MRES(=)
Purpose Read or set the PG9000 mass loading resolution.
Syntax “MRES=massResolution”
“MRES”
Default “MRES=0.01g
Argument MassResolution: The mass loading resolution in grams.
Remarks You must set the resolution that PG9000 uses to convert user provided pressure
requests into mass loads. PG9000 will calculate the required mass load to the precision
defined by the mass loading resolution. The maximum resolution is 0.001 gram, and the
minimum is 100 g. The mass resolution is automatically set to 100 g whenever an AMH
mass set is made active or AMH is initialized.
Example Typical command:
Typical reply: “MRES=.01”
“MRES=0.010g”
Error See Section 4.3.3 Error Messages
ERR #1 The resolution given is greater that 100g of less than 0.001 g
See Also 3.10.10
MROT(=)
Purpose Read or set the manual motorized piston rotation status.
Syntax “MROT=rotationStatus”
“MROT”
Default “MROT=0”
Argument Rotation Status: “ 1” Accelerates the piston rotation.
“-1” Decelerates (brakes) the piston rotation.
“ 0” Aborts current acceleration or deceleration
Remarks The rotation of the PG9000 piston (with bell installed) may be controlled manually
instead of using the auto rotate function (see the “AROT” command). The PG9000 will
only rotate the piston if the bell is installed and the piston position is not near or against
the top stop or bottom stop of the piston travel. This command is not typically used
when the auto-rotate feature is enabled.
Example Typical command:
Typical reply: “MROT=1”
“MROT=1”
Error See Section 4.3.3 Error Messages
ERR #1 The argument given is not “-1”, “0” or a “1”
See Also 3.10.13, 3.10.8, “AROT”
MR
Purpose Read the current mass load variables.
Syntax “MR”
Default N/A
Argument N/A
Remarks The actual true mass value, main mass nominal value, and trim mass values of the
active mass load are retrieved with this command. The data is provided in the following
comma delimited format:
aa.aaaaaaa kg, mm.m kg, t.ttt g
Where:
aa.aaaaaaa kg: The actual total true mass value.
mm.m kg: The total of the main masses nominal values (mass > 0.1 kg).
t.tttg: The trim mass loaded.
These values are the result of a user provided pressure request or mass request. Since
the actual total true mass value is a result of the true mass values, its resolution is not
controlled by the “MRES” command.
Example Typical command:
Typical reply: “MR”
“20.687002 kg, 20.6 Kg, 77.000 g”
Error None
