Open-Short Tests
Open-Short Test is proceeded in 400Ω resistance mode. 0.4V voltage (relative to AGND) is generated by
internal IC and is output through R22, then is added to open-short measuring point through PTC. J3 and J5 are
mode switches that are close during doing the open-short test. Rx gets voltage VRX, and enters IC through R19.
If Rx is smaller than 50Ω, the buzzer will sound.
