By default, the control window opens with the Dual Picostat in Standby
mode, that is, with the electrodes isolated so that no current will flow
through your sample. To connect to the electrodes you must select Real
Cell mode.
You will need to adjust the gain range to 200 nA to accommodate your
signal amplitude, and to select the 10 Hz low-pass filter (and/or Mains
Filter) to minimise high frequency noise on the signal — especially if
you are working outside a Faraday cage.
You can now adjust the applied potential with the slider bar, or by
entering the exact potential with text entry. The resulting current signal
should obey Ohm’s law:
I = E/R
so that with a 10 Mohm test resistor, R, in place, an applied potential,
E, of 1 V should produce a current, I, of 100 nA, while other potential
settings should produce corresponding currents.
