Instruction Manual 1 CON 510 INTRODUCTION Thank you for selecting the CON510 bench meter. This meter is a microprocessor-based instrument that is designed to offer advanced yet user-friendly features for discerning users - ideal for laboratory and plant applications. It measures Conductivity, Total Dissolved Solids (TDS) and temperature (oC/oF). It incorporates large memory capacity of up to 50 data sets and user-customisable functions – all are accessible through the membrane tactile keypad.
Instruction Manual 2.2 CON 510 Keypad The splash-proof membrane tactile keypad allows easy key entry. Each button, when pressed, has a corresponding graphic icon or indicator displayed on LCD. Some buttons have several functions depending on its mode of operation. Key Function ON/OFF Powers on and shuts off the meter. When you switch on the meter, the meter starts up in the mode that you last switched off from.
Instruction Manual 3 3.1 CON 510 PREPARATION Conductivity Electrode Information The CON510 bench meter is supplied with a Conductivity/TDS electrode (with a sturdy locking 6-pin connector). This Conductivity/TDS electrode (Code No: ECCONSEN91W/ 35608-50) comes with Stainless Steel rings, cell constant of K = 1.0, and a built-in temperature sensor for Automatic Temperature Compensation (ATC). Its specially designed Ultem-body housing has good chemicalresistant properties.
Instruction Manual 3.4 CON 510 Connecting the Electrode Holder The integral electrode holder serves as a handy holder for a few electrodes or a separate temperature probe during measurement or when not in use. This 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 Phillips screwdriver to remove the screw holding the electrode holder.
Instruction Manual 4 CON 510 CALIBRATION 4.1 Important Information on Meter Calibration The CON 510 bench meter allows you to perform automatic calibration (only for Conductivity mode) or manual calibration (applicable to both Conductivity/TDS mode). The meter can calibrate either single point or multi-point up to 5 calibration points (manual mode) with a maximum of 1 point in each measurement range.
Instruction Manual CON 510 Normalization Temperature: The factory default value for normalization temperature is 25 °C. If you need to normalize to a value other than 25 °C, see SETUP sub-menu P4.2. 4.2 Preparing the Meter for Calibration Before starting calibration, make sure you are in the correct measurement mode. Otherwise press MODE key to toggle between measurement modes. When you switch on the meter, it starts up in the last unit of measure when you last shut off the meter.
Instruction Manual 4.6 CON 510 Automatic Calibration (Only for Conductivity) In the automatic calibration mode, the CON 510 bench meter is capable of accepting either single-point or up to 4 points for multi-point calibration with maximum of 1 point per specific measurement range using known calibration standards values which include: 84 µS/cm (0 – 200.0 µS/cm), 1413 µS/cm (0 – 2000 µS/cm), 12.88 mS/cm (0 – 20.00 mS/cm) and 111.8 mS/cm (0 – 200.0 mS/cm). NOTE: You need to set your desired option i.e.
Instruction Manual 4.7 CON 510 Manual Calibration (Conductivity/TDS) The meter accepts either single point or multi-point (up to 5 points) manual calibration with maximum of 1 point per measurement range. Freshly prepare your standards solution before calibration. Refer to the table in Section 4.1 for more details of the recommended standards calibration range. MODE MEAS READY uS . You can offset or manually adjust the Conductivity or TDS reading up to ±40% from its default setting.
Instruction Manual 4.8 CON 510 Temperature Calibration The Conductivity electrode (EC-CONSEN91W/ 35608-50) has a built-in temperature sensor for ATC. The temperature sensor is factory calibrated to the meter. Calibrate your sensor only if you suspect temperature errors that may have occurred over a long period of time or if you have a replacement probe. Temperature Calibration 1. Make sure the electrode is attached to the 6-pin connector. 2. Power the meter on.
Instruction Manual 5 CON 510 MEASUREMENT The CON 510 bench meter measures up to 5 different measurement ranges with auto-ranging capability which automatically detects and promptly switches to the appropriate range. The meter also allows measurements to be taken with automatic or manual temperature compensation. The factory default is ATC on. ATC basically compensates for any temperature variances of measured sample solution temperature automatically from the normalization temperature set.
Instruction Manual 5.2 CON 510 Manual Temperature Compensation NOTE: For manual temperature compensation, you must deactivate the ATC mode to ‘nO’ as shown in SETUP submenu P3.3. 5.2.1 Setting a manual temperature compensation value To set manual temperature compensation value, you need to determine and enter the desired temperature value into the meter. This value is based on which reading will be manually temperature compensated. You may select any temperature between 0 and 100 °C (32 to 212 °F).
Instruction Manual 5.4 CON 510 Using Manual Ranging Function Although the CON 510 bench meter has an automatic ranging capability, you may also manually select any specific measurement range you wish to work on by pressing RANGE each time for every range. ENTER RANGE MEAS READY Range Indicator Conductivity Range uS TDS Range (if TDS factor is 0.5) r1 0 – 20.00 µS/cm 0 – 10.00 ppm r2 0 – 200.0 µS/cm 0 – 100.0 ppm r3 0 – 2000 µS/cm 0 – 1000 ppm r4 0 – 20.00 mS/cm 0 – 10.
Instruction Manual 6 6.1 CON 510 MEMORY AND DATA INPUT FUNCTIONS Memory Input The meter’s non-volatile memory can store and recall up to 50 data sets which include Conductivity and temperature or TDS and temperature.
