Performing Impedance Checks
Check the impedance between the stimulator and the electrodes by performing an impedance check.
To perform an impedance check:
1. Tap the Impedance tab on the Programming screen.
2.
Tap an electrode or the can (stimulator housing) on the Programming screen, then tap to assign the electrode or
can as the sink (the direction of the current ow). If you do not select another electrode, the default sink is the can.
3. Optionally, tap the Impedance bar and select the impedance amplitude (the amplitude at which the stimulator
performs the impedance check) by tapping low or high in the Estimated Impedance popup. e default setting is low.
Low is 0.2 mA and high is 0.5 mA. When performing an impedance check, start with the low amplitude setting to
avoid patient discomfort.
4. Close the popup.
5. Tap All to perform an impedance check on all electrodes or tap the Active button to perform an impedance check on
only the active programmed electrodes.
6. Optionally, use the Estimated Impedance slider in the popup to adjust the estimated impedance level for stimulation.
Contact Nuvectra Customer Service for more information about this advanced feature.
Over time, the impedance at the stimulation site may increase and the slider may need adjusting. You can determine
an estimated impedance by performing an impedance check and reviewing the reported values for active contacts.
Indicate the estimated impedance using the Estimated Impedance slider. e default value is the lowest impedance
expected for safety of the patient and prolonged battery charge of the pulse generator. If impedance increases without
adjusting the Estimated Impedance slider, the patient may experience a lessening of strength in stimulation.
