The Weighingblock is a robust Scale. It is designed for portable use. When
transported by car between different working places we recommend using of a
protected space or a case. This will extend the interval for service.

All setupparametersmaybeenteredviathemembranepanelkeys.TheScalehasan”intelligent”auto power off function and can be operated
with 6 alkaline 1,5 V batteries. 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.
The Weighblok scale can be used as a Batching Scale or regular weighing scale
The Weighblok is suitable for use in weighingapplications as: refrigeration cylinders, fire protection cylinders, CO2,
cylinders, parcels, persons, etc.
Keyboard functions
The calibration switch is only for calibration.

Calibration
We recommend the scale to be calibrated at periodic intervals with the frequency based on usage.
The minimum test weight that can be used is 70% of full-scale capacity.
To adjust the zero point using the F16 zero adjust procedure:
1. Turn the power OFF
2. Put Calibration Switch to the Calibration position.
3. Press the ON key.
4. Scroll to "F 16". Use TARE or ON to move up or down.
5. Press ZERO. The display will momentarily show "C 0" followed by a value. (If you want, press Dot
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 adjust the max point using the F17 span adjusts procedure:
1. Scroll to "F17",then press ZERO to enter spancalibration 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 weight on the Scale.
3. Pressing TARE or ON will change the position of the flashing digit.
4. Increase the flashing digit by pressing Dot. Decrease the flashing digit by pressing ZERO.
5. After setting the exact value, press NETto save the value.
6. Ifthe adjustmentwassuccessful, the displaywill show"EndC1" momentarily, and thenrevert back up to F17.
"Err0"–The calibration test weight or the adjusted keyed-in weight is larger than the full capacity of
the scale. Change the calibration test weight orcheck the input data.
"Err1"–Change the calibration test weight or check the input data.
"Err2"–The internal resolution of the scale is not highenough to accept the calibration value.
Select a larger parameter for the Span Gain (F2).
7. Put the Calibration Switch to the normal mode.
8. Check the Scale.

MEANING / POSSIBLE SOLUTION
rrrrrr
Normal Operating
Mode
Gross Overload. A weight greater than the rated capacity has been applied to the scale. Remove the weight
from the platter or try re-calibrating the scale. 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. Re-charge the battery or replace if alkaline batteries.
Err 0
Span Calibration
Mode (F17)
Keyed-in weight value is larger than full-scalecapacity. Use a smaller test weight or check keyed-in value.
Err 1
Span Calibration
Mode (F17)
Keyed-in weight value is less than 1% of full-scale capacity. Use a larger test weight 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 scale.
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. Indicator 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 Scale.

Troubleshooting
If the Weighblok to power up.
1. Change to new alkaline batteries.
2. Check to see if AC adapter is plugged in.
If thescale startsbut the display showswrong.
1. Adjust and Calibrate the Scale.
Bottom plate removal
1. Remove the two screwsfrom the bottom plate ofthe Weighblok.. Be careful with the keyboard connection.
2. Check the inside of the Scale visually. Look for bad cables and connections.
If the Scale shows F1
1. Check the position of the Calibration Switch.
2. Reset to normal mode.
Loadcell Connections
Check the Loadcellwith a universal voltmeter, see table. The left pin is number 1.

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.

Weighblok Enunciator Definitions. Shown above is the LCD display. Before readingthe value the stable indicator must be ”on”.
Ifnot, wait a few secondsuntil it appears.
Basic scale use
1. Press ON to start the scale.
2. If necessary, press ZERO to obtain a weight reading of zero.
3. Press OFF to switch off the scale. Hold 3 seconds.
4. The scale switches off automatically after 10 minutes when not in use
Weighing (e.g. a cylinder with liquid)
1. Unload scale and press ZERO.
2. Place the object (cylinder, container, etc) on the scale’s platter and allow the weight indication to stabilize. If the item
weight exceeds the scale’s weight capacity, it displays “rrrrrr”. Press TARE to zero the Scale. The display
shows zero weight and turns the NET enunciator on.
3. NET/GROSS toggles between Gross and Net weight display only if a Tare has been established.
4. “Dot”.Extended graduation.
General advice
When the Scale is not in use and is transported between different working places, we recommend usage of a case or any
other protection against vibrations and other hard environmental conditions. Protect the scale with a plastic bag if there is
any risk of working in a wet environment.
