Safety Instructions
1. Power applied on this appliance should match with the rated
voltage.
2. Stir the electrode gently in the water and avoid letting blebs attach
on the electrodes.
3. For good precision, clean the electrodes regularly with alcohol.
4. If the monitor is not in use for a long time, it must be reactivated by
leaving the electrode in tap water for several hours.
5. Before using the product, please charge its battery for 3 hours first.
6. If the appliance is used indoors, we recommend you to use it with
the included power adaptor.
7. If you use the appliance outdoors, please charge its battery for 3
hours first. The precision of the monitor will decrease after use of 5 to
6 hours.

PH Calibration
1. Prepare 3 small beakers of ph 6.86 , 4.00 and 9.18 solution.
2. Turn on the monitor and immerse the ph electrode into the 6.86
solution. Stir it gently and wait until the reading on display
stabilizes.
3. If the reading is not 6.86 now, use the screwdriver to adjust the PH
calibration button until the reading becomes 6.86.
4. Take out the ph electrode from the solution and rinse it with
alcohol.
5. Put the ph electrode into the 4.00 or 9.18 solution to see if the
reading is correct. If not, readjust the reading to the correct value.
EC/CF/PPM Calibration
1. Prepare 2 small beakers of solution of 12.88 EC and 14.1EC.
2. Turn on the monitor and press the “MODE” button to choose the
“EC” mode.
3. Immerse the EC/CF electrode into the 12.88 EC solution. Stir it
gently and wait until the reading on display stabilizes.
4. If the reading is not 12.88 now, use the screwdriver to adjust the
EC/CF/PPM calibration button until the reading becomes 12.88.
5. Take out the EC/CF/PPM electrode from the solution and rinse it
with alcohol.
6. Put the EC/CF/PPM electrode into the 14.1EC solution to see if the
reading is correct. If not, readjust the reading to the correct value.
