either unipolar or may be bipolar. Unipolar analog input voltage range of O-lOV or 0-20V} bipolar input voltage range is 5v or 20V. When unipolar input should BIP OFF Termination ov. A circuit connection shown in FIG. Figure BIP OFF side through the 100n electrical grounding resistance by RP1 can also be zero adjustment. When bipolar input, BIP OFF + lov termination voltage, circuit connection shown in Figure b. Circuit BIP OFF end by 1000 and the resistor RP2 REF, OU end rhyme + 10V voltage connections
