Series The pH 510 and Ion 510 bench meters are microprocessor-based which incorporates new ASIC (Application Specific Integrated Circuit). It is designed with convenience in mind, and offers many advanced user-friendly features. The meters are capable of storing and recalling up to 50 data sets in its non-volatile memory. In addition, as a space saver, an optional swivel electrode holder can be attached at the either side of bench meter for resting the electrodes and probes during operation. The pH 510 meter is capable of measuring pH/ORP with Temperature; while the Ion 510 meter measures Ion Concentration/pH/ORP with temperature. It is equipped with a large customized LCD (Liquid Crystal Display) with simultaneous display of the measured values for easy reading. It is most ideal for routine pH/Ion Concentration measurement in indoor applications. 1.2 Custom LCD The 510 meter is characterized by a large custom dual LCD. The display has mode annunciators for pH, mV, ppm and temperature readings. The secondary (lower) display shows the temperature reading simultaneously with the primary (upper) display that shows the measured values of pH, ppm or mV. Special annunciators such as units of measure, error message, graphical icons and modes of operation are arranged around both primary and secondary display to give you a comprehensive yet uncluttered display. SETUP ­ The meter is in SETUP mode. MEAS- The instrument is in the measurement mode. CAL - The instrument is in the calibration mode. MEM- Data is stored into memory READY- The measured value has stabilized. SETUP READY HOLD MEAS CAL MEM R.mV pH ppm HOLD- The displayed value has been frozen. Shows the respective mode of operation. ERR - An error in operation has occured. ERR CF pH ATC Buffer - Prompts user to select buffer during calibration, or indicates buffer error when flashing together with the ERR annunciator. ELECTRODE- indicates electrode error when it appears with ERR. pH ­ Indicates buffer values of respective USA or NIST buffer option set. ATC (Automatic Temperature Compensation) activated. If ATC is not displayed, temperature probe is not connected. In this case the Manual Temperature Compensation is activated. 1 Instruction Manual pH 510/ Ion 510 1.3 Keypad A large splash proof membrane keypad with tactile feedback makes meter easy to use. Names and symbols describe the function button controls. Key ON/OFF Measurement Mode Powers the meter ON/OFF. When the meter is switched on, it automatically starts in the last mode of operation. Toggles between the measurement and calibration modes of the meter. In SETUP mode, pressing CAL/MEAS key returns to the measurement mode. Toggles between the different measurement modes available pH/Temperature/mV/Ion. (Ion mode only applies with the ION 510.) MI inputs measurements into memory and scrolls through memory values. Calibration / Setup Mode ~ CAL/MEAS ~ MODE Switches from pH to Temperature in pH calibration mode scrolls values in mV calibration mode and selects temperature values and ion options in calibration mode. Scrolls to next program in the SETUP mode. scrolls values in mV calibration mode and selects temperature values and ion options in calibration Scrolls to next program in the SETUP mode. ~ Confirms and enters the value selected for calibration. MI/ MR/ MR recalls measurements from memory and scrolls through memory values. HOLD ENTER Freezes a measurement on the display. Press again to get current readings. Enter functions in the memory mode. You can also configure functions like Meter Reset, Memory Clear and Selection of pH Buffer Standard via the keypad. Please refer to Section 5 for more information on the above functions. 2 Instruction Manual pH 510/ Ion 510 1.4 Rear Instrument Panel This 510 series meter provides a complete set of connectors for the various accessories commonly used. Listed in the table are the details of the connections that you can make. Rear View of Meter Connection ATC INPUT REF REC GND DC Function For phono jack connection from the temperature probe for Automatic Temperature compensation. The probe should be a 30K thermistor type. For connection to sensor electrodes with BNC type connectors. The meter accepts any pH, ORP or ISE with BNC connector. Always ensure that the connector is clean and dry. For connection to pin type reference electrode normally used with half cell (mono) type pH electrodes or ISEs. For connection to strip chart recorders. Use subminiature plug with positive tip. For connection to the ground earth jack (standard tip connectors). For connection for the AC/DC power adapter 3 Instruction Manual pH 510/ Ion 510 2 STARTING UP Connect the accessory connectors at the rear of the instrument panel. During operation, it is important that water does not get onto the BNC connector. Also avoid touching the connector with soiled or wet hands. 2.1 Connecting the Sensor Electrode Slide the electrode connector of the electrode over the socket of ...
