Frequently Asked Questions

What is the difference between Lux and Footcandle measurements?
Lux (lx) is the metric unit of illuminance (lumens per square meter), while footcandle (Fc) is the imperial equivalent (lumens per square foot). The DT86 measures both units, with 1 footcandle approximately equaling 10.764 lux.
Does the DT86 include a data-holding feature?
Yes, the instrument includes a Maximum Hold function that captures and displays the highest illuminance reading, useful for documenting peak lighting conditions.
What type of battery does this meter require?
The DT86 requires a single 9V alkaline battery. The auto power-off feature helps maximize battery lifespan between replacements.
Can this meter measure both indoor and outdoor lighting?
Yes, the DT86's wide measurement range (0 to 40,000 Lux/Fc) makes it suitable for assessing illuminance levels in both indoor and outdoor environments.
How often does the meter take readings?
The sampling rate is 1.5 readings per second, providing real-time illuminance data updates during measurement.
