4. Place material to be weighed into or on the tared item on the scale …
Net weight of material is displayed.
5. Repeatedly press SELECT to view the gross, tare, and net values.
6. If repeated weighments use the same tared item, you do not need to establish
a new tare value as described in step 2and 3.
Using Scroll Tare
If enabled you can scroll in a tare value using the following procedure.
1. Press the SELECT key repeatedly until the tare value is displayed. This is
indicated by the TARE annunciator.
2. Press the TARE key and scroll in the tare value using the Numeric entry

3.1.4 Using setpoints
Setpoints are values (weight) at which outputs are triggered automatically. Outputs can
control relays connected to valves, lights, other machinery, etc. See the Supervisor
menu on page 39 for information on how to edit or enter setpoint values.
See the note below for an overview of how setpoints function.
3.1.5 Printing
To print the current weight information, press PRINT. The configured print format will be
output through the configured port to the connected peripheral device. The indicator
can be configured to only allow one print for each weighing sequence. If PRINT is
pressed when so configured, the message cAnt will appear.
Refer to Default print formats on page 35.
By default all setpoints are disabled. If activated, they behave differently in the
different applications. See the table below:

stable, the display will show the correct number of parts on the scale
and COUNT is lit.

T401S Indicator User Instructions 17
3.3 Counting application
b If the sample size was not large enough or if the weight was unstable,
Abort is briefly displayed and the display returns to gross weighing
mode. Repeat steps 3through 5using a larger sample size.
5. Place the parts on the scale to be counted. To accumulate the count and
number of transactions, press PRINT while in count mode.
6. If enabled, press and hold PRINT for three seconds to print and/or clear the
active count total. These functions are enabled or disabled in a password

3.4 Checkweighing application
This section applies if your indicator has the Checkweighing application enabled.
3.4.1 SELECT key default function
In the Checkweighing application you can view the gross, net and tare display values
by repeatedly pressing SELECT.
3.4.2 Special key functions
The following keys have an extra function in this application:
F1 Press F1 to set the target weight or upper and lower limits, as described
below.
3.4.3 Checkweigh operation
Checkweighing allows a quick, visual check of the acceptability or unacceptability of an
item’s weight. Figure 3.1 shows the checkweighing bargraph at the top of the display.
Figure 3.1 Checkweighing bargraph
There are two ways to set a target weight:
lWeigh the target object - If you use this method the acceptable weight will
be the actual weight of the target sample ± a predefined range (default is ±1
division).
lKey in upper and lower weight limits - If you use this method the
acceptable weight is any weight which falls between the upper and lower
limits.
Each of these is explained below.
Under OverAccept
The checkweighing annunciators are based off of net weight so if a tare is active only
the net weight is considered for checkweighing. If there is no tare, gross weight is
used as the basis for the annunciators.

T401S Indicator User Instructions 19
3.4 Checkweighing application
3.4.4 Weighing a target object
With the indicator in checkweighing mode, follow these steps to set a target by
weighing an object.
1. Press ZERO to zero the scale, if necessary.
2. Enter a tare if necessary. Refer to Net weighing on page 13 for instructions.
3. Place an object of the desired weight on the scale and press F1 …
The weight is displayed and the middle bargraph segment lights as well
as the SP2 annunciator.
4. Remove the object and replace with the next object to be checked.
The bargraph will show if the weight is under, over or within the target
weight range. If the weight is under, SP1 annunciator and the UNDER
bar segments will light. If the weight is over, SP3 annunciator and the
OVER bar segments will light.
5. Repeat step 4until you are finished weighing items.
The current target weight will be active until you repeat steps 1through 3with a new
item of a different weight.
3.4.5 Setting upper and lower limits
With the indicator in checkweighing mode, follow these steps to set a target by setting
upper and lower limits.
1. Press ZERO to zero the scale, if necessary.
2. Enter a tare if necessary. Refer to Net weighing on page 13 for instructions.
3. With weight inside the gross zero band, press F1 …
Lo will be displayed briefly and then the current value for the lower
accept weight.
4. Press ZERO to accept this or key in a new lower accept weight and press
ZERO …
Hi is briefly displayed and then the current value for the upper accept
weight.
5. Press ZERO to accept this or key in a new upper accept weight and press
ZERO …
The display returns to normal weighing mode.
The acceptable target window is a range from Target Object weight ± a predefined
range entered in a password protected menu.
The farther the weight is from the target weight, more over or under bargraph
segments will light. The UNDER and OVER bargraph segments are fixed at 1 division
each.

20 T401S Indicator User Instructions
Indicator applications
6. Place a weight on the scale …
If the weight is below the lower accept weight, the left bargraph
segments will light.
Any weight between the lower and upper acceptable weights will cause
the middle bargraph segment to light to show the weight is within the
target range.
If the weight is above the upper acceptable weight, the right bargraph
segments will light.
7. Remove the item from the scale and repeat step 6to check other items.
8. To set new upper and lower limits, repeat steps 1through 5.
3.4.6 Setpoint operation in the checkweighing application
Inside the Gross Zero Band = All outputs and annunciators are off.
Under Target or Below Low Accept Weight = SP1 annunciator and Output 1 are on.
Inside Target = SP2 annunciator and Output 2 are on.
Over Target or Above Upper Accept Weight = SP3 annunciator and Output 3 are on.
Outputs have to be enabled (see Service manual).
