SET THE WEIGHT VALUE AT WHICH 4 mA IS SENT
Use the UP/DOWN & MOVE RIGHT keys to set the weight value at which 4 mA is 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 mA and the weight value at 0 mA and 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 mA value will
be 1000/20*4 = 200.

2 TEST 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.

SET THE ANALOGUE OUTPUT BASE (groS, nEt [Default], PEA, AUEr, HoLd, PP, UALL, dISP, oFF)
Use the UP or DOWN key to set which parameter the analogue output will follow : groS - the analogue
output follows the Gross value: nEt - the analogue output follows the Net value : PEA - the analogue output
follows the Peak value: AUEr - the analogue output follows the Average value: HOLd - the analogue output
follows the Hold value: PP - the analogue output follows the Peak to Peak value: UALL - the analogue
output follows the Valley value: dISP - the analogue output follows the value shown on the display: oFF -
the analogue output is switched off.
