Setting

1. The zero-reset button is for resetting zero drift. Press and hold the button for 5 seconds to complete the operation.
2. The RS485 terminating resistor (120Ω) is selected by the toggle switch. When "J8" is ON, the resistor (120Ω) is applied.
3. Response Time select: switch the S2 to different positions for 0.5s,1s, 2s and 5s according to the diagram below.
Note: since the time is not fully synchronized, the actual response time is 1~2 times set time.
