information about the pin mapping of these adaptors.

All NZA series adaptors should be plugged into nanoZ so that the 3-pin header

on the adaptor is closest to the USB port end of the nanoZ. If using the NZA-

DIP16 adaptor mapping defined in ʻelectrodes.iniʼ, be sure to plug the adaptor

into the ʻlowerʼ Samtec socket closest to the bottom edge of the nanoZ.

In the current version of the nanoZ, only R1 is connected to the internal circuitry.

R2 and R3 are reserved for future expansion. If you wish to make your own

reference electrode cable, be sure that it connects to R1 (see Appendix C).

The nanoZ is supplied with a 32 channel calibration adaptor (NZ-CAL) that

comprises a bank of resistors and capacitors of various impedances (Appendix

D). Use this adaptor to check the accuracy of your nanoZ across the specified

working range (Appendix B).

The nanoZ does not require routine calibrations, however future firmware and

software upgrades may necessitate a device re-calibration, for example, to

extend the nanoZʼs functionality or working range. The NZ-CAL adaptor may also

be used to test whether 3

party electrode adaptors or tether cables introduce

errors in the impedance measurements.

The calibration adaptor should be orientated with the ʻNZ-CALʼ

text closest to the USB port, and the software should be set to No

Adapter / Probe not selected.

The nanoZ is capable of providing very accurate measurements across a wide

range of test frequencies and impedances (Appendix B). Nonetheless, care

should be taken to protect the test setup from electromagnetic interference (EMI)

such as 50/60Hz power line interference. The nanoZ is susceptible to EMI
