-This 2-position slider switch is only accessible by removing the right side panel (see above) and sets whether the AUXILIARY OUTPUT SERVO is unipolar or bipolar. It is factory set to be bipolar so the auxiliary output can range from -12 V to +12 V.  For some applications such as driving a PZT, limiting the voltage range to positive values is necessary. ​ When this switch is in the unipolar mode, the auxiliary output ranges from -0.5 V to +12 V. Additionally,​ when in Ramp->​Aux mode and Aux: Unipolar, the ramp is centered at ~3.5V instead of 0V.+This 2-position slider switch is only accessible by removing the right side panel (see above) and sets whether the AUXILIARY OUTPUT SERVO is unipolar or bipolar.
