First parameter in the signal flow is PRESET. It converts the input signal's amplitude. The rotary switch selects one of seven commonly needed conversion ratios: *.1, *.2, *.5, *1, *2 *5 and *10.
After that comes ATTEN, a signal attenuator. In it's maximal counterclockwise position it mutes the signal, totally clockwise the signal remains "unity" and is not altered.
Finally there's DC BIAS, creating an offset voltage, from -9V to +9V.
Two LEDs visualize clipping. The processed signal is available at two positive and one inverted output. The positive signal is normalized to the voltmeter.
Speaking of which: the voltmeter has a bright, high-contrast display and two button selectable modes: a virtual analog needle or a numeric value with floating point.
Instead of the processed signal you can feed the voltmeter directly with another signal at the VM input - in this case this direct signal is available for further use at the upper +OUT socket which now acts as a Thru. If no cable is plugged to the VM input it will carry the positive processed signal again.
The stabilizing function reduces the display's update rate - this is very important with really slow CVs in order to make the display work correctly.
The display can be turned off with the I/O button if not needed. This saves the display and reduces the module's current draw. The RST button is used to reset the voltmeter's software in case it shall malfunction.
