Older versions display the comparison (offset) voltage through a mechanical dial, newer versions through an LED panel meter. in addition, this voltage is brought out through a front panel connector so it can be measured externally.

Specifications

Deflection factor 1 mV/Div – 5 V/Div (1–2–5 sequence)
Common Mode range: at least +10V / -10V from 1 mV/Div to 50 mV/Div;
