If DISPLAY LOW SAMPLE LOAD is enabled, screens similar to the one below will be
displayed during sample loading. In this example, the target sample size is 5g and the
sample window is 0.3g. The initial LOAD SAMPLE screen (below left) shows a value of
4.4g, which is (Sample Size – 2 x Sample Window). When the loaded weight reaches
4.4g, the display switches to the normal LOAD SAMPLE window (below right). This
feature reduces the chance of overshooting the intended sample size when loading the
pan, as the sample weight is continuously visible.

NITROGEN CONTROL MODULE
This menu enables the Nitrogen Control
module (See section

The following options are available:
•
ENABLE N2 DURING TESTS

it be connected with good pressure.
When appropriate, error messages
are displayed during a test and when
returning to the main screen at the
end of a test.
•
NITROGEN VALVE manually controls the operation of the valve if ENABLE N2
DURING TESTS is set to “Yes”, and may be used for diagnostic purposes. Starting
the next test will reset the valve to its proper state.
•
NITROGEN PRESSURE displays the status of the nitrogen pressure from the
regulator.
•
FIRMWARE VERSION displays the firmware version of the module.
These options are not applicable if nitrogen purge is being used without the Nitrogen
Control module.
