Introduction Thank you for selecting the Extech EN510 Environmental Meter. This instrument measures Air Velocity with Air temperature, Air Flow (volume), Light, Relative Humidity % with Air temperature, Dew Point temperature, Web bulb temperature, Type K temperature (external probe), Heat Index temperature, and Wind Chill temperature. The backlit LCD includes primary and secondary displays plus a variety of intuitive status indicators.

Meter Functions Meter Power • • • Three (3) 1.5V ‘AAA’ batteries power the meter. The battery compartment is located on the rear of the meter secured by one flat head screw. Short press the power button to switch the meter ON. The meter will begin displaying readings for the mode selected. Long press the power button to power OFF the meter. Auto Power OFF (APO) In order to conserve battery life, the meter will automatically switch off after approximately 10 minutes of inactivity.
Reversible Backlight LCD The LCD display automatically reverses its presentation orientation depending on measurement mode. This is to match the display orientation with the selected sensor mode (light, air velocity, or environmental measurements such as Wet bulb temperature). The LCD is equipped with backlighting for easier viewing, especially in dimly lit areas. With the meter powered ON, short press the power button to turn ON the backlight. The backlight will power OFF after several seconds.
Air Flow (CFM, CMM) Volume Measurements • Press and hold the M button until ‘AirFl’ appears. • Enter the duct area (in square feet or meters) by short pressing M and long pressing R until ‘m-2’ (m2) or ‘f-2’ (ft2) appears. Short press the power button to increase or H to decrease the area; Long press the power or H button to scroll quickly. See area equations below.
Maintenance Battery Replacement When the low battery icon appears on the display please replace the batteries as described below. 1. Remove power from the meter. 2. Remove the flat head screw that secures the battery compartment at the back of the meter. 3. Open the battery compartment and replace the three (3) 1.5V ‘AAA’ batteries observing correct polarity. Re-assemble the meter before use.
