Operating Manual for the Accurate PPM 5.0 Meter

1. Remove the protective electrode cap and at the top of the meter and push
the switch to the ON position.
2. If you are using this meter for the first time or the meter has not been
used for a long time you will need to calibrate it for accurate readings.
Skip to the calibration section then return to step 3.
3. Dip the meter's electrode into a small sample of the solution to the
immersion level as shown. Stir gently to dislodge air bubbles, stop and
wait for two minutes for the temperature compensation display value to
stabilize. The display number is the PPM (parts per million) value of the
solution. Note: The meter is not waterproof. Never dip the meter into a
large body of solution as you may drop it in and ruin the meter. Test small
samples only. See pictures. For complete temperature compensation,
allow the meter's display reading to stabilize for up to 2 minutes.
4. Immediately after finishing your test, dip or rinse the electrode in distilled
water. Stir gently. Then use tissue paper or a soft cloth to blot the excess
water from the meter's body and the electrode's two metal pins. Replace cap. Note: As
with all quality PPM meters, do not allow the solution that you are testing to dry on the
electrode's metal pins. Also, blotting action must be carefully done in order not to
damage the metal pins.
5. When storing the PPM meter, switch the unit to the OFF position. Complete step 4. After
step 4, put the cap onto the PPM meter and store it in a cool place out of direct sunlight
and moisture. For extended storage time take the batteries out of the meter. Do not store
with the meter's electrode submerged in water or solutions.
If the unit cannot be switched ON or the display fades replace all of the batteries with
new batteries. Use only one brand of batteries. Never mix battery brands.
