Thermo-Anemometer with Wind Speed, Wind Chill and Temperature
Introduction
Congratulations on your purchase of Triplett AM200 Mini Thermo-Anemometer. This professional meter, with proper care, will provide years of safe reliable service.
Meter Description
- Vane impeller
- Precision thermistor
- LCD display
- POWER and HOLD key
- UNITS and MODE key
- Battery compartment (on rear)
- Swivel handle and storage case
- Lanyard holder
- Impeller set screw (on rear of meter)
Operation
Select the desired units for air velocity and temperature by momentarily pressing the UNITS/MODE key from a powered down condition. The LCD will show temperature units (°C or °F) and Air Velocity units. Press the UNITS/MODE key repeatedly until the desired units are displaying. When finished, press the ON/OFF/HOLD key momentarily to restart the meter with the desired units.
Power the meter by pressing the ON/OFF/HOLD key momentarily. The Dual Display will illuminate. The top (larger) display indicates air speed and the lower display indicates temperature.
Position the meter so that the measured airflow enters the meter vane from the rear of the meter (opposite side from the front panel logo, part number, etc.).
Activate Data Hold (to freeze the most recent display), by pressing and holding the ON/OFF/HOLD key while taking measurements. To return to normal operation, release the key and restart the meter.
Max operation: After a measurement session, press and hold the UNITS / MODE key until the MAX icon appears on the lower left-hand side of the LCD. Both the Air Velocity and Temperature indication will represent the highest readings measured since the meter was last powered.
Average mode operation: Normally the meter averages readings every 2 seconds. To select 5, 10 or 13 second averaging, first press and hold the UNITS/MODE key until the MAX icon appears. Next, press the key again momentarily and the AVG icon will appear. The 13 second average mode is selected. Now press the key again and the number 5 will appear. Leave it there if an average of 5 seconds is desired. Press the key once more for a 10 second average mode. To return to normal operation press the UNITS/MODE key repeatedly until all lower left-hand icons disappear.
Wind chill indicator: Press and hold the UNITS/MODE key until the MAX icon appears. Press the key repeatedly until the WCI icon appears. The temperature display will now factor in the wind chill. To return to normal operation, press the UNITS/MODE key again and the WCI icon will disappear.
AUTO POWER OFF: After approx. 20 mins, if meter keys are not touched, the meter automatically shuts down to preserve battery life.

Maintenance
Battery Replacement
The AM200 has a low battery indicator (battery symbol). Important: Turn the meter off before opening the battery compartment. Using a coin, turn the battery compartment cover CLOCKWISE to remove it. Once opened, observe the position of the battery, placing the new one in the same position. Secure the battery compartment cover and dispose of the lithium battery in accordance with local, state, or national disposal codes.
All EU users are legally bound by the Battery Ordinance to return all used
batteries to community collection points or wherever batteries / accumulators
are sold.
Disposal in household trash or refuse is prohibited.
Disposal: Follow the valid legal stipulations in respect of the disposal
of the device at the end of its lifecycle
Other Battery Safety Reminders
Never dispose of batteries in a fire. Batteries may explode or leak.
Never mix battery types. Always install new batteries of the same type.
Impeller Replacement
Remove the set screw next to the impeller assembly (on the rear of the meter).
Twist the impeller assembly counter-clockwise to the OPEN position and remove
it.
Install impeller by inserting & twisting the new impeller assembly clockwise
Tighten the set screw.
CFM Measurements
Measure the area of the duct using the diagrams below for rectangular and circular ducts (If the duct measurements are made in inches, divide the inches by 144 to get the area in square feet). Plug the area value (in square feet) in the cubic equations below. Note that the air velocity must be plugged into the cubic equations also.
*A = wh A = πr²**
CFM (ft³/min) = Air Velocity (ft/min) x Area (ft²)
CMM (m³/min) = Air Velocity (m/sec) x Area (m²) x 60
