>>Retain Tare
This controls whether the most recent tare value is retained through power down of
the unit and used again immediately on power up. Switching “On” this setting will
retain the tare on all channels.
>>EOT Char
The End Of Transmission Character is a non-visible character (hexadecimal 0x04)
that is sent at the end of each response by the unit to a Serial command. The
character is sent after the last carriage-return line-feed is returned by the unit with just
one exception: when the user is viewing channel values with the Serial command
@123V(item)(unit)(repeat) … and sets the value of repeat to 2 (streaming output), the
character is sent immediately prior to the streaming output that the unit will send. The
user can turn this option on or off.
>>TEDS
OPT
Enable

TEDS33 enabled sensor will automatically load its calibration information into the
M9840 after attachment.
>>Auto Tare
The Auto Tare can be turned on or off in this menu. When on, it will perform an
automatic tare when an AutoID or TEDS enabled sensor is attached.
>>Serial Cmd Select
The source of serial commands can be toggled in this menu. The user can select
RS232 or USB.
>Display Options
This menu contains options that effect how cell data is treated for displaying purposes on
both touch screen and communication terminal window.
>>Filter Select
There are two types of filters available on the Model 9840: Type I, and Type II. Type I
filters are good for removing most kinds of noise but may leave some jitter on the end
digits. Type II filters are more advanced and are optimized for the typical industrial
environment. Both filter types allow you to select from 4 levels of filtering with Level 1
being the least filtering and Level 4 being the most filtering.
The settling time for each of the 4 levels of filtering is shown in the table below
