Light, Sound and Weather Meters

FAQ – Light Meter eL200K

The ennoLogic light meter is NOT for photography. It does NOT provide a way for you to determine the proper exposure for a photo. Its purpose is to show you light intensity in lux or foot candles at any given location.
The light meter turns itself off after 5 minutes of inactivity. You can disable this feature by holding the “Units” button down while turning the unit on. You will see the Power Symbol appear on the LCD, indicating that the auto-power-off feature is disabled.
The “DC” and “AC” Output ports provide an analog signal that can be used to record the measured light level signal with a data logger (200,000 lux = 3300mV). A short adapter cable that ends in two bare wires is included for that purpose.
This port provides an alternate way to power the instrument. To use it you will need a USB A-Male to Mini-B cable to power the unit from a USB power adapter. The cable and power adapter are not included with the light meter.

FAQ – Decibel Meter eS528L

There is an error in version 1.1 of the user manual. The pinout diagram for the 3.5mm plug is incorrect. Version 1.2 of the manual available for download on our website shows the correct pinout. Sorry for the confusion!

Also, please make sure to push the plug in all the way, otherwise it is not making proper contact with the output port connectors.

FAQ – Anemometer eA980R

Yes, the anemometer can be calibrated for all parameters. The instructions for that are included in the user manual. Some parameters, like barometric pressure, are pretty easy to calibrate, you just use a reliable online weather service that reports atmospheric pressure for your location. Temperature calibration will require you to have an accurate thermometer. Calibrating wind speed is more complicated, most of us don’t have access to a wind tunnel. Unless you have the equipment needed to calibrate wind speed, we recommend not changing the factory calibration for wind speed on your anemometer.
The eA980R anemometer does not measure absolute altitude, like a GPS device, but measures pressure altitude instead. Pressure altitude is used in aviation planning. It is a relative altitude measurement based on barometric pressure. Pressure altitude is defined as ‘the altitude above or below a theoretical 29.92 inHg standard datum plane.’ For every 1000 feet you go up in altitude there is a decrease of about 1 inHg. The barometer’s reading at a certain altitude compared to the 29.92 inHg standard pressure can be used to calculate pressure altitude: Pressure Altitude = (29.92 – Current Pressure) x 1,000 + Field Elevation, where field elevation is the elevation of the airport location.

The temperature sensor is located behind the little hole on the left, just below the impeller. You can decrease the response time by increasing the air flow through this hole, for instance by holding the anemometer into the wind or air flow, or by moving the anemometer back and forth. When air is continuously moving through the anemometer, the response time is about 30 seconds. Without air flow, the response is much slower (several minutes) because the temperature sensor is located inside the unit.

With the anemometer turned on, press and hold the “Set” button for about 2 seconds, until the backlight comes on.
The only batteries that will work for your anemometer are LIR2032 lithium batteries. Do NOT use CR2032 batteries (which are not lithium!) in the eA980R or it will NOT work. The LIR2032 provides a higher voltage than the CR2032. You can recharge LIR2032 batteries with a suitable charger that you can buy online.
