This step-by-step instruction manual gives you a detailed description on the use and operation of features on the meter. This PC 510 pH and Conductivity bench meter is designed to be user-friendly while providing unprecedented levels of accuracy, repeatability and reliability. The PC 510 is an advanced microprocessor-based (ASIC - Application Specific Integrated Circuit) ideal for routine measurement that best meets discerning user's individual needs. This multi-parameter meter reads pH, mV, Conductivity, Total Dissolved Solids (TDS) and temperature (°C or °F). It has splash-proof keypad, simultaneous pH/mV/Conductivity/TDS and temperature display on a large angled custom LCD. This instruction manual is illustrated with useful hints and diagrams that show which specific key-presses to access for each function. 2 METER INFORMATION The PC 510 meter is packaged in a corrugated box that is made of environment-friendly materials and can be re-cycled. 2.1 Meter parts The instrument is designed to give an aesthetic look as well as ergonomic functionality. A large custom dual LCD is provided at an angle for optimum viewing. A splash-proof keypad with audible tactile response gives you a good feel of the instrument. A slide-out instruction card offers a handy reference. Listed below are the major components of the meter. 2.2 Customised LCD The PC 510 bench meter is characterised by large dual custom LCD (Liquid Crystal Display). The display has also mode annunciators for pH, temperature, mV, conductivity and TDS readings. The secondary (lower) display shows the temperature readings simultaneously with the primary (upper) display of measured mode. Special annunciators such as graphical symbols, error messages, measurement units and modes of operation are arranged around the primary and secondary displays to give a comprehensive display. The integration of graphics and error messages into the LCD provides you a higher level of user-friendliness and easy readability. 2.3 Slide-out card A plastic slide-out card is provided at the bottom of the PC 510 bench meter. The function of this card is to provide a quick guide to the functions of the individual keys as well as to provide a useful troubleshooting reference. 2.4 Rear instrument panel The PC 510 bench meter provides three connectors at the rear of the meters. These connectors are labeled CON/TEMP, pH and DC. CON/TEMP pH DC Figure 1 : View of meter rear panel 1 Instruction Manual PC 510 Connector CON/TEMP pH DC Function For connecting 6-pins conductivity/TDS sensor with built-in temperature sensor to the meter or optional temperature probe for use with pH electrode (when applicable). Always make sure that the connector is clean and dry. For connecting pH sensor with a BNC connector to the meter. Always make sure that the connector is clean and dry. For connection to the AC power source to the power jack (DC). 2.5 AC/DC adapter The AC/DC adapter converts the power mains voltage 120/220 VAC to low DC voltage for the PC 510 bench meter operation. Two basic models of adapters are available depending upon power supply specification of each country. Description AC Adapter 120 V AC Adapter 220 V Order Code EC-120-ADA / 35615-07 EC-220-ADA / 35615-08 Voltage 110-120 V, 50-60 Hz 220-240 V, 50-60 Hz 2.6 Electrodes Your meter includes two probes: · · pH electrode with BNC connector conductivity probe with built-in temperature sensor with a notched 6-pin connector The temperature sensor built into the conductivity probe will also compensate for pH readings as long as both probes are in your solution at the same time. If you want to use a "3-in-1" pH probe with a built-in temperature sensor, or if you want to use a separate temperature probe, you will need to disconnect the conductivity probe to allow for connection of the separate temperature sensor. 2.7 Electrode holder The integral electrode holder serves as a handy holder for mounting the pH and conductivity/temperature probes during measurement or when idle. The bench meter's base plate has a side metal bar to which you can attach an integral swivel electrode holder. You can mount the electrode holder on either right or left side of the meter. To position the electrode arm: Use a Philips screwdriver to remove the screw holding the electrode holder. Slide the side metal bar until the second screw holder. slot lines up with the original screw hole. Use the screw removed earlier to secure the electrode holder into position. Note the side 3 KEYPAD FUNCTIONS metal bar is reversible. If desired, remove screw holding electrode holder base and slide out of brackets. Slide base into brackets on opposite side and tighten screws. See Figure 2.

All keys have primary function rod on the side bar, align the slot with the secondary functions. metal rod and base of electrode arm. Push it downwards until it fully sits into position. Avoid using excessive force when fixing or removing. The electrode arm is ready for use. NOTE: Move the base of electrode holder if you wish to swing the electrode holder about. To prevent the meter form toppling over causing accidental spills, DO NOT swing the body of the electrode holder. 2 Side Metal Bar Figure 3: Installing the electrode arm Instruction Manual PC 510 HO LD O N/ O FF O M DE ER E NT NG EA R T SE L CA AS E M Figure 4: Keypad ON/OFF SET Powers the meter on or off. When meter is switched on, it starts in the mode the meter was last in when powered off. Enters advanced setup mode. SETUP mode lets you customise meter preferences and defaults, and view calibration and probe data. Measurement: Press MODE to toggle between pH, mV, conductivity and TDS. MODE Calibration: In calibration mode, press MODE to access temperature calibration. Freezes the measured reading. To activate, press HOLD while in measurement mode. To release, press HOLD again. HOLD Note: When auto endpoint feature is switched on, meter automatically holds reading after 5 seconds of stability. The HOLD indicator appears on the display. Press HOLD to release auto endpoint feature. Toggles between Calibration and Measurement mode. Example: If you are in pH measurement mode, press CAL/MEAS to enter pH calibration mode. CAL/MEAS Note: Temperature calibration is available from pH, TDS or Conductivity calibration mode. In Setup mode: Press CAL/MEAS to return to main menu from sub menus. Press CAL/MEAS again to return to measurement mode from main menu. ENTER: Press to confirm values in Calibration mode and to confirm selections in Setup mode. RANGE: Press to switch to manual ranging in Conductivity or TDS mode. Press in Setup mode to scroll up through subgroups. Also lets you increase the values in the conductivity, TDS and temperature calibration modes. Press in Setup mode to scroll down through subgroups. Also lets you decrease the values in the conductivity, TDS and temperature calibration modes.
