10-4. D/A Converter
The D/A converter is an interface to output measured weight values as electrical signals. Current in
proportion to the weight value (4mA ~ 20mA) can be output.
The over range is ±5% of the full scale.
10-4-1. Name of Each Part
- Gain fine trim potentiometer
For fine adjustment of gain. Trimmer adjusts output to
20.00mA for full scale.
Gain can be adjusted through the front panel as well.
- Zero fine trim potentiometer
For fine adjustment of zero. Trimmer adjusts output to
4.00mA for zero.
Zero can be adjusted through the front panel as well.
The terminals for current output of 4 ~ 20mA. Connect an
instrument whose load resistance is less than 350 Ω.
- Current output terminals
The trimmer is for fine adjustment.
Temperature drift may increase if you have severely changed the value that
had been set when you first received the product, please adjust it within a
range of ±0.2mA.
Request
- Pick up the plug then handle the lever with
