Page 5: Introduction
INTRODUCTION Thank you for selecting an Alpha COND 500 2-Wire 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 6: Preparation
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 7: Power Supply Requirements (Sl2 Position)
Power Supply Requirements (SL2 Position) The Alpha COND 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 8 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 13: Calibration
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 14 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 60.0 to 170.0 mS To view current calibration point, see Section 6.8 - Viewing Calibration .

Page 15: Temperature Calibration
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 16: Conductivity Calibration
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 17: Advanced Setup Functions
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 COND 500 transmitter provides six selections of conductivity measurement ranges to suit your process application needs. - Page 18 For zooming setting, use the ▲ or ▼ keys to set SETUP 0.00 the conductivity low zoom value for the 4 mA μS HOLD current and press the ENT key to confirm. The transmitter now displays the high zoom value setup.

Page 19: Temperature Compensation Setting
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 20 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: Temperature Coefficient And Normalization Temperature Setting
Temperature Coefficient and Normalization Temperature Setting Since different process liquid may require different temperature coefficient factor for its temperature compensation calculation, COND 500 transmitter allows 0 to 10% temperature coefficient factor adjustment to cater for your different application needs. You also have the selection of 25.0 °C or 20.0°C for the conductivity measurement normalization temperature. -
Page 24: Cell Constant Setting
Cell Constant Setting You can select up to three types of cell constant in the setup mode: - K=1.0, K=0.1 or K=10. From the measurement mode, SETUP Press the ENT key to enter the setup mode. Use HOLD the ▲ or ▼ keys to scroll till LCD displays ‘SEt’ in the upper display;... -
