3. Calibration Mode For All Meters 3.1 About Calibration The 600 series meters are factory calibrated and allows you to measure pH/mV/ion/conductivity/resistivity/TDS/salinity/DO(%)/DO(mg/L) respective to the model(s) you have purchased. Calibrate to all measurement ranges to ensure the highest accuracy in any given measurement range.
It is recommended that you perform at least a 2-Point Calibration using standard buffers that adequately cover the expected measurement range, prior to measurement. For Ion Connect the ISE to the BNC connector of the meter. Remove plastic protective cap of ISE. Briefly rinse the electrode with clean water to remove any residues. Rinse ISE before and after each calibration or sample measurement to avoid cross-contamination. Ensure that you use new or fresh standard solutions during calibration.
All new calibration values will automatically override the existing data. It is recommended to calibrate the meter periodically and or if it is suspected to be inaccurate. Always rinse the probe with either DI water or rinse solution before and after each calibration/sample measurement. When calibrating in air, make sure that any water droplets from the probe’s membrane are removed. 3.4 Accessing Calibration mode From measurement mode, press CAL (F2) key.

PART A - % Saturation Mode 1. O2 % - DO Saturation Setup The DO saturation (%) setup screen presents many options to control the operating parameters, which can be controlled and set from the DO setup screen. The settings are displayed in 2 pages. Press NEXT-P (F2) and PREVP (F1) to navigate through these pages.
DO (%) Settings Page 2 – Hi-Lo Set Points Figure 50: DO (%) Settings Page 2 – Hi-Lo Set Points This page allows you to set alarm limits for the DO saturation measurement mode. A visual alarm symbol will appear on the screen, if the DO value of the measurement is outside of the boundaries set by the minimum and maximum limits.
2. DO Calibration in % Saturation Mode (with ATC) 2.1 About DO(%) and DO (mg/L) Calibration The calibration of % Saturation of DO will linearly affect the measurement for DO in mg/L. The amount of oxygen dissolved in water will depend on its temperature, atmospheric pressure and its salinity. It is therefore very important that the temperature is calibrated if necessary prior to the DO calibration. Hence calibration in % Saturation of DO should be carried out first.
Figure 51: Saturation Calibration Screens 4. Rinse the probe well with de-ionized water. For best results, blot the end of the probe to dry it. Do not touch the membrane. 5. The meter then shows saturation calibration screen. The primary display will show the current value of measurement. Wait for the reading to stabilize. 6. Press ENTER key to confirm the calibration. The meter automatically calibrates to 100% air saturation and returns to the measurement mode.

Press MODE key to select % Saturation mode. 2. Immerse the DO probe in 0% solution. Stir gently to create a homogenous solution. 3.
2.3.1 % DO Calibration Report Calibration report gives you detailed information for the % saturation. It includes date & time, 0% and 100% saturation mV value, % saturation offset calibration and barometric pressure at which the solution was measured. 2.3.2 To View Calibration Report: 1. From % saturation measurement mode, press left or right arrow key to navigate to other available functions until you see REPO function in the LCD. 2. Press REPO (F2) key. The calibration report is shown in the display. 3.
2.5 Set barometer pressure range and barometric pressure units The PCD 650 meter is capable of measuring barometric pressure with its built-in pressure sensor. In the event that the pressure reading is inaccurate, you can calibrate the value from the setup menu. 2.6 Pressure compensation If pressure comp. is set to ‘ENABLE’, the meter will compensate for the barometric pressure at the location depending on the altitude.

PART B – Concentration (mg/L) (ppm) Mode 1. O2 mg/L (ppm) – DO Concentration Setup DO Concentration (mg/L) setup screen present many options to control the operating parameters, which can be controlled and set from the DO setup screen. The settings are displayed in 2 pages. Press NEXT-P (F2) and PREVP (F1) to navigate through these pages.
DO (mg/L) – Page 2 Figure 57: DO (mg/L) – Page 2 This page allows you to set alarm limits for the DO concentration mode. A visual alarm symbol will appear on the screen, if the DO value of the measurement is outside of the boundaries set by the minimum and maximum limits.
2. DO Calibration in mg/L mode or ppm Concentration mode The amount of oxygen dissolved in a liquid will depend on its temperature, atmospheric pressure and salinity. It is therefore very important to set temperature and salinity correctly before attempting to do a calibration. The meter is capable of measuring barometric pressure with its built-in pressure sensor. In the event, the pressure reading is inaccurate, you can calibrate the value from the Setup menu. 1. Switch the meter on.
7. Press ENTER key to confirm the entered value. 8. Press ESC (F4) to go to measurement mode. The meter shows the concentration reading of the solution in measurement mode.

pressure/oxygen concentration relationship of your sample. The salinity can be set from 0 to 50 ppt. 2.2.1 Auto Salinity Compensation If auto salinity comp. is enabled, the meter will automatically compensate for salinity for determining dissolved oxygen concentration of the sample. Auto salinity compensation will be applicable only in multi measurement mode and only if one of the measurement selected is conductivity related. This option is activated only in CD650 & PCD650.

Since any deposits on the membrane surface act as a barrier to oxygen diffusing through the membrane, the membrane must be cleaned at regular intervals to assure maximum reliability. After using the probe, rinse the probe in clean water and wipe it with a soft cloth or paper to avoid any hardening of deposits. If growth develops on the probe, use a disinfecting chemical to clean. NOTE: Although the membrane is strong and not easily damaged, wipe it gently while cleaning it.
To replace the membrane cap (with pre-installed membrane) 1. Replacement is much easier with single membrane housing. Unscrew the old membrane cap housing. 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.
3.2.4 Membrane/O-ring Replacement (Optional Procedure) It is recommended only experienced service personnel can perform this procedure. This procedure is OPTIONAL, and should only be performed if you have new membrane and O-ring. You are also required to have a membrane installation tool. These items are available as optional accessories in the “Accessories” section. 1. Pull off the probe guard. 2. Unscrew the membrane cap from the probe. 3.
Note: Membranes can only be used once. When a membrane cap is screwed onto the probe, the membrane is stretched by the cathode. If the same O-ring and the membrane is used a second time it will not fit perfectly onto the cathode. This will result in erratic readings. 3.2.5 Electrolyte Solution The electrolyte solution in your probe’s cap will deplete on usage and will need to be replaced periodically. Your new DO probe comes with accessories of one replacement electrolyte solution and a spare membrane cap.
