Use the formula for calculating the analog output value
Analog
Output
=
Minimum output
+
Maximum output – Minimum output
*
Load
Scale capacity
Example:
Scale capacity 100kg
Output range 4 – 20 mA
Load 25kg
The 4-20mA analog output current will be at 25kg ;
I
out
= 4mA + (( 20mA – 4mA ) / 100kg ) * 25kg = 4 + 0.16 * 25 =
I
out
= 8mA
The 0 – 10VDC analog output voltage will be at 25kg:
V
out
= 0 + (10V / 100kg ) * 25kg = 0,1 * 25 =
V
out
= 2.5VDC
 Turn the adjustment switch to the G position from the analog output type
position you set before.
 Increase or decrease the analog output by adjustment rotary switch to the
calculated output value.
Never bring the adjustment switch position to position in this adjustment.
The adjustment switch must be at 0 - position at the end of the adjustment.
 Turn the programming switch to analog output type position for operation
(to V or I).
Important note: The instrument saves 4 different adjustments in its memory for the
voltage and current outputs and their ranges. Changing the analog output type it
automatically set the adjustment to the output range used before.
