Thank you for purchasing the
multi-parameter tester. Please use
the following instructions to set up
and calibrate your tester before
taking measurements.
There are 3 stages to execute
before using your meter:
STAGE 1 : Conditioning and
temperature calibration
STAGE 2: Setup the system
and the parameters
STAGE 3 : Calibrate the
parameters
BEFORE YOU BEGIN
you must first load batteries,
condition the tester and calibrate
the temperature.
BATTERIES
Twist and unscrew the top
cover and insert the 4 batteries
(LR44 1.5V) as shown in this
picture. Note the polarity.

STAGE 1
CONDITIONING
Condition your tester by
immersing it in tap water for at
least 30 minutes before use.
DO NOT use de-ionized water.
CALIBRATING THE
TEMPERATURE
Before taking measurements, it
is important to calibrate your
tester to read accurately. This
procedure is only done once in
a long while as the calibration
for temperature will remain
accurate unless used under
severe conditions.
FOLLOW THESE STEPS:
1. Press the ON key
The tester is now in
Measurement mode.
2. Place a standard
thermometer in the sample for
reference. If using a mercury
thermometer, allow some time
to reach correct reading.
3. Then place tester into the
same sample. Allow some time
for sensor to stabilize.
4. Press MODE to select the pH
measuring mode. Then press
the CAL key.

5. Press the HOLD key for 5
seconds and wait till screen
changes.
6. Use the cand dkeys to
manually adjust until you reach
the correct temperature of
your sample according to the
reference thermometer.
7. Press ENT to confirm and
return to the PH measuring
mode.
NOTE: Once calibrated, you
don’t have to do this for any
other parameter as
temperature is common to all.
CHANGING THE
SENSOR
