The unit has two sets of outputs on the back panel — one to attach a DVM or recorder, with ±3 V or ±1 mA full scale, using an Amphenol 80-PC2F connector | The unit has two sets of outputs on the back panel — one to attach a DVM or recorder, with ±3 V or ±1 mA full scale, using an [[Amphenol 80 series connectors|Amphenol 80-PC2F connector]], the other output (marked "×1") tracks the input voltage (in "Normal" mode only, s.b.). It is therefore possible to use the 610C as an amplifier, with a bandwidth of 40 kHz at ×1 down to 100 Hz at maximum amplification. | ||
The input connector is a [[UHF connector|PL-259 ("UHF") socket]]. Newer electrometers use triaxial input connectors, with the inner shield (guard) driven by an amplifier to be at the same potential as the input, in order to minimize leakage currents. It is possible to use a guarded input connection on the 610C through an adapter, although the guard potential is only available on the back of the instrument, at the "× 1" output. (The terminal labelled "guard" is at input ground potential.) | The input connector is a [[UHF connector|PL-259 ("UHF") socket]].
