The nanoZ application has five separate modes of operation for performing a

variety of different tasks. These modes can be selected by clicking a button on

the left pane of nanoZ application or via the Mode menu on the main menu.

The following instructions assume that a suitable electrode adaptor and probe

configuration have been chosen, and the electrode sites of interest have been

selected in the Probe window.

interface may vary depending on the version of Windows you are using.

This mode provides manual control of the nanoZʼs site selection, impedance

testing, and DC constant current electroplating functions.

Selecting Impedance (A) will continuously measure the impedance of the

currently selected channel (B) at the specified Test freq (C). The impedance (in

Mohms), and phase angle (in degrees) will be displayed on the DMM. If the test

signal is saturated (e.g. high levels of 50/60Hz noise) the ʻTest signal clippedʼ

warning message will be displayed and the DMM will show the last valid

impedance measurement.

If One shot is checked, a single impedance measurement will be made. To stop

continuous impedance measurements, select Off (A).

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
