AMHERR
Purpose To read the last known error message from an active AMH.
Syntax “AMHERR”
Remarks If an optional AMH is being used, it can generate its own error message during
operation. This usually occurs if the AMH is not properly setup, for example the drive air
pressure is inadequate, or it has a mechanical failure. If the AMH fails to operate as
expected, the 3rd character of the “PR” command reply is an “E”. If this occurs, the
“AMHERR” command can be used to get the specific AMH error message, refer to
Section 3.7.2.8. It is not recommended to routinely poll the PG with the AMHERR
command as the response may contain a previous error that is recoverable by the PG.
It is instead recommended to use the “PR” command to detect an AMH error first.
The AMH error message is cleared by the next successful AMH operation or by sending
the “*CLS” command. If there is no error, “OK” is returned.
Example Typical command:
Typical reply:
Typical reply: “AMHERR”
“ERR#122” (Section 3.7.2.8)
“OK”
(no AMH errors or AHM not active)
See Also Section 3.7.2.8; ”PR”
AMHLOAD(=)
Purpose Load or unload all the AMH’s masses (used with optional AMH automated mass
handling system).
Syntax “AMHLOAD=action”
Default N/A
Argument action: ‘0’ Unloads masses from off the piston-cylinder
‘1’ Loads all masses onto the piston-cylinder
Remarks The optional AMH system can load and unload masses on the PG9000 piston-cylinder
automatically. The masses can all be loaded onto the piston or unloaded and held in
the mass handler by a single command. Setting ‘1’ causes the AMH to operate to load
all the masses. Setting ‘0’ causes the AMH to operate to unload all the masses. This
command can only be executed when the an AMH mass set is selected and the AMH is
idle. The operation can take several seconds to complete before the PG replies to this
command. The PG uses the resulting mass load for its current pressure target. The PR
command should be used to check for the presence of AMH errors after the load
change. If PR returns with an “E”, then issue AMHERR for a specific list of AMH errors.
Example Typical command:
Typical reply: “AMHLOAD=1”
“AMHLOAD=1”
Error See Section 4.3.3 above Error Messages
ERR #1
Invalid or missing argument
ERR# 13 AMH is not enabled
ERR# 37 AMH load / unload operation error
ERR# 40 AMH is not idle
See Also 3.12.8, 3.12.8.3, 3.12.8.4, 3.7
See Also 2.4.10, 3.7.1, “MASS=”, “MASS n ”
Error See Section 4.3.3 Error Messages
ERR #1
Invalid mass load or AMH not active.
AMHMS(=)
Purpose Read or set the discrete AMH mass load.
Syntax “AMHMS= main, binary ”
“AMHMS”
Argument main :
bin :
The number of main masses to load
The binary mass load. This is a sum of the binary masses to load:
1: 0.1 kg mass
2: 0.2 kg mass
4: 0.4 kg mass
8: 0.8 kg mass
16: 1.6 kg mass
32: 3.2 kg mass
64: 6.4 kg mass
Remarks An AMH mass set must be active and an AMH must already be initialized to use this
command. The PG9000 will reflect the requested mass load in the displayed pressure
measurements. The RESUME command is not required to initiate the auto float
sequence when automatic pressure generation is enabled.
Example Typical command:
Typical reply: “AMH=3,19” (3 main masses plus 1.9 kg binary mass load,
where 19 = 1+2+16)
“3, 19”
