1.4 Basic Operation
1.4.1 Power
Press and hold the ON/OFF key, shown below, for two seconds to power on or
off the indicator. After a self-test, normal weighing mode will be accessed.
1.4.2 Zero Operation
Initial Zero Setting During power up, if the weight on the scale is
within the initial zero tolerance, the indicator will
show zero automatically. The center of zero and
stable annunciators will be lit.
Pushbutton Zero When the scale is stable and not showing a
negative weight, you can zero the weight, within
tolerance, by pressing the Zero key, shown
below.
1.4.3 Tare Operation
When a gross weight is tared, the indicator will show the net weight. The Net
and Tare annunciators will light.
In tare mode, press the Tare key to clear the tare weight and the indicator will
show the gross weight.
1.4.4 Print
If the weight is stable, press the Print key to print the weight to a connected
printer.

1.5 Counting Function
Follow these steps to count items of the same weight.
1.5.1 Getting a Piece Weight
1. While in the weighing mode, press the Zero key to clear weight from the
scale.
2. Load pre-counted sample pieces of (5, 10, 20, 50, 100, 200, or 500) on
the scale and press the Count key.
PCS 0 is displayed.
3. Using the Zero key, select from the quantity choices (5, 10, 20, 50,
100, 200, 500).
4. Press the Print key to select the displayed choice.
The quantity of items is shown.
5. Remove the sample pieces and zero the scale if necessary.
6. Load the items to be counted on the scale.
The quantity of items is shown.
7. Press the Count key to return to weighing mode.
If you want to weigh items with a different piece weight you must turn the unit
off and on again and then repeat steps 1 through 7.

9
1.6 Accumulation Operation
1. With 0 on the display, add the weight to the scale. Press the Total key
to enter the accumulation mode.
The Total annunciator turns on and the display shows n 001,
and then the display goes back to the loaded weight.
2. Unload the weight.
The display shows 0.
3. Load the second weight and press the Total key.
n 002 is displayed then the display goes back to the loaded
weight.
4. Repeat the previous steps for a maximum 999 times.
Viewing the Accumulation
1. To view the values during accumulation, press and hold Total and ON/
OFF keys.
nnn is displayed and then the total accumulated weight is
displayed. nnn is the number of accumulations included in the
total weight.
2. If the total weight is beyond the display capability, it will show the first
4 digits then the last 4 digits. For example, the first four digits are 0012
and the last 4 digits are 34.56, the actual weight is 1234.56.
Clearing the Accumulated Weight
Follow these steps to exit the accumulation function:
1. While the display shows the last 4 digits of the accumulated weight,
press and hold the Total key.
clr n is displayed. This prompt means Clear the accumulated
weight? - No.
2. Press Zero or Tare to toggle between clr n and clr y which means
Clear accumulated weight? - Yes.

10
3. When the desired choice is displayed, press the Print key to accept
that choice.
If you choose clr n, the indicator exits the accumulation mode
without clearing the total weight. If you choose clr y, the total
weight is cleared and the indicator exits accumulation mode.

1.7 Calibration and Parameter Setting
The Parameter menu is divided into a calibration section and a parameter
configuration section. To enter the parameter part of the menu, follow step 1
below. To enter the calibration plus the parameter section, follow step 2 below.
You may need access to the Seal switch on the main board, shown in the photo
below.
1. For access to the parameter section only, the Seal switch must be in the
OFF position. Press and hold the Print and Total keys.
This accesses the menu section numbered C08-C39.
2. For access to both the calibration and parameter sections, the Seal
switch must be in the ON position. Press and hold the Print and Total
keys.
This accesses the complete menu numbered C01-C39.
CAUTION: If you break the official seal to open
the back of the indicator you may need to have
the indicator recertified by local weights and
measures officials. Open the back only if you are
sure it is correct to do so.

1.7.1 Calibration Instructions
When initial installation or recalibration are necessary, locate the seal switch
and place it in the ON position.
Follow the calibration steps. Press and hold the Print and Total keys to access
the calibration menu. Below are the seven calibration parameters.
The SBI-505 requires a minimum of 10% of the
configured scale capacity in dead weight to calibrate
the indicator.
