Page 21: Initial Preparation
INITIAL PREPARATION • Connect a 3‑wire cable to the power supply terminal according to the voltage level as indicated, and pay particular attention to the correct line, earth and neutral connections. • For BNC electrodes, connect the electrode to the BNC plug on the rear panel. The instruments are equiped with differential input. - Page 22 Connect the “+” wire of the recorder to the terminal 1 on the instrument and the other wire (common) to terminal 2 for 4‑20 mA recorder output or to terminal 3 for 0‑20 mA recorder output. Note: Only one recorder output connection is possible. In order to avoid malfunction leave the unused terminal unconnected.

Page 24: Operational Guide
OPERATIONAL GUIDE All instrument settings are made via front panel keys and trimmers. When a key is pressed, the corresponding LED lights up to show the operating function. If the LED blinks before pressing the key, it will change the blinking style. If using an asigned electrode, make sure that the meter is calibrated before starting any operation (see “Calibration”... - Page 25 Using a small screwdriver adjust the COARSE and FINE trimmers to display the desired set value. SET POINTS (HI8711) To set the working point for alkaline dosage, press the ALK. SET key and the display will show the set value for alkaline dosage. The ALK. SET LED will turn ON if alkaline dosage is deactivated or change blinking style.
- Page 26 Note: The ALK. and the ACID setpoints can be set on the entire range 0.00 pH to 14.00 pH using COARSE and FINE trimmers. In order to avoid erroneous situations the ALK. setpoint value should not exceed the ACID setpoint value. ALARMS (HI8710, HI8711 and HI8720) To set the alarm tolerance, press ∆ALARM key and the display will show the current value.

Page 28: Ph Calibration
Two DOSAGE MODE switches are designed for HI8711, one for ACID and the other for ALK. channels. If for any reason one of them is in OFF position the corresponding dosing relay is deactivated. The alarm relay will be activated only in accordance with the other channel. The ALARM LED will work as in AUTO mode. - Page 29 Rinse pH electrode and the reference thermometer thoroughly with pH4.01 rinsing solution, then immerse them in pH4.01 (HI7004) or pH10.01 (HI7010) buffer solution. Note: For accurate readings, use pH4.01 if you are going to measure acid samples or pH10.01 for alkaline measurements. Shake briefly and wait one minute before adjusting the SLOPE trimmer to display the ph value of the buffer solution, i.e.

Page 31: Ph Diagnostic Tests
DIAGNOSTIC TESTS HI8510, HI8710 and HI8711 are provided with autodiagnostic func‑ tions that allow to check and troubleshoot any malfunctioning. The functions are made via front panel keys to isolate the cause of malfunction whether it is due to pH electrode contamination, internal offset circuit or amplifier circuit. - Page 32 C) Amplifier Circuit Test Press the pH4 TEST key and the display should show a value within the 3.30 to 4.30 pH range, to verify the amplifier circuit of the meter. The corresponding LED turns on.

Page 33: Orp Diagnostic Tests
ORP DIAGNOSTIC TESTS HI8512 and HI8720 are ORP controllers provided with autodiagnostic functions that allow to check and troubleshoot any malfunctioning. The functions are made via front panel keys to isolate the cause of malfunction. For HI8720 only, press MEASURE key before proceeding with the following tests. -

LED INDICATION All LEDs above the keys indicate the state of each function, whether it is active or the display is indicating the mode. For HI8711 only Each LED can be in one of the following states: A) Light on The mode is displayed on the LCD but is not active, e.g. -
Page 35: Taking Redox Measurements
TAKING REDOX MEASUREMENTS Redox measurements allow the quantification of the solution oxidizing/ reducing power, and are commonly expressed in mV. Oxidation may be defined as the process during which a molecule (or an ion) loses electrons and reduction as the process by which electrons are gained. - Page 36 Oxidizing pre‑treatment: immerse the electrode for some minutes in HI7092 solution. If no pre‑treatment is performed, the electrode will have long response times. If working with refillable electrodes, always check the internal electrolyte level and refillwith HI7071 solution, if necessary (the level must be at least 2.5 cm below the filling hole).

Page 37: Electrode Maintenance
ELECTRODE MAINTENENCE PREPARATION PROCEDURE Remove the protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is nor‑ mal with electrodes and they will disappear when rinsed with water. During transport tiny air bubbles may form inside the glass bulb, and the electrode cannot function properly under these conditions. - Page 38 Refill the electrode with fresh electrolyte solution (HI7071 for single junction electrodes or HI7082 for double junction). Allow the electrode to stand upright for 1 hour. Follow the above “Storage Procedure”. AmpHel is a registered Trademark of “Hanna Instruments” ®...
