Adjusting The Internal Reference Weight (Scs Only) - Precisa 320 XT Serviceanleitung

320 XT/XB/IP65

5.12 Adjusting the internal reference weight (SCS only)

It is possible to vary the full load reference weight within particular step sizes which may be,
according to your actual balance, 10, 50, 100 or 500g. This allows an adjustment wether with
various reference weights at disposal or close to the usual operating range of the balance.
IMPORTANT:
Ensure the reference weight lays within the range of +/- 0.3d of its nominal value!
Example:
A 4200C of a customer, who usually weighs loads of 2.8kg, asks for 2000g. Its refe-
rence weight step size is 500g. A reference weight of 3000g (2000g + 2 steps of 500g) is the
closest to the usual operating range.
the range of 2999.997g .. 3000.003g (maximum deviation = +/- 0.3d = +/- 0.003g at
d=0.01g, see specifications).
1. Ensure the balance has reached its operating temperature and is in service mode:
XT:
see "Setting the balance to the service mode (XT only)" on page 73.
XB:
see "Setting the balance to the service mode (XB only)" on page 73.
2. Have, according to the specifications, a suitable full load reference weight at disposal.
3. Hold TARE until „CALIBRATION"/„ADJUSTMENT" appears → the balance starts carrying out
an internal adjustment without setting the obtained correction factors, starts thereupon with
the external adjustment and asks, as soon the zero point is measured, for the reference
weight. Its value is displayed flashing.
4. Place the asked weight, or better, the one placed at disposal → the balance catches its value
and the display flashes. As soon as the flashing stops, the balance asks for the zero point.
This is displayed flashing: „-- 0000 g".
5. Remove the weight → the balance continues with the external adjustment, determines newly
the correction factors for the internal reference weight, carries out immediately an internal
adjustment and finally turns itself off and on, in order to quit the service mode.
