Measuring the Checking Standard
It is recommended that the checking standard is measured weekly or after moving or
transporting the unit.
Visually inspect the standard before measurement- it should be free of dust and
contamination
Place the standard on the instrument.
The standard is held in place by magnets; ensure that the back of the standard is aligned
with the edges of the instrument body.
Press the READ icon.
Compare the measured values with those recorded on the check standard, if the values
are within the stated tolerance the instrument is ready to use.
Please note that the Sharpness value is sensitive to positioning, slightly adjust the
position of the standard if the value is out of tolerance.
Cleaning of the checking standard- the surface of the checking standard is delicate and
should not be touched with any cleaning cloth.
If dust or debris is present on the standard blow the surface with an optical grade dry air
aerosol.
If the standard becomes damaged or contaminated please contact
for more advice.
In case of the standard measuring out of tolerance- repeat the tare process and re-
measure, if the problem persists contact [email protected] for more
advice.
