Multiple test points are taken across the full range of the device at intervals based on type of equipment.
Light meter calibration procedure.
An incident meter should be pointed toward the camera.
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.
Our light meter calibration processes ensure that your instruments meets engineering machining parts design quality control and inspection requirements.
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.
Professional light intensity lux meter that measures illumination levels in lux.
Your exposure should be at a 2 8 or very close to it.
If you need to maintain the accuracy of your instruments then you need light meter calibration services from acs calibration.
To calibrate your meter we recommend the following method.
We state our traceability to our in house 0 5 nist standard as 3.
Our light meter calibration procedure requires our experienced technicians to take measurements by direct comparison to a calibrated standard meter and reference source.
You ll be confident knowing that your instruments will provide accurate measurements.
In order for this meter to be exact you need to perform calibration procedure described in the apps s info screen.
This data is then stored for easy 24 7 access within gagesuite our cloud based calibration management system.
Calibrate a light meter firstly you need to hold the meter in front of the subject.
Switch the camera to manual mode and deactivate all functions that affect the exposure.
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.
The light meter then gathers the reflected or incident light levels as per the type used.
What actually happens in our 365nm standard for example is that the.
Iso 100 in the external exposure meter and the camera and make sure that all correction values are at 0.
Set the same iso value e g.
