5-4-3I OP -06 Electric current (4 -20mA) Analog Out
* The voltage output occurs proportionally the voltage according to the size of a weight
In 4mA ~20mA.
* The type of voltage output can be changed according to SET UP F60

▩ Adjustment
* The resistor must be used with enough power consumption.
If you used 500 ohm resistor,
2
W = i R = (0.02)
So,the rate of resistor must be used over than 1/2 watt by 0.2 watt power
* Absolutly do not connect above Lo(-) line to GND line,body GND
Or any similar devices.
▩ How to calibrate for output rate bewteen 4mA and 20mA.
The current out is to 4 mA when the weight is displayed 0 kg in indicator.
The current out is to 20 mA when the weight is displayed max.capacity in indicator.
If analog output is not correct,
You can make a fine adjustment with VR1(zero adjustment) and VR2(span adjustment)
On analog pc board by multi meter.
