Chapter 3: Warnings and Precautions
Please make note of the following warnings and precautions. Failure to follow
these guidelines can result in damage to your DataCollector and possibly bodily
harm.
IMPORTANT: The AC adapter that comes with the Zire handheld
will not work with the DataCollector. Use only the 9V DC adapter
with the DataCollector that has the CPO Science name/logo on it.
IMPORTANT: Do not over-tighten the thumbscrew on the
photogates. Over-tightening can flex the body of the photogate
enough that the light emitter and receiver twist out of alignment,
causing the photogate to malfunction.
WARNING: Do not plug any lines from the telephone system in to
the DataCollector’s Analog or Digital ports. Telephone rings (also
present with modems) generate large voltages that can damage or
destroy the DataCollector.
WARNING: Computer data cables have the same (RJ-11) connec-
tors and look like the telephone cords used with photogates, but
are wired differently inside. Using a data cable will ruin the
photogates.
WARNING: When using the DataCollector, be sure not to exceed
the specifications on the voltage, current or other sensor(s) being
used. This can damage the sensor or cause serious injuries.
