Introduction
Veteks new VB2 series of Weighingblocks are rugged digital scale casted 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 Scale has an ”intelligent” auto
power off function and is equipped with 6 pcs alkaline 1,5 V batteries LR6/AA. If the battery is not good enough to ensure a
correct value the scale will turn off.
The scale is developed especially for weighing of refrigerant cylinders, and to control when transferring refrigerants to other cylinders or
equipments. The scales 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.
There are categories of Scales: Non - Automatic weighing instruments and Automatic weighing instruments.
Weighingblocks and other Scales used only for weighing e.g. cylinders are Non - Automatic weighing instruments. When
using a Non - Automatic scale in commercial purpose in any of the EC countries it is prescribed by law that the scale
must be EC-type approved. If the purpose not is commercial or the Scale is used as an automatic batching Scale there is
no legal demands.
If the Scale is used as a Batching Scale it is an Automatic weighing instruments and there is no legal demands. But this
has to be checked with the authorities in each country.
VB2 series of EC-type approved Weighingblocks:
The parameters shall not ever be changed because of the approval. Authority must do the verification. The user needs a good acknowledge
about all rules and the laws. To get complete information we recommend taking a look at http://www.sp.se or other authorities web sites.
VB2 series of not approved Weighingblocks:
Cannot be verified
The Weighingblocks are suitable for use in weighing applications as: refrigeration cylinders, fire protection
cylinders, CO2, cylinders, parcels, persons, etc.
Keyboard functions
The calibration switch is only for calibration.

Fault localization
If the Weighingblock is “dead”.
1. Change to new alkaline batteries.
2. Change the membrane key buttons if you have reason to believe it’s broken.
If the Scale starts but the display shows wrong.
1. Adjust and Calibrate the Scale.
2. If it not works, the Scale must be demounted.
Demounting.
1. Demount the bottom plate of the Weighingblock trough the two screws covered by a piece of tape. Be
careful with the keyboard connection.
2. Check the inside of the Scale visually. Look for bad cables and connections.
3. If needed, clean the PC-board.
If the Scale shows F1
1. Probably the Calibration Switch has been changed to calibration mode?
2. Reset to normal mode.
Check the Loadcell
Check the Loadcell with a universal volt instrument, see table. The left pin is number 1.
If it is problem to get a reading on the display or it is important to calibrate.
1. Check the excitation voltage (E+ and E-) from the Indicator. Should be 5,0* (+-0,4) VDC.
2. Check the input to the Indicator (S+ and S-). The output from the Loadcell S+ and S- (pin 2
and 4) will increase from aprox. 0 to 10 mV analogue to the capacity range (100 or 30 kg).
Note S+ is plus and S- is minus. The polarity is important.
3. If the input is wrong, <0 mV or > +10 mV with unloaded Scale check the Loadcell. Do have
only E+ and E- connected (or probably an external Power 5 VDC) and checks the output
from the Loadcells direct on the wires. Should be 0 mV to +10 mV depending on the load.
