Introduction
Veteks new VB2 series of Weighingblocks are rugged digital Force Meter made in strong aluminum. It comes standard with a large
(.75") LCD screen for easy readout. All setup parameters may be entered via the membrane panel keys. The Force Meter has an
”intelligent” auto power off function.
The Force Meter is developed for general force measuring The setup parameters are altered through the Setup menu while a
few other parameters are altered through the User menu. The configuration section of the manual explains how to use
the five front panel keys to maneuver and save settings in both menus.
The Force Meter is equipped with 9 V alkaline battery. If the battery is not good enough to ensure a correct value the
Force Meter will turn off.
Keyboard functions
The calibration switch besides the battery is only for calibration.
Indicator ON
Normally disabled.
Toggles between Gross and Net weight/force display only if a Tare has been established.
Sets Force Meter to display "0" when in Gross mode, and within zero band range. When pushed in
for 3 seconds, the Force Meter switches off.
Used to establish a Tare (zero the Force Meter) while in either Gross mode or
Net mode. This operation cannot be performed at or below Gross zero.

Configuration
Setup menu.
To do this configuration you need to have a good acknowledge how a digital electronic Force Meter works. Note: If the
Force Meter fails, it is not always sure the Force Meter needs a configuration.
Except the Normal Meny the Weighingblock has two menus.
The Setup menu, containing most of the indicator's functional Setup parameters, consists of 15 separate menu selections, each with its own
sub-menu of choices.
The User menu, except A5 and A10 containing most of the indicator's serial communication parameters which not are shown in this
manual.
SETUP MENY
1. Turn the power OFF.
2. Press Calibration Switch one time.
3. Turn the indicator ON.

Calibration
We recommend the Force Meter to be calibrated at yearly intervals.
The minimum test force that can be used is 70% of full-Force Meter capacity.
To calibrate the zero point using the F16 zero calibration procedure:
1. Turn the power OFF
2. Press the Calibration Switch once.
3. Turn the power ON and the display will show F1, if not go back to point 1.
4. Scroll to "F 16". Use the TARE or PRINT key to move up or down. (If necessary press O to go back
to parameter number.)
5. Press ZERO. The display will momentarily show "C 0" followed by a value. (If necessary press O to
go back to parameter number.)
6. After making sure that there are no weights on the platform, press ZERO to zero out the displayed
value.
7. Press NET to save the zero point value. The display will show "EndC0"momentarily, and then revert
back up to F16. At this time, proceed to the F17 span calibration to complete indicator calibration.
To calibrate the max point using the F17 span calibration procedure:
1. Scroll to "F 17", then press ZERO to enter span calibration menu.
2. The display will momentarily show "C 1" for the span calibration, followed by a value with one flashing digit. This
value will be zero. Place the test force on the Force Meter.
3. Pressing TARE or ON will change the position of the flashing digit.
4. Increase the flashing digit by pressing O. Decrease the flashing digit by pressing ZERO.
5. After setting the exact value, press NET to save the value.
6. If the calibration was successful, the display will show "EndC1" momentarily, and then revert back up to F17.
"Err0" – The calibration test force or the adjusted keyed-in weight is larger than the full capacity of
the Force Meter. Change the calibration test force or check the input data.
"Err1" – Change the calibration test force or check the input data.
"Err2" – The internal resolution of the Force Meter is not high enough to accept the calibration value.
Select a larger parameter for the Span Gain (F2).
7. Press Calibration Switch one time for normal mode.

CODE MODE MEANING / POSSIBLE SOLUTION
 Normal Operating
Mode
Gross Overload. A force greater than the rated capacity has been applied to the Force Meter. Remove the
force from the platter or try re-calibrating the Force Meter. Otherwise, check for a bad load cell connection
or possible load cell damage due to overloading.
bAtt Normal Operating
Mode
Indicates a low battery condition.
Err 0 Span Calibration
Mode (F17)
Keyed-in force value is larger than full-Force Meter capacity. Use a smaller test force or check keyed-in
value.
Err 1 Span Calibration
Mode (F17)
Keyed-in force value is less than 1% of full-Force Meter capacity. Use a larger test force or check keyed-in
value.
Err 2 Span Calibration
Mode (F17)
There is not enough load cell signal to produce the internal counts necessary to properly calibrate the Force
Meter. First check all load connections. Use F16 mode to view internal counts. See Appendix C for more
information.
Err 3 All Modes Non-volatile memory read error. One or more setup parameters have been lost.
Err 4 All Modes Non-volatile memory writes error. The unit needs service.
Err 5 Key-in Span
Calibration Mode
(F20)
You have attempted to enter a zero value for C1. Enter a known calibration value greater than zero.
Err 7 Initialization No reading from the ADC. Make sure there is a load cell(s) connected to the indicator at start-up.
Err 9 Normal Operating
Mode
Span calibration value has been lost. Re-calibrate the Force Meter.

Fault localization and repair.
Fault localization
If the Weighingblock is “dead”.
1. Check the battery. Use only a 9 V alkaline battery.
If the Force Meter starts but the display shows wrong.
1. Calibrate the Force Meter.
2. If it not works.
3. The Force Meter must be demounted.
Demounting.
1. Demount the Weighingblock carefully.
2. Check the inside visually. Look for bad cables and connections.
3. If needed, clean the PC-board.
If the Force Meter shows F1
1. Probably has the Calibration Switch been changed to calibration mode?
2. Reset to normal mode.
3. Press OFF and ON.
Check the Loadcell
1. Check the Loadcell with a universal volt instrument, see encl table. The pin close to the corner is number 1.
Pin Description
1 Out +5VDC
2 In +
3 Out 0 VDC
4 In -
If some parameters by mistake has been changed.
1. If only the first,F1, has been changed. Set back to right value in accordance to the table.
2. If many parameters has been changed. Check all parameter values. Probably it is necessary to calibrate
the Weighingblock.
Check the excitation voltage, it should be aprox 5 VDC.
The output from the Loadcell (pin 2 and 4) will increase from
aprox. 0 to 10 mV for the capacity range.

Enunciator
MEANING
0Better known as the “Center of Zero” enunciator, this light is active
whenever the displayed weight is within ± 0.25 divisions of true zero.
N Indicates that the indicator is displaying net weight/force.
G Indicates that the indicator is displaying gross weight/force.
T Indicates that a tare weight/force has been established in the system.
Lb/kg Indicates the unit of the displayed weight/force (normally disabled).
bAtt Indicates a low battery condition. Replace the alkaline battery.
Indicates stable weighing.
VB2 Enunciator Definitions Shown above is the LCD display. Before reading the value the stable indicator must be ”on”.
If not wait a fewseconds until it appears.
Handling
1. Press ON to start the Force Meter.
2. If necessary, press ZERO to obtain a weight/force reading of zero.
3. Press OFF to switch off the Force Meter. Hold 3 seconds.
4. The Force Meter switches off automatically after 20 minutes when not in use
Force measuring.
1. Unload Force Meter and press ZERO.
2. Place the object on the Force Meter’s platter and allow the force indication to stabilize. If the item force exceeds the
Force Meter’s capacity, it displays “”. Press TARE to zero the Force Meter. The display shows zero force
and turns the NET enunciator on.
3. NET/GROSS toggles between Gross and Net weight/force display only if a Tare has been established.
General advice
When the Force Meter is not in use and is transported between different working places we recommend to use a case or any
other protection against vibrations and other hard environmental conditions. Protect the Force Meter with a transparent
plastic bag if there is any risk of leakage or when working in a wet environment.
