The Powerlab Self-Test - ADInstruments PowerLab 30 Series Owner's Manual

The PowerLab Self-test

Now that you are familiar with some of the features of your PowerLab, you
should check that it is working properly before you connect it to your
computer.
The PowerLab performs a diagnostic self-test each time it is switched on,
whether or not it is connected to a computer. To test that your PowerLab is
functioning properly when you turn it on, follow the instructions below, and
watch the indicators.
1. Connect the PowerLab to a power outlet using the power cable that came
with your unit. Turn on the power at the wall.
2. Turn on the power switch located on the rear of the unit.
All three labeled indicators on the front panel should turn on, at least briefly,
while the PowerLab is starting up. The Power indicator on the front panel
should glow blue while the PowerLab is on (see page 15). If the internal
diagnostic check finds no problems, the Status indicator will flash yellow and
then stay green. (The Trigger indicator should flash yellow, when the trigger
operates.)
If the indicators perform as described above, then your PowerLab has
successfully performed its internal self-test, and it can be safely connected to
your computer. If your PowerLab does not successfully complete its self-test,
something is wrong.
If the Power indicator does not glow blue when the power switch is turned on,
then there is a problem with the power source, power cable or PowerLab itself.
Check the connections and cables.
If an error is detected during the self-test, the Status indicator will flash red.
Flashing lights are used when the problem is one that prevents the PowerLab
communicating with the computer, and so cannot be shown in the software.
Four red flashes separated by a yellow flash mean there is a low-level software
or hardware fault. Red flashes mean there is a hardware fault. (See Table 1–1
for details.)
Turn everything off, and then after at least five seconds turn the PowerLab
back on again. This should clear a temporary problem. If it still continues to
flash red, then the PowerLab may need repair.
If the PowerLab does not seem to be getting power, or the Status indicator
flashes red even after restarting, refer to the ADInstruments tech support
