ｓ As shown in below, output impedance Ro is 330Ω.

The value of Vh high level of output voltage is determined according to the ratio of the resistance to Ri input impedance to connect.

Please calculate Vh voltage from Ri input impedance to connect and check whether the Vh is appropriate before you use.

The output value will be Vh when the MP-981 accepts the signal from the top of the detection gear.
