Light meter calibration procedure.

We state our traceability to our in house 0 5 nist standard as 3. This is to allow for the transfer from the nist standard to our secondary standards and then the transfer to the probe being calibrated. Our light meter calibration processes ensure that your instruments meets engineering machining parts design quality control and inspection requirements. What actually happens in our 365nm standard for example is that the.

Multiple test points are taken across the full range of the device at intervals based on type of equipment. Switch the camera to manual mode and deactivate all functions that affect the exposure. If you are calibrating an incident meter use a flat disk hold the meter in front of the gray card and pointed at the camera. The light meter then gathers the reflected or incident light levels as per the type used.

Professional light intensity lux meter that measures illumination levels in lux. Light meter calibration light meters are utilized in a variety of industries and applications including photography cinematography osha compliance security quality assurance photosensitive materials regulatory requirements process controls and clean room standards. You ll be confident knowing that your instruments will provide accurate measurements. I know that many of you don t use a meter but they can be very useful in verifying the speed of the chip in the camera you might be shooting with.

As light meter calibration specialists all g r labs light meter calibration services are traceable to the national bureau of standards nist with a 0 5 in house standard for radiometric calibrations and an in house 1 0 traceability for photometric calibrations. If you need to maintain the accuracy of your instruments then you need light meter calibration services from acs calibration. Your exposure should be at a 2 8 or very close to it. Set the same iso value e g.

To calibrate your meter we recommend the following method. This data is then stored for easy 24 7 access within gagesuite our cloud based calibration management system. An incident meter should be pointed toward the camera. Iso 100 in the external exposure meter and the camera and make sure that all correction values are at 0.
