CHECK CALIBRATION Press the calibration check button @. Meter is in calibration if the needle pointer moves to "20" on the scale. Any reading within the green band on the dial is acceptable. Make sure the contact pins are not in contact with anything when checking the calibration. If you check the calibration and the needle does not read within the green band, it is likely an indication of a low battery. If this occurs, change the battery immediately.
