Testing The Calibration

Testing The Calibration

When the meter is placed atop the spacer and copper faced calibration block the meter should read exactly 14%. My camera was slightly off center but the meter does read spot on when you are directly over it.

So if the meter reads zero when holding it in mid air and 14% when placed atop the calibration block and spacer it's ready to use and in perfect calibration.
