Operating Instructions:
•
•
Connect the electrode to the meter (both the printings on the body and on the electrode facing upwards, see Fig. 1-2). Turn
the meter on by the OFF/pH/°C switch and select the pH position.
the meter on by the OFF/pH/°C switch and select the pH position.
•
Dip the electrode into the solution. Under no circumstances the immersion shall be above the max. level printed on the rear.
•
Stir gently until the display shows a stable reading. The instrument will automatically compensate for the temperature
variation.
variation.
•
Before dipping into a new sample, in order to get an accurate measurement, it is recommended to rinse the electrode with
the sample solution.
the sample solution.
•
It is necessary to replace all 3 x 1.4V batteries when the display becomes faint or the reading is unstable (to replace them
see Fig.3). Battery replacement must only take place in a non hazardous area using the battery type specified in this
instruction manual.

instruction manual.
Calibration:
•
•
Single point calibration: dip the electrode into a buffer solution close to the operating range and adjust the value by the
OFFSET calibration trimmer (see Fig. 4).
OFFSET calibration trimmer (see Fig. 4).
•
Dual point calibration: dip the electrode into HI 7007S buffer solution (pH 7.01 @ 25ºC) and adjust the reading by the
OFFSET calibration trimmer to the pH value corresponding to the buffer solution temperature. Dip the electrode into
HI 7004S buffer solution (pH 4.01 @ 25ºC) or HI7010 (pH 10.01 @ 25ºC) and adjust the reading by the SLOPE calibration
trimmer to the pH value corresponding to the buffer solution temperature (see Fig. 4).

Maintenance:
•
•
If the electrode remains dry for a long period, before taking any measurement or calibrating, it is necessary to reactivate it
by dipping into HI 70300 solution for about 4 hours. The electrode should be cleaned after use and stored covered by the
cap with some HI70300 inside.

Recommendations for Users:
Before using this product, make sure that it is entirely suitable for the environment in which it is to be used. Operation of this instrument in
residential area could cause unacceptable interferences to radio and TV equipments, requiring the operator to take all necessary steps to correct interferences. The glass bulb at
the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times. During operation, ESD wrist straps should be worn to avoid possible
damage to the electrode by electrostatic discharges. Any variation introduced by the user to the supplied equipment may degrade the instrument's EMC performance. To avoid
electrical shock, do not use this instrument when voltages at the measurement surface exceed 24VAC or 60VDC. To avoid damages or burns, do not perform any measurement
in microwave ovens.
