Thank You!
Thank you for purchase A.S.T. products!
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.

1.10.22 (May 11): signal output B21 used in sequence-mode; generation of Err109 due to
missing confirmation signal at input pins D18 or D19 (with user function
“230” associated); detailed description of signal input D18/19 at page 65;
change of picture “PC-Interface” at page 88; new parameter “SPFix” in
menu “DAC” for constant analog output at setpoints SP1, SP2 and CPS
1.10-21 (November 10): Interface: USB as option
1.10-20 (September 10): graphics of frontdesign and rear-panel changed due to constructive
reasons
1.10-19 (January 10): due to change of processor, sample rate of 400/s is selectable
(Firmware-Version V.32)
1.10-18 (June 09): due to Firmware-Update to V.31 default parameter dISP-R changed
(faster display rate)
1.10-17 (June 09): due to Firmware-Update to V.30 parameter dISP-R added (display rate
selectable)
1.10-16 (May 08): description Err 129 added
1.10-15 (March 08): refresh rate of I/O added
1.10-14 (January 08): additional operating functions added
1.10-13 (November 07): description of “dAC” changed

The front panel contains a 7 digit numeric display, a two digit alphanumeric display, a multiple status
display and 16 key membrane pad.
Legal-for-trade weighing parameter information is available in a separate window (Descriptive marking).
1.1.1. Numeric Display
The seven digit large size display allows showing a six digit weighing value and an additional plus / minus
character. This display is used for weighing values like Gross, Net, Tare, accumulation values and setup
values as well as Error messages.
1.1.2. Unit Display
This two digit unit display is used for units in weighing mode and for alphanumeric information in setting
mode.
1.1.3. Status display
SP3 : Turns on, if the weighing value has reached “FINAL” – “CPS” and the desired output
signal at the rear panel is active on.
SP2 : Turns on, if the weighing value has reached “FINAL” - “SetPoint2” and the desired
output signal at the rear panel is active on.
SP1 : Turns on, if the weighing value has reached “FINAL” - “SetPoint1” and the desired
output signal at the rear panel is active on.
KEY : Turns on, if the calibration lock is enabled.
ZT : Turns on, if zero tracking is in operation.
ZALM : Starts flashing if zero drift exceeds the Digital Zero limit.
