CALIBRATION PROCEDURE USING WEIGHTS
It is assumed that the load cell system is connected to the EZE30 and the power is
on. The maximum and minimum display values, display increment size and decimal
point position should be defined prior to carrying out the calibration (See Menu 3).
For this example the display maximum is define as 2009, the display minimum is -
200, the display step size is 1 and there is no decimal point.
a) Go to Menu 1.2 and using the UP/DOWN and RIGHT keys set the display to
read 0000.
Press the key. This defines the
actual zero calibration point.
b) Go to Menu 2.1 and set the display to
read the value of the calibration weight(s) which will be applied. For this
example if the calibration load applied which will be applied is 2000 kg, set the
display to read 2000.
This defines the calibration weight.
Remember that all parameters under sections 1.1 - 1.3, 2.1 - 2.3 and 3.1 - 3.3 can
only be accessed or changed after the Recessed Enable Switch has been pressed.
Make sure that the weighing system is empty or at the point where
you want the display to read zero. 0 [Enter]
using the UP/DOWN and RIGHT keys
Press the 0 [Enter] key.
Example:
3 leg tank or silo fitted with 3 off 1000Kg 2mV/V load cells
Dead load 500Kg, Live range 2000Kg in 1 Kg steps
c) Go to Menu 2.2. Apply the calibration weight(s) to the weighing system. The display will show the actual input signal in
mV/V. The display will now show 2.2. Press the right arrow key twice and
the DAS will be back in weighing mode.
Calibration is now complete
Press the 0 [Enter] key.
Press the 0 [Enter] key. This defines the actual span calibration point.
d) If required the zero can be re-calibrated without affecting the span. To do this make sure that the weighing system is empty or at the point
where you want the display to read zero. Goto Menu 1.2. Press the 0 [Enter] key. The display shows the actual input signal in mV/V. Press the
0 [Enter] key. Press the right arrow key twice and the DAS will be back in weighting mode.
