Note
The local gravity (gl) value may or may not be used by PG9000 in its
calculations of defined pressure. Whether gl or another value, such as
normal gravity, is used is determined by the active SETUP file selection
(see Section 3.11), not by what is entered by pressing [SPECIAL] and
selecting <6gl>.
3.12.7 <7cal>

PURPOSE
To view or edit the calibration coefficients for PG9000’s internal sensors and measurement
systems including:
Barometric pressure Ambient relative humidity
Ambient temperature Piston-cylinder module temperature
Vacuum Piston position
Piston rotation rate
Note
In normal operation, the measurements made by PG9000s internal sensors
can be viewed in the SYSTEM and AMBIENT run screens by pressing
[SYSTEM] or [AMBIENT] (see Sections 3.10.5 and 3.10.6).

PRINCIPLE/OPERATION
PG9000 internal sensor calibration functions are considered part of PG9000 maintenance
and are covered in the maintenance section of this manual (see Section 5).
3.12.8 <8AMH>

PURPOSE
Control the optional AMH system and to view its status (see Section 3.7).

PRINCIPLE
An optional automated mass handling system is available for PG9000 Platforms. AMH-100-
VAC operates in either atmospheric reference (gauge or absolute by ATM) or vacuum
reference (absolute by vac or differential) modes (see Section 3.10.4).
Operation of the AMH is integrated into PG9000 Platform operation so that mass handling
occurs automatically when required. The PG9000 commands the operation of the AMH.
[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 must already be initialized by
selecting an AMH type mass set (see Section 3.12.1.10). 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 3.12.8.2).
Select <2control> to control AMH directly:
<1up/down> to move the AMH mass actuator up or down (see Section 3.12.8.1).
<2discreet> to specify the masses to be loaded and unloaded (see Section 3.12.8.2).
<3loadall> to load all the AMH masses onto the piston (see Section 3.12.8.3).
<4unloadall> to unload all the AMH masses from the piston (see Section 3.12.8.4).
