This meter is a microprocessorbased instrument that is designed to be handy, user-friendly and capable of allowing one-hand operation. It has a large customized LCD for clear and easy reading. It also has user-friendly features, all of which are accessible through the membrane keypad. It is a unique and intelligent instrument that has capability to cater to the preferences of the discerning individual. You have one of three models: · · · CON 10 meter: CON 100 meter: CON 200 meter Your meter includes a conductivity electrode (cell constant K = 1.0) with built-in temperature sensor (Order Code: EC-CONSEN41B for CON 10, EC-CONSEN21B for CON 100/200), and batteries. Please read this manual thoroughly before operating your meter. 1 2 2.1 DISPLAY AND KEYPAD FUNCTIONS Display The LCD has a primary and secondary display. The primary display shows the measured conductivity or TDS reading. The secondary display shows the measured temperature.

Some buttons have several functions depending on its mode of operation. Key ON/OFF Function 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. For example, if you shut the meter off in TDS measurement mode (only in CON 10 & CON 200 meters), the meter will be in TDS measurement mode when you switch the meter on. Freezes the measured reading. To activate, press HOLD while in measurement mode. To release, press HOLD again. Selects the measurement parameter. ~ CON 10 meter: Toggles between conductivity, TDS and temperature. ~ CON 100 meter: Toggles between conductivity and temperature. ~ CON 200 meter: Toggles between conductivity, TDS and temperature. Toggles between Calibration and Measurement mode. NOTE: Temperature calibration is available from conductivity calibration mode; see section 4.3 for directions. ENTER function: Press to confirm values in Calibration mode and to confirm selections in SETUP mode. RANGE function: Press to enter manual ranging function. The MEAS indicator blinks while in manual ranging function. In Measurement mode: ! Press MI/! (memory input) to store values with its corresponding temperature values in the memory. Press MR (memory recall) to retrieve data from memory. In Calibration mode: Press to scroll through calibration values. In SETUP mode: Press to scroll through the setup subgroup programs. Takes you into the SETUP mode. This mode lets you customize meter preference and defaults, and view calibration, electrode offset data and select cell constant. Sends the displayed data through the RS 232C connector to the peripheral device (computer or printer). HOLD MODE CAL/MEAS ENTER / RANGE MI/! & MR/" !

Inserting the Batteries Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure 3 below. Lift meter stand to expose battery cover. Remove battery cover. Insert batteries. Follow the diagram inside the cover for correct polarity. Replace the battery cover into its original position using the two screws removed earlier. Four AAA batteries are included with your meter. Remove Screws Figure 3: Back panel of meter showing battery compartment 5 To connect the Conductivity/TDS electrode with built-in temperature sensor: a) During this operation, it is important that water does not get onto the BNC connector. Also avoid touching the connector with soiled hands. Slide the electrode connector of electrode over the socket of the meter (BNC connector). Ensure that the slot of the connector is inline with the protrusions of the socket. Rotate the connector clockwise until it locks. Be careful not to use excessive force in this operation. Figure 4: Connecting the Conductivity /TDS probe b) The built-in temperature probe uses a phono jack to connect with the socket on the meter. Insert the jack into the socket as shown in Figure 5. Figure 5: Connecting the built-in temperature sensor 6 3.2 Attaching the electrode holder onto the meter The meter has a slot on the side for the attachment of the electrode via the electrode holder. a) The meter provides a slot on the side of the instrument for the electrode holder. Hold the electrode holder over the slot of the meter. Ensure the flange of the electrode holder is facing the slot. Note the orientation to make sure that it is the orientation that you desire (see figure below). b) Gently slide the flange of the electrode holder into the slot. Ensure that the electrode holder is fixed properly into the slot. Figure 6: Attaching the electrode holder to the meter Figure 7: Sliding the electrode holder into the slot 3.2.1 Special Features The electrode holder can be attached in different positions (multi-position) as shown. This allows you the flexibility in measurement and storage. Figure 8: Multi-position of the electrode holder 7 3.3 Attaching the electrode onto the electrode holder Your meter comes complete with an electrode holder. It is designed for easy use and installation. Care must always be taken to avoid use of excessive force in the process of attaching these components. a) Align the end of the electrode (sensor side) with the hole of the holder. Note that the top side of the holder is where the slot begins. b) Always ensure that the diameter of the electrode you intend to use is 12 mm. Otherwise, the electrode may not fit properly. c) Insert the electrode into the hole of the holder until the top housing of electrode touches the top of the holder. Remember not to force the electrode into the holder. 3.4 Connecting the A.C. adapter The CyberScan CON 10/100/200 meter has the flexibility of operating from an A.C. power source. This is extremely useful if you have an A.C. source available near the meter (e.g. Laboratory). 1. Before plugging in the A.C. adapter, switch off the meter and the power source of the A.C. adapter. This is a safety precaution that should be adhered to safeguard your meter. 2. The A.C. adapter should have the following settings: Output Voltage: 9 V D.C. Current: 500 mA NOTE: Ensure that the input mains voltage (110/220/240 V) matches your adapter requirements. 3. 4. Insert the D.C. jack into the socket of the meter as shown in Figure 9. Switch on the power to the adapter, followed by the meter. 8 Figure 9: Inserting the A.C. power adapter 3.5 Connecting the RS 232C cable (only for CyberScan CON 200) The CyberScan Conductivity CON 200 meter provides an RS 232C output for you to transmit the reading either to a printer or a computer. This is extremely useful in instances where the meter is used for continuous monitoring of a certain process or experiment. The data output to the printer or computer can be then evaluated. The data is output in the ASCII format. This format allows the data to be imported by a wide variety of software that read ASCII data (e.g. LOTUS 123 C, Microsoft Excel, etc.). Eutech Instruments also provides software that can capture the data transmitted into an ASCII file for later use. a) Open the communication port cover located at the bottom of the meter as shown in Figure 10. Do not use excessive force when doing this. b) Noting the orientation of the RS 232C connector, plug the RS 232C male connector into the RS 232C port of the meter. c) Fasten the connector by fastening the two screws at the side of the male connector. 9 Location of RS 232 port Figure 10: The CyberScan CON 200 RS 232 port 3.5.1 RS 232C Configuration The CyberScan CON 200 meter has a 9-pin female RS 232C connector with the following pinout: PIN NO 1 2 3 4 5 6 7 8 9 DESCRIPTION Transmit Data DSR (Data Set Ready) GND CTS (Clear to Send) - A one-is-to-one connection can be made with a 9-pin RS 232C port of the computer. In case the meter output has to be sent to a 25-pin RS 232C connector, the following cable configuration may be used: 10 CyberScan CON 200 25-pin connector 2 (TxD) --------------------------------------- (RxD) 3 4 (DSR) -------------------------------------- (DTR) 20 5 (GND) -------------------------------------- (GND) 7 7 (CTS) --------------------------------------- (RTS) 4 Refer to Figure 11 for the pin number position. 5 4 3 2 1 9 8 7 6 Figure 11: Pin number position of the 9-pin RS 232 port The meter uses hardware handshake i.e. the meter expects both DSR and CTS lines to be active before it sends data. If the key is pressed while the printer is not ready or if the printer is off, the meter d ...
