MODE SELECTION SWITCH BANK (SW-2)
1. For CURRENT INPUT turn switch one ON. For VOLTAGE INPUT turn switch one OFF.
2. For UNI-POLAR INPUT (low end of scale ≥ zero) turn switch two ON and turn switch three OFF.
3. For Bi-POLAR INPUT (low end of scale < zero) turn switch two OFF and turn switch three ON.
4. For ZERO BASED INPUT (eg. 0 TO 20 mA) turn switch four OFF.
5. For ZERO SUPPRESSION (eg. 4 TO 20 mA) turn switch four ON.
