OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE INITIAL PREPARATION The instrument is supplied with batteries. In order to place the batteries inside the instrument follow the instructions from page 16. To prepare the instrument for use, connect the pH electrode and the temperature probe to the BNC and temperature sockets on the top of the instrument. - Page 8 The LCD will show the pH measurement and the temperature of the sample. 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 value of the sample is directly affected by temperature.
- Page 9 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. Submerse the ORP electrode 3 cm (1¼”) into the sample to be tested and wait a few minutes for the reading to stabilize.

BATTERIES REPLACEMENT BATTERIES REPLACEMENT BATTERIES REPLACEMENT BATTERIES REPLACEMENT BATTERIES REPLACEMENT The instrument is supplied with batteries. First time you start working with the instrument, insert the supplied batteries in the battery compartment observing the correct polarity (see page 17). At start-up the battery percentage is displayed. If the batteries become weak, the display will flash the battery symbol to advise the user that approximately 1 hour of working time remains. - Page 17 To replace the batteries, follow the next steps: • Turn the instrument OFF. • Open the battery compartment cap (located on the top of the instrument). • Remove old batteries. • Insert three new 1.5V AAA batteries in the battery compartment, observing the polarity on the rear of the instrument.
