Little brother of the tester above. Same great features but tests a smaller array of batteries.Tests: 1.2V NiMH, NiCd rechargeable (AAA, AA, C, D), 1.5V alkaline (AAA, AA, C, D, N), 3V photo lithium (CR123, CR2, CRV3), 9V alkaline, zinc-carbon.
The digital Spectra professional IV meter was introduced in May 1992 at the American Society Of Cinematographers Club House. It measures Foot-candles, Lux and F/stops - the key unit of measurement used in Cinematography and Television applications.
The Spectra Professional IV-A measures incident and reflected light directly in -stops, footcandles or lux and instantly calculates the f/stop difference, contrast ratio and average of your particular lighting situation. The multiple channel memory enables you to recall the stored measurement, current measurement, f/stop difference, contrast ratio and average. The meter covers a sensitivity range of almost one-million to one.
This makes the hand-held incident meter a kind of insurance policy that eliminates second-guessing and gambling with exposure control, especially under the more difficult and extraordinary light conditions that are apt to confront the serious photographer.
The Spectra Professional IV-A has a Digital f-stop measuring range that extends from f/0.24 to f/128 in 1/10-stop increments and the Analog Bargraph range from f/0.7 to f/45 in 1/3-stop increments. Both are displayed simultaneously on a backlit liquid crystal display, along with film-speed, frames per second for cine use or exposure time for still photography.
Checks for electrical current without breaking the connection.
A "volt tick" is a handy tool that belongs in every electrician's toolpouch or shirtpocket. Got a bad lamp? Check to see if it's getting current quickly and easily by just TOUCHING THE CABLE with the tip of the tester. It tests for voltage right through the insulation!
The Santronics AC Sensor is powered by two AAA batteries. To replace the batteries, just unscrew the white cap. The The Santronics is always ready for use. It never has to be turned on or off. If there's current passing though the cable the entire white tip will glow a steady red.
FAQ: John, I'm confused. I can't decide which "volt tick" to buy. Can you offer any help?
Sure, it's really a matter of balancing personal taste with the situations you think you'll be using it in most. The Greenlee with its audible ringer is a good choice especially while focusing. There are always situations when you need to check a cable, but can't see the tester because you're blocked by the light. The ringer solves that situation. On the other hand, if you're working shows that are inherently quiet (soaps, theatre) the silent Santronics allows you to check cables without worrying about the noise of a ringer. I carry both the Greenlee and Santronics in my tool bag because I never know what situation I might be in.

The Greenlee is powered by two button batteries. To replace the batteries, just pull off the black cap. Turn the Greenlee on by sliding the plastic protector up and then pressing on the metal shirt clip. If there's current passing though the cable you'll get an audible ring AND a flashing red light.
