RECALL
Introduction
Congratulations on your purchase of the Extech AN200 CFM/CMM Thermo Anemometer with
InfraRed Thermometer. This instrument measures Air Velocity, Air Flow (volume), Air
Temperature (with probe) and Surface Temperature (with the InfraRed function). The large, easyto-read backlit LCD includes primary and secondary displays plus numerous status indicators.
The InfraRed feature includes a laser pointer for convenient targeting. In addition, the meter can
store 16 area setting dimension for easy recall. This meter is shipped fully tested and calibrated
and with proper use will provide years of reliable service.
Safety
Use extreme caution when the laser pointer beam is on
Do not point the beam toward anyone's eye or allow the beam to strike
the eye from a reflective surface
Do not use the laser near explosive gases or in other potentially
explosive areas
CAUTIONS
Improper use of this meter can cause damage, shock, injury or death. Read and understand
this user manual before operating the meter.
Inspect the condition of the probe and the meter itself for any damage before operating the
meter. Repair or replace any damage before use.
If the equipment is used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
This device is not a toy and must not reach children’s hands. It contains hazardous objects as
well as small parts that the children could swallow. In case a child swallows any of them,
please contact a physician immediately
Do not leave batteries and packing material lying around unattended; they can be dangerous
for children if they use them as toys
In case the device is going to be unused for an extended period of time, remove the batteries
to prevent them from draining
Expired or damaged batteries can cause cauterization on contact with the skin. Always,
therefore, use suitable hand gloves in such cases
See that the batteries are not short-circuited. Do not throw batteries into the fire.
Do not directly view or direct the laser pointer at an eye. Low power visible lasers do not
normally present a hazard, but may present some potential for hazard if viewed directly for
extended periods of time
