Light Meter Calibration Procedure

Your exposure should be at a 2 8 or very close to it.

Light meter calibration procedure.

Multiple test points are taken across the full range of the device at intervals based on type of equipment. If you need to maintain the accuracy of your instruments then you need light meter calibration services from acs calibration. The light meter then gathers the reflected or incident light levels as per the type used. 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.

Iso 100 in the external exposure meter and the camera and make sure that all correction values are at 0. The 3 sigma accuracy to the calibrated probe is 3 0 maximum but g r labs standard is a 1 0 window from calibration to calibration. You ll be confident knowing that your instruments will provide accurate measurements. An incident meter should be pointed toward the camera.

We state our traceability to our in house 0 5 nist standard as 3. To calibrate your meter we recommend the following method. Calibrate a light meter firstly you need to hold the meter in front of the subject. 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. Professional light intensity lux meter that measures illumination levels in lux. Set the same iso value e g.

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. This data is then stored for easy 24 7 access within gagesuite our cloud based calibration management system. Switch the camera to manual mode and deactivate all functions that affect the exposure. 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.
