Instruction Manual 3 PREPARATION 3.1 Inserting the Batteries CyberScan pH 11 / 110 This meter is packaged with 4 “AAA” alkaline batteries required for operation. To insert the batteries into the meter, follow the procedure outlined below. 1. To open the battery compartment, press down the catch of the battery cover. See below. 2. Note the polarity and insert the batteries into the battery compartment correctly 3.
Instruction Manual 3.2 CyberScan pH 11 / 110 Connecting the pH Electrode Temperature Probe & Electrode Holder The pH 11/110 meter uses any standard pH, ORP, or Ion Selective Electrode (ISE) with a BNC connector. For Automatic Temperature Compensation (ATC), this meter requires a temperature probe with a phono-jack connector. NOTE: It is important that water does not get into the BNC connector. Also avoid touching the connector with soiled hands. 3.2.1 To connect pH, ORP or ISE electrode 1.
Instruction Manual CyberScan pH 11 / 110 3.2.2 To connect the temperature probe: The temperature probe (provided) uses a 2.5 mm phono jack to connect with the socket on the pH 11/110. Insert the jack fully into the socket (Figure 6). Note: Calibrate your temperature probe when you replace the probe and when using a “3-in-One” combination pH and temperature probe. See section 4.5 - Temperature Calibration on page 16 for instructions. Figure 6: Insert temperature probe 3.2.
Instruction Manual CyberScan pH 11 / 110 1. Align the flange of the second electrode holder with the slot of the first holder (Figure 8). 2. Slide the flange of the second holder into the slot of the first holder until the tops of the holders are aligned and secure. Figure 8: To attach a second electrode holder 3.2.5 Insert the electrode into the holder 1. Do not use excessive force when inserting electrodes into the holders. 2.
Instruction Manual 3.3 CyberScan pH 11 / 110 Connecting the AC/DC Adapter Besides using four AAA-sized batteries as a power source, the pH 11/110 meter can also operate from the power mains using an AC/DC power adapter either at 120/220 VAC (sold separately). This is extremely useful if you have an A.C. power source available (e.g. laboratory). Before plugging in, switch off the meter and the power source of adapter. This is a safety precaution that should be adhered to safeguard your meter. 1.
Instruction Manual CyberScan pH 11 / 110 3.4.1 RS232C Configuration The pH 110 meter has a 9 pin female RS232C connector with the following pin out: PIN NO. DESCRIPTION 1 - 2 Transmit Data 3 - 4 - 5 CTS (Clear to Send) 6 - 7 GND (Ground) 8 - 9 - A one-to-one connection can be made with a 9 pin RS232C port of the computer.
Instruction Manual CyberScan pH 11 / 110 4 CALIBRATION 4.1 Important Information on Meter Calibration When you re-calibrate your meter, previous pH and Relative mV calibration points are replaced on a point by point basis. For example, if you previously calibrated your meter at pH 4.01, 7.00, and 10.01, and you have now re-calibrated at pH 7.00, the meter retains the old calibration data at pH 4.01 and pH 10.01. To view current calibration points, see section 9.3 - P2.
Instruction Manual CyberScan pH 11 / 110 4.2.1 pH 11 meter calibration The pH 11 meter is capable of up to 5-point pH calibration to ensure accuracy across the entire pH range of the meter. You can select from the following buffer options: • USA buffers --- pH 1.68, 4.01, 7.00, 10.01, and 12.45. • NIST buffers --- pH 1.68, 4.01, 6.86, 9.18, and 12.45. 4.2.2 pH 110 meter calibration The pH 110 meter features four separate internationally recognised buffer standards.
Instruction Manual 4.3 CyberScan pH 11 / 110 pH Calibration with ATC NOTE: We recommend that you perform at least 2-point calibration using standard buffers that bracket (one above and one below) the expected sample range. 1. 2. 3. 4. 5. 6. If necessary, press the MODE key to select pH mode. The pH indicator appears in the upper right hand corner of the display. MEAS 7.16 Rinse the probe thoroughly with de-ionised water or a rinse solution.
Instruction Manual 7. 8. 9. CyberScan pH 11 / 110 Rinse the probe with de-ionised water or a rinse solution, and place it in the next pH buffer. CAL READY 4.15 Follow steps 5 and 6 for additional calibration points. See Figure 12. When all the calibration points set in the Unit Configuration Setup (see P1.3 Select Number of pH Calibration Points on page 36) are completed, the meter returns to Measurement mode automatically.
Instruction Manual 4.4 CyberScan pH 11 / 110 mV Calibration (Offset) (Only for pH 110) With pH 110 meter, you can perform a calibration or an offset of up to ±150 mV.

Instruction Manual 14 CyberScan pH 11 / 110 INFORMATION ON pH MEASUREMENT & ELECTRODE The previous sections of this manual describe the various features of the instrument and practical aspects of its operation. This section provides a general description of pH measurement principles. It also provides tabulations of pH buffer changes with temperature. Lastly, it includes a list of available accessories. 14.1 pH Measurements 14.1.
Instruction Manual CyberScan pH 11 / 110 14.1.3 pH and Temperature The electromotive force generated in the glass electrode varies with the temperature of the solution. As a result the response of the pH electrode is subjected to variations in temperature. Automatic Temperature Compensation compensates for this variance. A solution’s temperature dependence varies considerably. Some may show an increase in pH while others a decrease for the same temperature variation.
