page 4 IVPC Installation & Quick-Start DS-100C Operating Manual
With the DS-Tracer DISCONNECT switch still OFF, attach the test leads to your
PV module. By making connections with the PV system disconnect switch off,
the chance of electric shock is avoided. After connecting the test leads, close the
PV system switch. At this point, PV voltage should be present at the DS-Tracer.
Turn the DS-Tracer DISCONNECT switch to ON. Note: For normal operation,
the DS-Tracer DISCONNECT switch should always be the last switch closed and
the first switch opened.
Starting IVPC
The following description assumes the use of IVPC 2.X. IVPC opens to the Data
Grid window shown in Figure 1. IVPC Data Grid window.. The Data Grid is a
spread sheet that lists all of the I-V curve data files stored in the current
directory. When starting IVPC for the first time the Data Grid may be empty if no
I-V curves have been taken.
Figure 1. IVPC Data Grid window.
The Data Grid can be thought of as a detailed directory of the I-V curves.
However, in addition to file names, you can display other curve data such as
peak-power or module ID. Refer to the IVPC Reference Manual for directions for
changing the data displayed. Use the Data Grid to locate and display I-V curves
that were taken previously and stored.
