Setting up a CR Tester
CR models distributed before September of 2010 have a serial port (if your PC does not have a
serial port, you will need to use the Keyspan USB Serial Adapter provided by Cirris). CR testers
distributed after September 2010 have a USB port.
Step 1
Look at the back right corner of your Demo
CR tester and determine if the tester has a
Serial Port or USB port as shown.
Step 2
If you have a serial port,
see below.
If you have a USB port,
skip to the top of
next page.
Serial Port:
a. Connect the serial cable to the tester.
If your computer has a serial port
,
connect the other end of the serial
cable directly to your computer.
If your computer does not have a
serial port,
insert the Keyspan CD into
your PC and install the drivers.
Connect the USB and Serial cables
into the USB Serial Adapter. Then plug
the loose end of the USB cable into
your PC.
b. Plug the wrist strap into the probe
socket.
c. Connect the power cord (notch side
up) between the tester and the same
grounded outlet that your computer is
plugged into.
