OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE INITIAL PREPARATION The meter is supplied with batteries (for details see page 19). 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 7 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 10 for details). The glass bulb and the junction on your electrode should always be moist, never allow it to dry out.
- Page 8 ORP MEASUREMENTS 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. Submerse the ORP electrode 3 cm (1¼”) into the sample to be tested and wait for the reading to stabilize.
- Page 9 Note: While in MEM mode, the user can switch between pH and mV by pressing the RANGE key. A stored value can be recalled by pressing MR: the display will show the memorized reading and the “RECALL MEMORIZED” tag, as long as the MR key is pressed.

- Page 12 Note: During calibration, the secondary LCD shows the selected buffer value; press RANGE to display the buffer temperature. Note: To clear a previous calibration and return to the default values, press CLR at any time after entering the calibration mode. The LCD will show “CLr CAL” for one second, and then will return to normal measurement mode.

The meter will continue calibration as with memorized buffers. • The meter will display “C2”. Use the arrow keys to change the value of the second custom buffer, or press CUST BUF to select a memorized...

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 20). 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 20 To replace the batteries, follow the next steps: • Turn OFF the instrument. • 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.

PREPARATION PROCEDURE Remove the electrode protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with electrodes and they will disappear when rinsed with water. - Page 24 For refillable electrodes, if the refill solution (electrolyte) is more than 2½ cm (1") below the fill hole, add the appropriate Electrolyte Solution. MEASUREMENT Rinse the electrode tip with distilled water, submerse it 3 cm (1¼”) in the sample and stir gently for a few seconds. For a faster response and to avoid cross contamination of the samples, rinse the electrode tip with the solution to be tested, before taking any measurements.
