2.6.1 Soldered Jumper
For the output -10 +10 V and -5 +5 V the soldered jumper (SW4)
must be closed:
• Release the locking tabs, both sides, to open the
enclosure.
• Locate the soldered jumper (SW4), on the circuit board.
See Figure 2-6 on page 20 .
• Close the jumper shorting the pads with a solder bridge.
2.6.2 Analog Output Type Scale Corrections
Note
Minimum and maximum values which can be set for the zero and
full scale corrections Refer to  and  .
The analog output may also be used in the opposite manner, where, the weight setting that corresponds to the
analog zero (  ) may be greater than the weight set for the analog full scale (  ). The analog output will
increase towards full scale as the weight decreases; the analog output will decrease as the weight increases.
Example: analog output type having selected 0-10V
 = 10000  = 0
Weight = 0 kg analog output = 10 V
Weight = 5000 kg analog output = 5 V
Weight = 10000 kg analog output = 0 V


-- Analog output correction to zero: if necessary adjust the analog output, allowing the PLC to indicate 0. The sign ‘-‘ can be
set for the last digit on the left.
Example: for a 4-20 mA output and a minimum analog setting, the PLC or tester reads 4.1 mA. Set the parameter to 3.9 to
obtain 4.0 on the PLC or tester. See Analog Output Type Scale Corrections for additional information.
 -- Full scale analog output correction: if necessary adjust the analog output, allowing the PLC to indicate the value set in the
parameter.
Example: for a 4-20 mA output with the analog set to full scale and the PLC or tester reads 19.9 mA, set the parameter to
20.1 to obtain 20.0 on the PLC or tester. See Analog Output Type Scale Corrections for additional information.
