The clamp features Bluetooth technology to connect compatible mobile devices for remote viewing and sharing, and METERLiNK technology to wirelessly embed electrical readings into radiometric infrared images on compatible FLIR thermal cameras (cameras not included).

• True RMS voltage and current plus non-contact voltage detector
• Remote viewing on smartphones and tablets via Bluetooth
• METERLiNK to wirelessly embed readings into thermal images on compatible FLIR cameras
• Advanced power efficiency and harmonics measurements for system level performance analysis
• Inrush mode captures fast AC current spikes during appliance start-up
• Phase rotation testing ensures the motor and power source are aligned
• Large, easy-to-read digits, backlit display and analog bargraph
• Powerful LED lamps to serve as a primary work light
• 6.5' drop test

Q: 1. Will this meter fire Godex strobes wirelessly?

A: This will only trigger a Godox light wirelessly if you have a trigger plugged into the pc port on the meter.

Q: 2. Can this meter be used for video recording? Is the answer "Yes, but it's better to pay a little more for a better meter."

A: It simply depends on your needs and your budget. According to Sekonic's website, the Sekonic L-208 Twin Mate can be used for cine usage needs. You can get more features with a higher-end model such as the Sekonic L-308X-U Flashmate Light Meter, B&H # SEL308XU, which has dedicated Cine and HD Cine modes and allows you to choose video frame rates between 8-128 fps with one-tenth of a stop accuracy. However, if you are using standard shutter speeds from 1/8000 to 30 Seconds, plus 1/800, 1/400, 1/200, 1/100, 1/50, 1/25, 1/10, 1/5, then the Sekonic L-208 Twin Mate would work for videography usage needs.

Q: 3. "Can it toggle back and forth between a shutter speed/aperture reading (let’s say, f/8 @ 1/60) and then to its EV equivalent (say, EV 12) (and then back to f/8 @ 1/60) or does changing the mode erase the existing reading?"

A: Yes you can

Q: 4. Can I set this meter that I want to use a shutter speed of 200th of a second? Or will it only go to the straight numbers like 125 and 250?

A: Yes, in custom settings.

Q: 5. Does this light meter have any cinema / video related functionality?

A: Yes it has Photo, Cine, and HD Cine Metering Modes

Q: 6. For measuring contrast of light, what is the precision of the result, can it display in 0.1 EV values, or rounded numbers like 1/3 or 1/2 EV?

A: Default setting is the .1 values, but you can do a custom function to measure in 1/3 or 1/2.

Q: 7. This meter is used for both incident and reflected light metering purposes. I know that all handheld light meters measure incident light, but I don't understand why this meter is needed for reflected light measurements. The camera's built-in light meter is much quicker and easier to use for a reflected reading. What is the purpose of taking a reflected reading from a handheld light meter?

A: Light meters were designed long before there were meters in any cameras; since some people still like to use a hand-held meter, there was no reason to remove a capability that was already built in.

Q: 8. Can it be put on a stand if I'm using an uncorded flash without an assistant to hold the meter?

A: Unfortunately this does not have a 1/4-20 on the unit so it can not be screwed onto a stand.

Q: 9. Can you set the aperture of your camera and have it give you the shutter speed? With my old meter I can only set shutter and not f stop.

A: Yes you can set the aperture

Q: 10. What is the highest ISO?

A: The highest ISO reading is 8000.
