OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Remove the
battery compartment cover on the back of the meter and install the
battery while paying attention to its polarity.
Connect the probe to the DIN socket on the top of the meter by
aligning the pins with the socket and pushing in the plug.
Always remove the probe protective cap before taking any measure-
ments, and make sure the meter has been calibrated.
Turn the meter on by pressing the ON/OFF key.
TAKING pH MEASUREMENTS
If the probe has been left dry, soak the tip in HI 70300 storage
solution for a few minutes to reactivate it.
• To take a pH measurement simply submerge the
tip (4cm/1½") of the probe into the sample to be
tested.
• Select the pH mode.
• Stir briefly and wait a couple of minutes
for the reading to adjust and stabilize.
The display shows the pH value.
• If measurements are taken in different samples successively, it is
recommended to rinse (clean) the probe thoroughly to eliminate
cross-contamination. After cleaning, it is recommended to rinse
the probe with some of the next sample to be measured.
TAKING EC/TDS MEASUREMENTS
• Immerse the tip of the probe (4cm/1½") into the
sample to be tested. If possible, use plastic
beakers or containers to minimize any EMC inter-
ference.
• Tap the probe lightly on the bottom of the
beaker to remove any air bubbles which may be
trapped inside the tip.
