Page 6: Introduction
Instruction Manual CyberScan DO 110 INTRODUCTION Thank you for selecting the DO 110 meter. These meters are microprocessor-based instruments and are designed to be handy, capable of allowing one-hand operation. It is capable of measuring Dissolved Oxygen (DO) in mg/L or ppm units, % saturation and temperature. -
Page 7: Display & Keypad Functions
Instruction Manual CyberScan DO 110 DISPLAY & KEYPAD FUNCTIONS Display The LCD has a primary and secondary display. • The primary display shows the measured % Saturation or mg/L (or ppm) values. • The secondary display shows the measured temperature. The display also shows error messages, keypad functions and program functions. -
Page 8: Keypad
Instruction Manual CyberScan DO 110 Keypad A large membrane keypad makes the instrument easy to use. Some buttons have several functions depending on its mode of operation. FUNCTION • ON/OFF - Powers on and shuts off the meter. The meter will start in a measurement mode similar to the last measurement mode it is in before being switched off. -
Page 9: Preparation
Instruction Manual CyberScan DO 110 PREPARATION Inserting the Batteries This meter is packaged with 4 “AAA” alkaline batteries required for operation. To insert the batteries into the meter, follow the procedure outlined below. 1. To open the battery compartment, press down the catch of the battery cover. See below. - Page 10 Instruction Manual CyberScan DO 110 NOTE: Do not substitute other probes or electrodes. For replacement probe, see the “Accessories” section. Keep connector dry and clean. Do not touch connector with soiled hands. 1. Line up the notch and 6 pins on the meter with the holes in the 6 pin connector.

Page 11: Connecting The Ac/Dc Adapter
Instruction Manual CyberScan DO 110 Connecting the AC/DC Adapter Besides using four AAA-sized batteries as a power source, the DO 110 meter can also operate from the power mains using an AC/DC power adapter. This is extremely useful if you have an A.C. power source available (e.g. laboratory). Before plugging in, switch off the meter and the power source of adapter. -
Page 12: Rs232C Configuration
Instruction Manual CyberScan DO 110 RS232C Configuration 3.4.1 The DO 110 meter has a 9 pin female RS232C connector with the following pin out: PIN NO. DESCRIPTION Transmit Data CTS (Clear to Send) GND (Ground) A one-to-one connection can be made with a 9 pin RS232C port of the computer. In case DO 110 meter’s output has to be sent to a 25 pin RS232C connector, the following cable configuration may be used: DO 110... -
Page 13: Calibration
Instruction Manual 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. -
Page 14: Temperature Calibration
Instruction Manual CyberScan DO 110 Temperature Calibration DO in mg/L is dependent on temperature, so it is first MEAS 98.9 necessary to calibrate or verify the temperature reading. The temperature sensor is part of the DO probe and the “ATC” °C 2 2 . -
Page 15: Do Calibration (With Atc) -% Saturation Mode
Instruction Manual 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 MEAS 83.4... -
Page 16: Do Calibration In Mg/L (Ppm) Mode
Instruction Manual CyberScan DO 110 DO Calibration in mg/L (ppm) Mode MEAS The amount of oxygen dissolved in a liquid will depend on its READY 8.10 temperature, pressure and salinity. It is therefore very important mg/l to set these parameters correctly before attempting to do a °C 2 4 . -
Page 17: Measurement
Instruction Manual CyberScan DO 110 MEASUREMENT During measurement, care must be taken not to allow the membrane of the DO probe touch any surface. The probe can either be fully or partially immersed in the solution. The READY indicator appears on the display when the readings stabilize. It will turn off if the readings start to fluctuate. -
Page 18: Taking Measurements
Instruction Manual CyberScan DO 110 Taking Measurements 1. Rinse the probe with deionised or distilled water before use to remove any impurities adhering to the probe body. If it is dehydrated, soak it for 30 minutes in tap water. 2. Switch on the meter. The MEAS annunciator appears on the top of the LCD. -
Page 19: Memory Function
Instruction Manual CyberScan DO 110 MEMORY FUNCTION The DO 110 meter can store up to 100 sets of data. You can store data in any combination of values such as “% Saturation and temperature” or “mg/L (or ppm) and temperature”. MEAS Memory Input 98.9... -
Page 20: Print Function
5. Turn on DO 110 meter and note the following: a. For printer, ensure it is powered on and paper is loaded. b. For computer, ensure that Eutech Instruments’ CyberComm Portable Data Acquisition Software is installed and activated. See section 9.3 - on page 41.
