Setting Up and Optimizing Readings

The CellScale defaults to take 16 readings per scan of each load cell. This setting can be adjusted in order to improve
scan performance.

To adjust this setting, access the master CellScale device’s terminal
menu. From the main menu, select item one.

This will bring up the "Channel Setup" menu. From here select item
four.

This will bring up the "Channel Scan List" menu. From here select
item three.

This will bring up the "Edit a Scan List entry" menu. From here
select item six.

The CellScale will prompt for the new setting

Type in the desired setting and press Enter to accept

(1) Channels/Calibration

(4) Channel Scanlist functions

(3) Edit a scanList entry

(6) # readings per dwell: 16

Adjusting the Number of Readings Per Dwell

Enter # samples to average
before channel switch (1-255):

"Enter"

For additional information on channel setup, please reference the MSI-9000 CellScale User Guide.

Scan Order

The scan list in the CellScale is the order in which the CellScale scans the channels that are monitored. If there is a
situation in which there is a channel that requires extra monitoring, it is legitimate to add the channel into the CellScale
scan list more than once. This will ensure that as the CellScale goes through the scan list, it checks the critical inputs
more than once. Reference the CellScale owner’s manual for details.
