4. Select a clean and dry vial, un-screw the cap and fill with sample
water to the line on the vial. Replace the cap, ensuring it is screwed
on finger tight to the vial.

or finger-prints. Gently push the vial fully into the meter, whilst
aligning the ▼ mark on the vial with the ▲ mark on the meter.
6. Press the ZERO key to blank the meter to that vial; the meter will
read [ZERo] whilst this is taking place.
Note: The meter will store the last zero value it took between tests, even if it
turns off or if the batteries are removed.

Note: a small amount of the powder may remain un-dissolved in the vial, but
this will not affect the reading.
