In reflected-light mode, the meter will see roughly what the camera sees (it has a 25-degree acceptance angle, unless you have the 5-degree "spot" accessory), and should give you a similar reading.
However, is the subject is unusually light or dark, or likely to fool the camera's meter, the handheld meter, in incident mode, will give you a more accurate reading. It's also ideal for studio use, with hot lights or strobes, since it lets you determine your lighting ratios, as well as the overall brightness. Most studio shooters would say an incident ambient/flash meter is indispensable. I've used the 328 Digilite F for two or three years, and find it handy, compact, and accurate. In case you didn't get the instructions with it, you check the battery condition by holding down the ISO button when you switch on the meter. Hope this is helpful. Pat White
