INTRODUCTION
Vetek’s new VB2 series of Weighingblocks are rugged digital scales cast in strong aluminum. The scales
come standard with a large (.75”) LCD screen for easy readout. All setup parameters may be entered via
the membrane panel keys. The scales have an ”intelligent” auto power off function and is equipped with
6 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 the weighing of refrigerant cylinders, and to use as a
control when transferring refrigerants to other cylinders or equipment.
The scales setup parameters are altered through the Setup menu while a few other parameters are
altered through the User menu. The conguration section of the manual explains how to use the ve
front panel keys to maneuver and save settings in both menus.
There are several categories of scales: Non - Automatic weighing instruments and Automatic weighing
instruments. Weighingblocks and other scales used only for weighing for example, 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 of use
is not commercial, or if the scale’s intended use is as an automatic batching scale then there are no
legal demands.
If the Scale is used as a Batching Scale it is therefore an Automatic weighing instruments and there are
no legal demands. This however requires to be checked with the authorities in each country.
VB2 SERIES OF EC-TYPE APPROVED WEIGHINGBLOCKS: The parameters should not be changed because of
its approval. Only accepted authorities may do the verication. The user requires a good knowledge of
all concerning rules and laws. To get complete information we recommend vsiting the following website
http://www.sp.se ,or visiting other authorities’ web sites.
VB2 SERIES OF NOT APPROVED WEIGHINGBLOCKS: Cannot be veried.
The Weighingblocks are suitable for use in various weighing applications such as the weighing of:
refrigeration cylinders, re protection cylinders, CO2, cylinders, parcels, persons, etc.

FAULT LOCALIZATION AND REPAIR
*PLEASE NOTE: IF A VERIFIED SCALE IS REPAIRED IT PROBABLY NEEDS A NEW VERIFICATION, CHECK WITH
AUTHORITIES IN YOUR COUNTRY.
FAULT LOCALIZATION
IF THE WEIGHINGBLOCK IS “DEAD”
Change to new alkaline batteries.1.
Change the membrane key buttons if you have reason to believe it’s broken.2.
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. Have only E+ and E-
connected (or probably an external Power 5 VDC) and check the output from the Loadcells directly on the
wires. Output should be 0 mV to +10 mV depending on the load.
