Preliminary Specifications:
The New Spectra Professional V Light Meter is an advanced device designed to measure light intensity with high accuracy. The hardware includes a powerful microprocessor, a 2.8-inch color TFT LCD, and signal conditioning circuitry for greater sensitivity and accuracy. The display is equipped with a touch screen and controlled backlighting, making it easy to use and read in any lighting conditions. The battery power management system ensures that the meter can be used for extended periods without replacing or needing to recharge.
The firmware for the microprocessor was developed using a popular development framework and a graphics library for managing the touch display. This firmware handles hardware initialization and control, auto-ranging, display, storage, energy saving, settings, calibration, and diagnostics. It is designed to provide accurate and reliable light measurement readings.
The Spectra Professional V Light Meter architecture is based on its predecessor the Spectra Professional IV-A Light Meter technology, which was awarded multiple awards including Technical “OSCAR” and Engineering “EMMY” and has been the Standard in the motion picture industry for over 30 years and over 20 thousand meters are used worldwide since its introduction.
It features a trans-impedance and multiple-range linear circuit, making it the widest dynamic range circuit available in a handheld meter design. The meter is designed to measure from one hundred million to one or 0.01 to 1,076,400 lux, making it suitable for a wide range of applications.
The Spectra Cine Professional V Light Meter measures incident and *reflected light with the 1-degree spot attachment, making it suitable for use in a variety of settings. It measures f-stop from 0.35 to f-stop 90.9 (f-stop 128) in 1/10-stop increments on the digital scale and from f 0.7 to f 45 in 1/3-stop increments on the analog bar graph. This makes it easy to measure light intensity accurately and reliably.
The meter can store up to ten different measurements. This memory feature can recall RCL and delete memorized readings, including film speed, exposure time, f/stop, foot-candles, and lux combinations in mem0 to mem9 addresses. The stored readings can be recalled with a simple press of the RCL switch, and a long press on the STR switch which deletes the stored reading.
The Spectra Professional V Light Meter also includes a touch menu on the Cine screen, which takes you to a Menu screen where you can select Edit Filter Factor, Camera Shutter Angle, Hardware Settings, and Product Information. This feature makes it easy to customize the meter to suit your specific needs.
Flexible power supply:
The device can be powered using 3 x AA 1.5 volts long-lasting lithium batteries or 3 x AA Nicad rechargeable batteries or Spectra Power Bank which can be purchased separately. It can be connected via the meter’s USB C port and should be able to continuously operate the meter for several days. To extend the life of the batteries the backlight display should be set at 50% brightness for optimum brightness and power conservation. The backlight display brightness can be adjusted from 5% to 100%.
In summary, the New Spectra Professional V Light Meter is an advanced device designed to measure light measurement accurately and reliably. It features a range of advanced technologies and functions that make it suitable for use in a wide range of applications.
Accessories Supplied:
The Spectra meter comes with Photosphere (for ambient light), Photo Disc (for key or directional light), Meter Carrying case, Neck-strap, 3 x AA batteries, Quick reference chart (brief instructional manual), and a warranty registration form to be filed online at www.myspectra.com
