How Do You Gauge AV Performance?
1/31/2006
By Will Craig
Light level meters are useful for tweaking lighting in existing rooms, and
for measuring whether the amount of light that you requested for your new distance
learning room has actually been provided by your lighting designer or electrical
engineer. When you ask for 50 foot-candles on the instructor's face and you
only get 25, the light meter is critical to getting things fixed right away,
and on someone else's dime. I use an Extech Q527, but there are plenty of models
that are good for general-purpose measurements between $100 and $200.
All of these testing devices can pay for themselves quickly if put to good
use. An annual budget of $500-$1000 for AV test equipment could deploy all of
the types of test gear mentioned in this article within three years. And, through
identifying problems using objective criteria and getting them fixed, you can
spend your time money on more fun pursuits--like those new product demonstrations.
