INSTALLATION MANUAL DD700
Removing the weights in inverse order samples the descent.
The procedure (indicated on the display) is the same as for sampling the Full
Scale Zero, with the only difference that, in this case, more than one point must
be sampled.
Zero sampling
Zero sampling is necessary whenever the scale has already been calibrated and
the zero value has moved when the unit switches on. This can happen when the
preset tare is not known exactly at the moment of the first sampling, or when an
unexpected weight is on the scale. No sample weight needs to be available.
The procedure to follow is indicated on the display.
Inverse
sampling
Inverse sampling can be useful in some cases when it is difficult to load and
unload the known weight from the weighing device, for example in hoppers or
batching systems.
The procedure to follow is indicated on the display.
1.3.2
Setup Menu/Scale/Sampling/View data
See the Customisation chapter in the advanced user manual.
1.3.3
Setup Menu/Scale/Sampling/Correction
This option allows you to correct sampling without needing to repeat the procedure.
Depending on the data available, the correction can be calculated in the different ways explained
below.
Weight
Editor
If known, the weight correction can be set directly.
The set value must be within the range:
- (Capacity/100) <Weight < + (Capacity/100)
Gravity
Editor
sampling site
By selecting Campogalliano (headquarters of the Manufacturer) the gravity
acceleration value of Campogalliano (9.80552 m/s) is set automatically.
Otherwise you may set a gravity acceleration value within the range (9.60000 ÷
10.00000) m/s
.
.
destination site
Knowing the gravity acceleration of the sampling site, you must know the gravity
acceleration of the destination site to calculate the weight correction. You may
set a value within the range (9.60000 ÷ 10.00000) m/s.
Otherwise, the gravity acceleration value can be set as the Coordinates of the
destination site: latitude (0 ÷ 90)° and altitude (-1000 ÷ +9000) m.
Based on the data entered, the program calculates the weight correction and
enters the value obtained in the Weight parameter.
