the height unit of measure and the fluid used in DUT head corrections;
adjust the barometer head height; turn the automated piston position head
correction ON and OFF (see Section 3.12.3).
<4prefs> : To access a menu of internal PG9000 operational preferences and functions
including screen saver, sounds, time/date, instrument ID and user level
protection (see Section 3.12.4).
<5remote> : Set up/modify PG9000 RS232 (COM1, COM2, COM3, COM4) and IEEE-488
interfaces. Test RS232 ports. Set up external barometer or vacuum gauge
communications (see Section 3.12.5).
<6gl> : Set the value of local gravity used by PG9000 in reference pressure
calculations when
gl is specified as the gravity value in the active SETTINGS
file (see Section 3.12.6).
<7cal> : View the output and/or adjust PG9000 internal sensors and measurement
systems (see Section 3.12.7).
<8AMH> : View the status and directly control an AMH (see Section 3.12.8).
<9reset> : Access and execute various reset options (see Section 3.12.9).
