The LCD will show the pH measurement and the temperature of the
sample.
In order to take more accurate pH measurements, make sure that the
instrument is calibrated (see page 9 for details).
The glass bulb and the junction on the pH electrode should always be
moist, never allow it to dry out.
If several measurements are taken successively in different samples,
rinse the electrode thoroughly with deionized or tap water and a
small amount of the sample to be measured.
The pH reading is directly affected by temperature. In order for the meter to
measure the pH accurately, temperature must be compensated for. If the
sample temperature is different from the temperature at which the pH
electrode was kept, allow a few minutes for thermal equilibrium.
To use the meter's Automatic Temperature Compensation feature,
submerge the temperature probe into the sample as close to the
electrode as possible and wait for a few minutes.
If manual temperature compensation is desired the temperature
probe must be disconnected from the instrument
.
The display will show the default temperature of 25 °C, or the last
temperature set with the "°C" (or "°F") indicator blinking.
The temperature can now be adjusted with the UP and DOWN arrow keys.
ORP MEASUREMENTS (HI 9125 only)
To perform ORP measurements, connect an optional ORP electrode
(see "Accessories" section) to the meter and turn it ON.
If necessary, enter the "mV" mode by pressing RANGE until the
display changes to mV.
