Instruction Manual 4 4.1 CyberScan DO 110 CALIBRATION Important Information on Meter Calibration The amount of oxygen dissolved in water will depend on its temperature, atmospheric pressure and its salinity. While the pressure and salinity values are manually entered into the instrument, the temperature is being measured by the probe. It is therefore very important that the temperature is calibrated if necessary prior to the DO calibration.
Instruction Manual 4.2 CyberScan DO 110 Temperature Calibration DO in mg/L is dependent on temperature, so it is first necessary to calibrate or verify the temperature reading. The temperature sensor is part of the DO probe and the “ATC” annunciator will light up on the LCD screen once the probe is connected correctly to the meter. MEAS 98.9 22.3 83.4 MODE CAL 22.3 4. Dip the DO probe into a solution of known temperature (i.e. a temperature bath). Allow time for the temperature probe to stabilise.
Instruction Manual 4.3 CyberScan DO 110 DO Calibration (with ATC) –% Saturation Mode Dissolved Oxygen exact calibration value depends on barometric pressure. The meter is set to a factory default of 760 mm Hg, which results in a calibration value of 100% saturation in air. NOTE: If the barometric pressure setting has been changed from 760 mm Hg, the calibration value in air will automatically adjust to a value other than 100%. The adjusted value will be correct for the new barometric pressure setting.
Instruction Manual 4.4 CyberScan DO 110 DO Calibration in mg/L (ppm) Mode The amount of oxygen dissolved in a liquid will depend on its temperature, pressure and salinity. It is therefore very important to set these parameters correctly before attempting to do a calibration. Temperature is measured by the meter automatically. Pressure and salinity values are keyed in manually as described in Sections 8.8.1 and 8.8.2. MEAS READY 8.10 24.5 CAL READY 8.10 8.10 MR 8.24 8.

Instruction Manual 10 CyberScan DO 110 Dissolved Oxygen Probe 10.1 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 CyberScan DO 110 10.3 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. 10.3.1 To replace the membrane cap (with pre-installed membrane) 1.
Instruction Manual CyberScan DO 110 10.4 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. Pull off the probe guard. 1. Unscrew the membrane cap from the probe. 2.
Instruction Manual CyberScan DO 110 14. Replace probe guard. 15. Calibrate the probe (see section 4) after the % saturation readings have stabilised. 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. 10.
Instruction Manual 11 CyberScan DO 110 ERROR MESSAGES The following table provides a guideline to enable diagnosis of possible problems indicated by the messages generated by the meter. The table also provides possible solutions to the problems encountered. ERROR MESSAGE INDICATES POSSIBLE CAUSE CORRECTIVE ACTION Err. Annunciator Wrong keypad input Wrong input in selected mode. Release key. Select valid operations depending on mode.
Instruction Manual CyberScan DO 110 then there is probably moisture somewhere. See Problem 2. With membrane cap removed and probe internals thoroughly dry, the reading from the probe is not zero and/or is erratic. Moisture has entered the system – either into the probe itself or at junctions or points in the cable. This moisture creates a secondary galvanic action in addition to that produced by the probe and results in non-zero or erratic readings.
