ADC
This menu is used to:
• display material weight of each vessel and
the equivalent A/D counts
• enable or disable monitoring for a channel
• adjust the excitation, effective resolution,
and gain
• set (or reset) default parameters for a
specific channel
• set up and enable filtering and tracking
parameters that reduce the effects of
‘noise’ and drift
Descriptions of each of the submenus follow.
Disp
This function allows you to display the current
material weight, equivalent A/D counts, and
stability. Both ‘corrected’ and ‘raw’ A/D
counts are displayed. ‘Corrected’ counts are
the counts after all system corrections, such
as averaging, linearization, filtering, and
tracking, are applied. ‘Raw’ counts are the
counts before any corrections are applied.
The first page of the display looks like this:
• 04 is the factory-set channel ID
• 1043962 Cts is the current “corrected” A/D
counts
• CB is the hexadecimal serial address for
the current channel
• 25733 lbs is the current material weight
The remaining pages are displayed by
pressing the F3 Key. The second page of the
display looks like this:
• 04 is the factory-set channel ID
• 1043962 Cts is the current ‘corrected’
A/D counts
• CB is the hexadecimal serial address for
the current channel
• 21Bit is the effective resolution
• d=5 is the change in counts, which is a
measure of channel stability. Kistler-Morse
may be interested in this number if, while
vesel monitoring, the display jumps or
drifts excessively. The value for d is zeroed
by pressing the Enter Key while viewing
this display. The maximum value is 255.
When d exceeds 255, the number is
replaced by *** on the display.
The third page of the display looks like this:
• 04 is the factory-set channel ID
• 1043962 Cts is the current ‘corrected’
A/D counts
• CB is the hexadecimal serial address for
the current channel
• 1043990 Raw is the current ‘raw’ A/D
counts
Pressing the Up and Down Arrow Keys
cycles the display through the other
channels.
Enab
This function is used to enable or disable the
channel. This function differs from the Hide
Menu in the Display Menu (see Chapter 4,
Display) in that disabling a channel using
Enab actually causes the Weigh II to stop
monitoring the channel. The display shows:
An asterisk indicates the current selection for
the channel. Pressing the F1 Key enables
the channel. Pressing the F3 Key turns the
channel off. If you have setpoint or current
output set up for the channel that you are
disabling, the Weigh II will ask whether to
Release I/O. Releasing I/O will free up those
channels currently used for setpoint and
current output for this vessel. If you want to
retain the previously entered setpoint and
currrent output information, do not
Release I/O.
Pressing the Up and Down Arrow Keys
cycles the display through the other
channels.
Note
There are a total of 8 channels in
Enab. For a single-point system,
channels 2 through 8 are math chan-
nels. For a multi-point system, chan-
nels 5 through 8 are math channels.
Refer to Chapter 8, Math Channels, for
detailed information.
