• Serial or USB cable to connect your computer to the DS-Tracer.
IVPC Installation
IVPC is written for use with Windows® 98/2000/XP which must be running to
operate IVPC. To install IVPC, insert the IVPC CD-ROM in your computer. Open
the IVPC CD-ROM and run the “setup.exe” program by double click with the
mouse.
The setup program will prompt you for information on where you want to install
IVPC. If you are unsure, use the defaults which create an IVPC sub-directory off
of the root directory on drive C:. IVPC Setup automatically installs the necessary
files in the IVPC directory and makes additions to your Windows system
directory.
Precautions
There are several precautions to observe before using the DS-Tracer and IVPC
to take I-V curves.
• The DS-Tracer battery should be fully charged. The DS-100C has a universal
power supply that works with AC line voltages from 85 V
ac
to 264 V
ac
50/60 Hz.
• The DS-Tracer DISCONNECT switch should be in the OFF position and the DS-
Tracer power should be turned on when making or breaking connections to a PV
system or when changing the voltage range switch.
• The DS-Tracer should be connected to the PV array through a PV system
disconnect switch capable of interrupting the short-circuit current of the array at
peak-power voltage. This ensures that you can disconnect the DS-Tracer if a
problem occurs. Refer to the DISCONNECT switch discussion in section 2.0
Panel Layout for details.
NOTE: The DS-Tracer DISCONNECT switch is not rated to interrupt high
voltage systems producing more than five amps.
• Do not connect the DS-Tracer to anything other than an open-circuited PV
system. Be sure the PV array is electrically isolated from power conditioning
equipment such as charge controllers or inverters.
