Use the following 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
Known 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 to
position in this adjustment. Turn the
adjustment switch to
0
- position at the end of the adjustment
•
Turn the programming switch to analog output type position for operation
mode (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.
