ATTENTION
NEVER use the product when it’s freezing cold. Let it warm to room temperature
before using.
NEVER use your nger to touch the pH glass membrane or use other materials to
rub it. Doing so could generate static electricity and cause measurement errors. To
remove extra water on electrode, just shake it o or blot dry with Kimwipe or clean
tissues.
HandlethepHelectrodewithcare.It is made of glass, and will break if dropped
or bumped against hard objects.

Search “zentest” in Apple App Store or Google Play App Store to download the
latest App for your meter. Make sure the Bluetooth of your phone is turned on, then
go to ZenTest App, tap on the upper right corner, then select your meter to
connect (NOT the Demo device).
The content of this user mnual focus on how to operate through the meter's keypad.

ShortPress — 1 second LongPress — 3 seconds
• When turned o, short press to turn on the tester; long press to
enter parameter setting.
• In calibration mode or parameter setting, short press to return to
measurement mode.
• In measurement mode, long press to turn o the tester, short press
to turn on/o backlight.
• In measurement mode, long press to turn on/off Bluetooth®
receiver. When it's turned on, will be flashing; when it's
connected to smartphone, will stay on.
• In parameter settings, short press to change parameter (Uni-
directional).
• Long press to enter calibration mode.
• In calibration mode, short press to conrm calibration.
• In measurement mode, when Automatic Hold is turned off, short
press to manually lock or unlock readings; when Automatic Hold is
triggerd, short press to unlock the reading.
4.1.4 Wait for the reading to stabilize (when stays on the screen), then short press
again to nish the rst point calibration (pressing too early could lead
to Er2 error). "7.00" will be ickering and the meter will return to measurement
mode. Icon (the middle point) will appear at the bottom left, indicating a
successful 1-point calibration.
4.1.5 To calibrate the 2nd point, rinse o the electrode with pure water and remove
excess water. Dip the electrode into pH 10.01 solution and repeat Step 4.1.3 to
4.1.4. "10.01" will be ickering and (the high point) will show up next to
, indicating a successful 2-point calibration.
4.1.6 To calibrate the 3rd point, rinse o the electrode with pure water and remove
excess water. Dip the electrode into pH 4.00 solution and make a quick stir, then
repeat Step 4.1.3 to 4.1.4. "4.00" will be flickering and (the low point) will
display next to and , indicating a successful 3-point calibration.
4.2 NotesaboutCalibration
4.2.1 Always start calibrating with pH 7.00 first. Perform the 2nd and 3rd point
calibration immediately after the 1st point is finished. Do NOT turn off the
meter before you calibrate the second or third point. Otherwise, after you
restart the meter and perform calibration in pH 4.00 or pH 10.01, Er1 error
will be generated and you will have to calibrate with pH 7.00 again. For more
troubleshooting tips with calibration, refer to Section 14.
4.3HowOftentoCalibratetheElectrode?
The frequency that you need to calibrate your pH Electrode depends on many factors such
as the nature of test samples, condition of electrodes, and the requirement of the accuracy.
For high-accuracy measurements (≤ ±0.02pH), the electrode should be calibrated before
every test; For general-accuracy measurements (≥ ±0.1 pH), calibrate the electrode every 1-2
weeks.
Inthefollowingcases,theelectrodemustbere-calibrated:
• The electrode hasn’t been used for a long time or a dierent electrode is connected.
• After measuring strong acid (pH<2) or strong base (pH>12) solutions.
• After measuring uoride-containing solution and strong organic solution.
• There is a significant temperature difference between the test sample and the buffer
solution.
5.1HowtoTakepHMeasurement
5.1.1 Short press to power on. Remove the storage
sleeve and rinse the electrode in distilled/
deionized water, then shake o the excess.
5.1.2 Submerge the electrode into your sample solution
at least 1 inch deep, make a quick stir and hold
still. Record the reading as the pH measurement
when it is stabilized ( comes up and stays on
screen).
Soak the electrode in pH 4.00 calibration solution for half a minute
5.3TipstoGetMoreAccuratepHMeasurementofPureWater
When testing pure water like tap/drinking/well/RO/distilled/deionized water, it will
take longer for the readings to get fully stabilized (typically 2-5 minutes). Pure water
is susceptible to the influence of CO2 in the air. If you leave the electrode in pure
water for too long, its pH will be slowly changing. Here are some tips to minimize
this interference:
• Use a closed system — Minimize the time that the water sample is exposed to the
air before and during the pH measurement. Use a lid or cover on top of the water
sample and make a hole to insert the electrode for testing when possible.
• Use a degassed sample — Before measurement, degas the water by boiling it for
a few minutes. Boiling will drive o most of the dissolved gases, including CO2.
After boiling, quickly cool the water under an inert atmosphere (like nitrogen or
argon) to prevent the re-dissolution of CO2 and then measure the pH immediately.
6.1 Themeterisonlyasaccurateastheelectrodeisclean.Always thoroughly rinse o
the electrode before and after each measurement with distilled water in a container
or with a wash bottle. To remove excessive water, just shake them o or blot dry
with Kimwipe or lint-free cloth. Neverrub the glass membrane of the electrode.
Otherwise static electricity will be generated and cause measurement error.
6.2 For tough contaminants stuck on electrode, use a soft brush and warm soapy water to
clean them o; If not working well, soak the electrode in the Apera electrode cleaning
solution (SKU: AI1166) for 30 to 60 minutes, and use a soft brush to remove the
contaminants. After the cleaning, soak the electrode in the 3M KCL solution for 12 to 24
hours, then perform a 2 to 3 point calibration before taking a new pH measurement.
