Power-Up Test; Usb Cables - Gamry Reference 600+ Operator's Manual

The external power supply provided with the Reference 600+ is rated for operation from 100 to 240 V
AC, at frequencies from 47 to 63 Hz. It should therefore be useable worldwide.
The Reference 600+ external power supply is normally supplied with a line cord suitable for use in the
United States. In other countries, you may have to replace the line cord with one suitable for your type of
mains (electrical outlet). You must always use a line cord with a CEE 22 Standard V (IEC 320 C13) female
connector on the end of the cable leading to the unit. This is the same connector used on the US standard
line cord supplied with your Reference 600+. See Chapter 1 for specific safety information regarding
power-cord selection.
The DC output cord from the external power supply plugs into the Power In jack on the rear panel of the
Reference 600+ (see Figure 4-2).

Power-up Test

Before you make any other connections to your Reference 600+,
check that the Reference 600+ is at least nominally functional.
After connecting DC power to the Reference 600+, turn on the
Power switch on the rear panel of the Reference 600+ (see Figure
4-2).
Watch the Power LED on the front panel as the Reference 600+
powers up. This LED should go on for a second or so, flash three
times, then remain on.
The status of the other LED indicators is not important at this time.
Each flash of the Power LED upon startup corresponds to
successful conclusion of one portion of the power-up self-test.
Caution:
on, then turns off and stays off, the Reference
600+ is not working properly! Contact Gamry
Instruments or your local Gamry Instruments
representative as soon as possible if this power-up
test fails.

USB Cables

The Reference 600+ connects to the computer using a standard High Speed USB A/B cable. A suitable
cable was shipped with your Reference 3000. If this cable is lost, you can get a replacement at almost any
computer retailer. The replacement cable should be rated for USB 2.0 high-speed USB operation.
An A/B USB cable has different connectors on each end. The end with a wider, rectangular-shaped
connector plugs into a USB port on your computer (or a similar port on a USB hub). The end with a nearly-
square connector plugs into the USB port on the Reference 600+ (see Figure 4-2).
The USB connection can be "hot-plugged". This means both the computer and the Reference 600+ can
be powered up before the USB cable is plugged in. Unlike many other instrument-to-system connections,
you need not power down the system before plugging in the USB.
