4.2 Parts Counting
Use this application to count samples of uniform weight.
1. In the upper left portion of the home screen, select Parts Counting.
2. Press Tare or Zero if necessary to begin.
3. Establish an Average Piece Weight (APW), the default (or last) APW is displayed.
4. Place objects on the pan to display the number of pieces on Main Display Line.

STX EN-9
APW:
Set a known Average Piece Weight (APW)
To adjust the APW value directly, touch the APW
button.
A numeric input window appears.
Key in the desired APW Weight, then press
Save.
The display returns to the application home
screen with the new APW value in the reference
field.
Samples:

To establish a new APW, touch the Samples
button.
A numeric input window appears.
Key in the desired Sample Size (1 to 10000
pieces), then press Save.
The display returns to the application home
screen. Follow the screen instructions to
establish a new APW.
Place the reference weight on the pan and
press Accept to continue. The sample size
displayed will be used. The new APW value is
shown in the reference field.
The Main screen returns with the new APW
value calculated.
4.3 Percent Weighing

established Reference Weight.
The default (or last) Reference Weight is displayed.
1. In the upper left portion of the home screen, select Percent Weighing.
2. Place an object on the pan. The difference between the sample and the Reference Weight
is displayed as both a weight and a percentage.

The balance calculates water density based on
the water temperature value entered (internal
lookup table). Measure the actual water
temperature using a precision thermometer.
Press Back to return to the Density
Determination home screen.
To begin the Density Determination process,
press Start.
Step 1 of 2 Weigh the Sample in Air.
Press Start. Follow screen instructions, and then press Accept to store the dry sample weight
Step 2 of 2 Weigh the Sample Submerged in the Liquid.
Follow the screen instructions, then press Accept to store the sample weight (submerged in
liquid).

STX EN-15
Once the necessary weights have been
determined, the density of the sample is
displayed in g/cm3(along with the weight
in air, weight in water) on the Application
screen.
Press Start to reset all the weight values and restart the process.
The balance can also be used to measure the Density of a Buoyant Material Using Water.
Follow the same procedure as Solid Material above, except in Density Determination step 2,
push the sample down (requires special tool, not supplied) into the liquid until it is fully
submerged.
4.5.2 Measuring the Density of a Solid Using an Auxiliary Liquid
To enable this feature, enter the Item Settings screen and select the following:
Density Type: Solid
Auxiliary Liquid: Other
Porous Material: Off
Confirm the default values displayed (Liquid Density, etc) are correct.
Begin the Density determination process by pressing Start and following the screen
instructions.
4.5.3 Measuring the Density of a liquid using a Calibrated Sinker (not
supplied)
Enable this feature, enter the Density Item Settings screen and select the following;
Density Type: Liquid
Note: when the Density Type is set to Liquid, the
Liquid type and Porous material selections are
disabled.

EN-16 STX
Confirm that the default value displayed (sinker
volume) is correct. To edit the default values,
touch Sinker Volume.
A numeric input window is displayed.
Key in the desired value, then press Save.
The display returns to the previous screen.
Edit the Liquid temperature if required.
To return to the Density Determination home
screen, touch Back.
Press Start to start the process.
Step 1 of 2 Weigh the Sinker in Air.
Follow the screen instructions, then press
Accept
Step 2 of 2 Weigh the Sinker Submerged
in the Test Liquid.
Follow the screen instructions, then press
Accept to store the sinker weight (submerged
in liquid).
Once the necessary weights have been
determined, the density of the Liquid sample is
displayed in g/cm3(along with the weight in air,
weight in water) on the Application screen.
Press Start to reset all the weight values and
restart the process.
