This command opens a Windows File dialog box. The current curve(s) involved in the selected ASCII-file(s) will be merged to the existing ones when setting the Option: Import Data in the Property-Window correspondingly. Otherwise, all simulation objects will be removed from the active document before importing the selected file(s).
Full use-formatthe full use-format contains the current curve and a full description of the experimental parameters. The latter must be written to the file in exactly the same form as on the Property Page: Simulation Parameters: DigiElch_FT_Header experimental parameters: key_word_1: Value_1 key_word_2: Value_2 . . filter settings: fmin_1: fmin_value_1 , fmax_1: fmax_value_1 fmin_2: fmin_value_2 , fmax_2: fmax_value_2 fmin_3: fmin_value_3 , fmax_3: fmax_value_3 fmin_4: fmin_value_4 , fmax_4: fmax_value_4 fmin_5: fmin_value_5 , fmax_5: fmax_value_5 fmin_6: fmin_value_6 , fmax_6: fmax_value_6 fmin_7: fmin_value_7 , fmax_7: fmax_value_7 . .

Minimum use-formatData measured with third-party electrochemical instruments are usually exported in file formats which differ from instrument to instrument. The minimum use-format enables the user to produce an importable use-file with a minimum of effort provided the experimental data files satisfy the following prerequisites: •The experimental current curve is available in ASCII-format. •The current points refer to equal time steps. Only small deviations from equally spaced time intervals do not matter.
The minimum use-format is as follows: DigiElch_SW_Header number of E (V), I1 (A) | I2 (A) couples : N E1_1 , I1_1 E2_1 , I2_1 E1_2 , I1_2 E2_2 , I2_2 . . E1_N , I1_N E2_N , I2_N
•E1_i and I1_i •E2_i and I2_i
Files in minimum use-format do not contain any information about experimental parameters such as scan rate, electrode surface, electrode geometry or species concentrations. It is therefore not possible for the fitting procedure to recognize to which parameter combination a particular experimental curve refers. Consequently, such files are useful only for viewing experimental current curves. Apply the Edit/Modify command to add the experimental parameters to each file.
