POSITION OF ZERO AND GAIN REGULATIONS:
8.5.1 Series LD-LT and Series AP 7000:
The zero and gain regulations are reached thorough a large screwed hole protected by
a sealing screw.
The zero regulation (about ±10% FS) is the nearest to the external enclosure and the
most easy to be reached.
The gain regulation is the most internal one and far from the external enclosure and
difficult to be reached. This regulation is done by DS Europe and it has not to be
touched by the Customer.
Series LD and LT:
When the cell is installed and it has the label on the upper position and the
regulations on the lower position, the zero regulation is the most external on the
right and the only one that may be regulated.
Series AP 7000:
When the cell is installed and the cable is on the upper position the zero
regulation is the most external on the left and the only that may be regulated.
8.5.2 Series 500 QD and 500 QDT: (see the "overall dimensions" of the bulletin)
The zero and gain regulations are reached by separated screwed holes.
As listed in the "overall dimensions" of the bulletin, when the cell is installed, the
cable exits on the left, the two holes are vertically lined up on the right, then the zero
hole is in the upper position. Do not touch the gain regulation on the lower position.
8.5.3 Series ME-MF:
The zero and gain regulations are reached removing the metal cover and the rubber
gasket having unscrewed the 2 fixing screws.
Important: remove only the cover without the central screw (support of the internal
electronics).
Take-away the filler silicon grease and uncover the transparent silicon gel below.
On the printed board are settled 2 multiturn potentiometers.
The zero pot is the nearest to the centre; the gain pot is the most external and it has
not to be regulated.
When the zero regulation is finished, fill entirely by silicon grease the cavity up to
the metal cover to be fixed by the 2 screws.
8.5.3 Series EG:
The zero and gain regulation trimmers can be reached by removing the circular metal
lid, on the load cell.
8.5.4 Series PT500:
The zero and gain regulation trimmers can be reached by removing the rear metal lid
by unscrewing the screws.
8.5.5 Series MP e 560QDT:
The electronics is sealed inside the load cell metal frame and it is not possible to
reach the zero and gain trimmers.
