Page 7: Introduction
Instruction Manual CON 500 INTRODUCTION Thank you for selecting a CON 500 LCD Transmitter. This isolated output 4-20mA transmitter is a sturdy microprocessor-based instrument that measures conductivity and temperature and transmits its output via the 2-wire power supply loop. This transmitter has many user-friendly features – all of which are completely accessible through the water-resistant membrane keypad. -
Page 8: Preparation
Instruction Manual CON 500 PREPARATION Remove screws from the four corners at the back of the Transmitter, and remove back cover. Connectors should be exposed as follows: Figure 1 – Connection Guide All wiring is done on 2 detachable connectors: – 9-pin connector (located on SL1 position) for Conductivity electrode and temperature sensor;... -
Page 9: Power Supply
Instruction Manual CON 500 Power Supply Requirements (SL2 Position) The CON 500 transmitter requires a 12 to 24V DC power supply. Other Transmitters and/or a chart recorder may be connected in the loop. Insert positive loop wire from power supply to pin 1, tighten screw. Insert negative loop wire to pin 2, tighten screw. -
Page 10: To Connect Atc Temperature Sensor
Instruction Manual CON 500 2.2.2 To connect ATC temperature sensor: For Automatic Temperature Compensated (ATC) Conductivity readings, an in-built temperature sensor is usually integrated in the industrial conductivity electrodes. Otherwise, a separate 100Ω Pt RTD temperature probe can be used. 3 wire temperature sensor Insert the Pt100 input wire to pin 5 of SL1 connector. -

Page 15: Calibration
Instruction Manual CON 500 CALIBRATION Important Information on Transmitter Calibration Calibration should be carried when you are using your transmitter with a new electrode for the first time or when you suspect that the transmitter/electrode is out of calibration. Your transmitter allows you to perform temperature calibration and conductivity calibration. - Page 16 Instruction Manual CON 500 Table 1 Conductivity Recommended Calibration Solution Measuring Range Range 19.99 µS 6.00 to 17.00 µS 0.00 199.9 µS 60.0 to 170.0 µS 1999 µS 600 to 1700 µS 0.00 10.00 mS 6.00 to 7.00 mS 0.00 19.99 mS 6.00 to 17.00 mS 199.9 mS...

Page 17: Temperature Calibration
Instruction Manual CON 500 Temperature Calibration You need to perform temperature calibration if your transmitter temperature reading is inaccurate or if the transmitter’s cell constant setting is changed. It is because the transmitter’s temperature offset calibration will be erased once a new cell constant is selected. -
Page 18: Conductivity Calibration
Instruction Manual CON 500 Conductivity Calibration MEAS A 1-point Calibration is required for this transmitter. If 1578 µS the calibration process is aborted, your transmitter will revert to the previous calibration data. °C Organize your calibration standard solution 25.5 in two beakers – one for rinsing and the other for calibration. -
Page 19: Advanced Setup Functions
Instruction Manual CON 500 ADVANCED SETUP FUNCTIONS The advanced setup mode lets you customize your transmitter’s preferences and defaults. This transmitter features different sub groups that organize all setup parameters. The sub-groups are: Range and Zooming Selection Setting Your CON 500 transmitter provides six selections of conductivity measurement ranges to suit your process application needs. - Page 20 Instruction Manual CON 500 For zooming setting, use the ▲ or ▼ keys to set SETUP the conductivity low zoom value for the 4 mA 0.00 µS HOLD current and press the ENT key to confirm. The transmitter now displays the high zoom value setup.

Page 21: Temperature Compensation Setting
Instruction Manual CON 500 Temperature Compensation Setting Conductivity readings are affected by temperature. Under varying temperature conditions, use ATC to compensate for the conductivity values. If temperature of sample is constant, and a temperature sensor/probe is not available, Manual Temperature Compensation can be utilized. 6.2.1 Automatic Temperature Compensation For automatic temperature compensation (ATC) selection, connect the ATC sensor... -
Page 22: Manual Temperature Compensation
Instruction Manual CON 500 6.2.2 Manual Temperature Compensation For manual temperature compensation you can set the process and calibration temperatures. This allows calibration at a temperature other than the process temperature. Example: setting a calibration temperature of 25°C lets you calibrate using standard solutions at 25°C, even if your process temperature is different from 25°C. - Page 23 Instruction Manual CON 500 SETUP HOLD SETUP SETUP HOLD HOLD SETUP SETUP HOLD HOLD °C SETUP HOLD Temperature Compensation Setting Chart – alpha CON 500 Transmitter - 17 -...
