Selecting Current (A) mode will apply a DC constant current to the currently
selected channel (B) at the level indicated adjacent to the Current level slider
(C). The current can be adjusted from -12uA (electrode negative) to +12uA
(electrode positive) in ~1nA steps by moving the position of the slider or typing
the desired current into the edit box. The voltage across the electrode site will be
displayed on the Meter. The Meter has limited measurement resolution (39mV)
and should be considered approximate, however the calibrated current reading
shown in the edit box is accurate to within ±5nA or 5% (whichever is greater).
The Meter also indicates if the voltage is out of compliance, that is, if the voltage
needed to achieve the desired current is greater than the nanoZ can generate.
To stop applying the current, select Off.
The nanoZʼs electroplating circuit has a native resolution of ~100nA. To enable smaller
currents and ensure the specified electroplating accuracy, devices shipped prior to April
2012 need to be recalibrated (see Appendix E).
