• The meter is supplied complete with batteries. Remove the back cover
and install the batteries, while paying attention to their polarity.
• For better accuracy, make sure that the instrument is calibrated (see
“Calibration” section for details).
• Connect the HI 1217D electrode to the DIN connector on the top of the
instrument and press the ON/OFF key.
• To take a pH measurement, remove the electrode protective cap and
simply submerge the tip (4cm/1½") of the electrode into the sample.
• If necessary, press the RANGE key until the display changes to the pH
mode, and allow for the electrode to adjust and stabilize.
• Since the pH electrode also features a built-in temperature sensor, pH
measurements are automatically adjusted for the temperature effect.
• To take temperature measurements, press the RANGE key to enter
temperature mode, dip the supplied electrode (with built-in temperature
sensor) in the sample and allow for the reading to stabilize.
• After use, switch the instrument off, rinse the electrode with clean water
and store it with a few drops of storage (HI 70300) or pH 7 buffer
solution in the protective cap.
