Instruction Manual PCD 650 3. Calibration Mode 3.1 About Calibration PCD 650 series meters are factory calibrated and allows you to measure pH/mV/ion/conductivity/resistivity/TDS/salinity/DO(%)/DO(mg/L). Calibrate to all measurement ranges to ensure the highest accuracy throughout all measurement range. However, it is recommended that, for higher accuracy, you calibrate your meter before you make measurements for the first time.
Instruction Manual PCD 650 The meter automatically recognizes and calibrates to these standard pH buffer values, which makes pH calibration faster and easier. 3.1.3 About Ion Calibration The meter supports Ion calibration up to 8 points with minimum of 2-points. The available 8-points are 0.001, 0.01, 0.1, 1, 10, 100, 1000 & 10000. The meter guides your through the calibration process with on-screen instructions and hints.
Instruction Manual PCD 650 Hence calibration in % Saturation of DO should be carried out first. This is described in the following section. 3.1.6 Prepare the Meter for Calibration Before starting calibration, make sure the meter is in the appropriate measurement mode. For pH Connect the pH probe to the BNC connector of the meter. Be sure to remove the protective electrode storage bottle or rubber cap of the electrode before calibration or measurement.
Instruction Manual PCD 650 Ensure that you use new conductivity standard solutions or sachets during calibration. Do not reuse standard solutions as it may be contaminated and affect the calibration and accuracy of measurements. Use fresh calibration solution each time you calibrate your meter. Keep solutions in a dry and cool environment if possible. For DO(%) and DO (mg/L) Calibration Before starting calibration, make sure you are in the correct measurement mode and in the correct calibration sequence.

Instruction Manual PCD 650 7. APPENDIX 7.1 Conductivity theory Conductance is a quantity associated with the ability of primarily aqueous solutions to carry an electrical current, I, between two metallic electrodes when a voltage E is connected to them. Though water itself is a rather poor conductor of electricity, the presence of ions in the water increases its conductance considerably, the current being carried by the migration of the dissolved ions.
Instruction Manual PCD 650 The PCD 650 series meter not only measures conductivity readings from micro or milli Siemens but also reads resistivity (Ohms, kOhms and MOhms), TDS (ppm and ppt), and salinity (ppt). The salinity scale which ranges from 0 to 80 ppt is a measure of all salts, not just sodium chloride. This scale was originally devised for seawater, and is based on seawater at 15 degrees Centigrade has a conductivity equivalent to that of a potassium chloride solution of a known concentration.
Instruction Manual PCD 650 7.2 Calculating TDS Conversion Factor You can calibrate your meter using TDS calibration standard solutions. The calibration standard only needs to give the TDS value at a standard temperature such as 25 °C. To determine the conductivity-to-TDS conversion factor use the following formula: Factor = Actual TDS ÷ Actual Conductivity @ 25 °C Definitions: Actual TDS: Value from the solution bottle label or as a standard you make using high purity water and precisely weighed salts.
Instruction Manual PCD 650 7.4 Dissolved Oxygen Probe 7.4.1 Dissolved Oxygen Principle The probe is a galvanic measuring element which produces an output proportional to the oxygen present in the medium in which it is placed. The galvanic probe design lets you take measurements immediately – without the typical 15 minute wait of other dissolved oxygen probes. The probe consists of two parts: • An upper part consisting of an anode, a cathode, and cable.
Instruction Manual 7.4.3 PCD 650 Membrane Housing Replacement Replacement of the membrane cap housing/ membrane is required only when you cannot calibrate the probe, or if the membrane is damaged. Typical membrane damages are punctures or wrinkles caused during measurements or cleaning. Your new DO probe comes with replacement membrane housing. To order more replacement membrane housing, see the “Accessories” section page. To replace the membrane cap (with pre-installed membrane) 1.
Instruction Manual PCD 650 2. Hold the probe under hot running water and brush away the white oxide on the cylindrical anode with a stiff plastic brush – do not use metal cleaning material. 3. If the cathode has any deposits, remove them with a light scouring powder. Do not polish the cathode. 4. Using the installation tool, unscrew and remove the membrane lock from the membrane cap. See Figure 93 on the following page. 5. Remove the membrane and O-ring. Discard both. 6.
