SAFETY PRECAUTION
The integrated circuits used in this equipment are highly immune to noise and RFI when properly installed
in the unit.
The terminal on the rear panel must be grounded directly, not with the AC ground.
Therefore, when shipping please always use original packing (conductive material) for shiping. Remove
equipment from the shopping container and examine the external surfaces of the equipment for physical
damage.
The A 810 should be positioned in a safe area with no combustible gas, the operating temperature is
+14°F to 104°F (-10°C to +40°C), storage temperature -28°F to 185°F (-20°C to +85°C)
Confirm the AC voltage of all equipment before power-up. The A 810 can operate within a -15% to + 10%
voltage variation.

3. How to get started
At delivery the A810 is preset on default parameters (comply with legal-for-trade) to operate as a simple
scale provided the resolution is set and the calibration has been carried out.
The following section explains how to setup the instrument according the required function by using the
front panel keypad and display.
As an option a sophisticated Windows® based setup program is available to make the adjustment easier
and faster. Via PC-Programm all parameter can be saved for backup in a separate file, the print image is
changable and A810 can send weighing- and status-strings to PC via commands (see separate
information).

Manual of Weighing Controller A 810
3.1.1.11. Stable number “StAN”
Set in terms of numbers in the range
between values from 10 … 250.
This value defines the number of
averaged ADC values taken into account
for testing the stable condition.
A higher number provides a safer stable
condition but it also extends the minimum
time necessary to recognize the stable
condition after a load has been changed.
default setting: 50
3.1.1.12. Stable range “StAR”
Set in terms of tenth of a division in the
range of 1 to 255.
This value defines the range of tolerance
a weighing sample has match in order to
meet the stable condition.
A higher value provides a safer and
faster stable condition.
default setting: 10
3.1.1.13. Limit underload “LUNL”
Set in terms of divisions in the range of
0 to 1000.
This value defines the number of divisions
below zero that have to be indicated
before the underload message has been
generated.
default setting: 9
3.1.1.14. Limit overload “LOVL”
Set in terms of divisions in the range of
0 to 1000.
This value defines the number of divisions
above FS (max.) that have to be indicated
before the overload message has been
generated.
default setting: 9
