Restart your PC thenVoltaMaster 4.4.9.2 Curve points are missing – zero current points are foundWhen running the experiment, a current range switching has occurred in the sametime as a measurement data acquisition. In this case, VoltaMaster 4 has replacedthe measured current by zero (in Pot. Universal DP, Pot. Recurrent DP or Pot.Square WV) or has skipped to the next acquisition point (for all other potentiostaticmethods). The curve shows an artefact (point set to i=0) or there is one pointmissing. The artefact can be deleted from the curve afterwards. Nevertheless, ifyou want to perform a differential extraction on a curve having one artefact, do itbefore suppressing the point as the extraction tool requires all the points of thecurve to work correctly.To delete a point, consult the Help file, keyword index:Deleting points from a curve.4.9.3 Some methods are missing in the sequence edition listYou have selected a wrong instrument type in the “Instrument setup” dialoguebox. Select “Settings – Instrument setup” or “Edit - Instrument setup” then select a“Potentiostat” (VoltaLab PGP201, PGZ100, PGZ301, PGZ402, PST006 or PST050)corresponding to the one you are using (potentiostat connected to your PC).Example:If you intend to run a pulse technique (Pot. or Gal. Universal DP, Pot. or Gal.Recurrent DP or Pot. or Gal. Square WV), you must select “Potentiostat = VoltaLabPGZ402” and connect a PGZ402 potentiostat to your PC.98VoltaMaster 4 - Version 7.0xSection 4, Chapter 9: Troubleshooting list
