Enter the weighing
system mV/V value CALIBRATE THE SPAN FROM THE LOAD CELL mV/V READING
If you are calibrating the weighing system without weights, use this menu point
to enter the mV/V value for the weighing system. The weighing system mV/V
value can be derived from the load cell test data. Normally a test data
certificate is provided with each load cell stating amongst other things, the
Output at Rated Load (ORL) in mV/V. In single load cell applications the
weighing system mV/V value will be the load cell ORL value. In applications
using more than one load cell, the weighing system mV/V value will be the
average of the individual load cells ORLs. Normally load cells used in multi-cell
applications have matched or rationalized ORLs typically 2 or 3 mV/V for
example. So if you have 4 load cells in your system, each 1000 kg capacity
with ORLs of 2 mV/V then the weighing system capacity will be 4000 kg at 2
mV/V. Use the UP/DOWN & MOVE RIGHT keys to enter the weighing system
ORL reading in mV/V. The reading should be in the format x.xxxx e.g 2.0000 if
the ORL is 2 mV/V exactly. The corresponding weighing system capacity should
be entered in menu point 2.1

ZERO BUTTON ENABLE (± 20% of DISPLAY MAX) / ZERO TRACK RANGE (± 255 d).
Use this menu point to enable or disable the zero button and to set the zero track range. If this parameter is set to
0 then the zero button and the zero tracking will be disabled. If this parameter is set between 1 and 255, the zero
button will be enabled and the zero track range will be equal to the number set. Use the UP/DOWN & MOVE
RIGHT keys to set the zero track range and store by pressing the enter key. Factory default value 00001.
In the normal weighing mode, the zero button will set a new zero providing that the displayed weight value is less
than ± 20% of the maximum display value (see Menu 3.1 o). So if for instance, the maximum display value is set
to 10,000 [Factory Default] the maximum display value that can be set to zero using this button is ± 20% of 10,000
i.e. ± 2000 display counts. If you try to set a new zero which is greater than ± 20% of the display maximum you will
see the error message ‘Err 2’ on the display. To overcome this problem you can either re-calibrate the zero using
Menu 1.2 or 1.3 or you can increase the display maximum (Menu 3.1.o) to allow higher offsets to be corrected.
If this parameter is set between 1 and 255 (not 0) then the zero tracking will also be enabled. The value set will be
equivalent to the zero track range (plus and minus around zero). The zero tracking will work on the no load or zero
value of the weighing system to bring it back to exactly 0. If for instance the no load value or zero of the weighing
system comes back to 5d when unloaded (due to product build up in the weigh hopper for instance), the zero
tracking will automatically reduce this zero offset back to zero providing that the zero is stable (no motion) and is
inside the zero track range. The no load output will be reduced at a fixed rate of 0.4 d/second until the value
reaches 0. The value of d is equal to the display step size.

Use the UP/DOWN & MOVE RIGHT keys to enter the weighing system ORL reading in mV/V. The reading

MENU 4.3 UPDATE RATE - DEFINES HOW MANY MEASUREMENTS ARE USED TO CALCULATE AN AVERAGE
This section refers to Menu points 4.1 - 4.3.
Setting the filter level to 0 will disable the filters
in either modes (0 or 1). The Gaussian filter type
IIR (mode 0) filter level 4 is the factory default.
This provides a slower response with a high
level of damping. The FIR filter type provides
better response where high speed is required.
Both types of filter can be enhanced further by
using the UR parameter Menu 4.3 to average
between 1 (UR=0) and 128 (UR=7)
measurements.

2SET THE WEIGHT VALUE AT WHICH 4 mA IS SENT
Use the UP/DOWN & MOVE RIGHT keys to set the weight value at which 4 mAis sent. This typically will be set to
zero, so that when the display reads zero weight, 4 mA will be sent down the analogue output. If you want the
analogue output to run between 0 mA and 20 mA, you will need to calculate what the 4 mA value will be and store
it here. To do this take the difference between the weight value at 20 mAand the weight value at 0 mAand divide it
by the 20 and multiply by 4. For example if the analogue output is 0 - 20 mA for 0 - 1000 kg then the 4 mAvalue will
be 1000/20*4 = 200.

2TEST MODE FOR THE CURRENT OUTPUT (Range 0mA - 21mA)
Use the UP or DOWN & MOVE RIGHT key to set a current value in mA, which will be sent down the
analogue output, independent of the load applied to the weighting system. If values below 0mA are selected
the DAS will send its minimum value (0mA) until a value within its normal range is selected. Similarly if
values above 21mA are selected then the DAS will send its maximum value (21mA) until a value within its
normal range is selected.

SET THE WEIGHT VALUE AT WHICH 20 mA IS SENT.
Use the UP/DOWN & MOVE RIGHT keys to set the weight value at which 20 mA is sent. Typically this will
be set to the weight value at which you want 20 mA to be sent down the analogue output.
