The local gravity (gl) value may or may not be used by PG7000 in its calculations of defined
pressure. Whether gl or another value, such as normal gravity, is used is determined by the
current SETUP file (see Section 3.10), not by what is entered by pressing [SPECIAL] and
selecting <6gl>.
3.11.7
<7CAL>
PURPOSE
To view the output of and adjust or calibrate PG7000’s internal sensors and measurement
systems including:
Barometric pressure
Ambient relative humidity
Ambient temperature
Piston-cylinder module temperature
Vacuum (PG7601 only)
Piston position
Piston rotation rate
In normal operation, the measurements made by PG7000s internal sensors can be viewed
in the SYSTEM and AMBIENT run screens by pressing [SYSTEM] or [AMBIENT]
(see Sections 3.9.5 and 3.9.6).
PRINCIPLE/OPERATION
PG7000 internal sensor adjustment functions are considered part of PG7000 maintenance
and are covered in the maintenance section of this manual (see Section 5).
3.11.8
<8AMH>
PURPOSE
Control optional AMH automated mass handling system directly and view its status (see the
AMH-38/AMH-100 Operation and Maintenance Manual for information).
PRINCIPLE
An optional automated mass handling system is available for PG7000 Platforms. AMH-38 is
used with PG7601 and AMH-100 is used with other models.
Operation of the AMH is integrated into PG7000 Platform operation so that mass handling
occurs automatically when necessary.
[SPECIAL]
,
<8AMH>
accesses functions to view the
current mass loading status, load all masses, unloaded all masses and load specific masses.
OPERATION
To access the AMH status and control functions, an AMH automated mass handler must
already be initialized by selecting an AMH type mass set (see Section 3.11.1.10). To access
the AMH status and control functions, press
[SPECIAL]
,
<8AMH>
.
Select
<1status>
for a display of the current loaded/not loaded status of AMH masses (the
indication is the same as the discreet control function screen in Section 3.11.8.2).
