Page 4: Introduction
“may” agree with each other in a relative sense, but this is not always a guarantee. The HM-500 Series is designed to be calibrated to agree with the oil-in- water concentration from a given oil type determined by commonly used methods. The calibration of the HM-500 Series probe should be initially done by the user with an actual prepared oil-in-water standard, within the detection range of the sensor itself. -

Net Weight 510 10 g Pyxis OIW-500 is a synthetic standard which will read 500 ppm by a factory calibrated HM-510 probe. This product must be diluted for use with HM-500 and HM-520 inline probes to measure within their range. Once the HM-500 Series probe is calibrated to a known oil-in-water standard, you may use the equivalent value of the prepared oil- in-water secondary standard for future sensor calibrations. -

For the first calibration, it is required to prepare an oil-in-water calibration solution using the desired oil with a concentration within the range of the HM-500 Series probe being used (i.e. HM-500 should be calibrated with a user-prepared, oil-in-water solution between 1 and 10 ppm). The user-prepared, oil-in- water calibration solution can be made by mixing a sample of the oil with DI water to develop a known ppm level. -

Clean message will be shown (Figure 12). If the probe is partially fouled, a yel- low Becoming Dirty message will be shown. If the probe is severely fouled, a red Dirty message will be shown. In this case, follow the procedure in the Methods to Cleaning the HM-500 Series Probe section of this manual. -

6 Setup and Calibration with uPyxis® Desktop App The HM-500 Series probe should be initially calibrated with a two-point (zero + slope) procedure using a deionized (DI) water sample (zero) and a prepared solution (slope) containing the actual oil-in-water de- sired. -

Clean message will be shown (Figure 19). If the probe is partially fouled, a yellow Becoming Dirty message will be shown. If the probe is severely fouled, a red Dirty message will be shown. In this case, follow the procedure in the Methods to Cleaning the HM-500 Series Probe section of this manual. -

Figure 19. 7 Communication using Modbus RTU The HM-500 Series is configured as a Modbus slave device. In addition to the ppm oil-in-water value, many operational parameters including warning and error messages are available via a Modbus RTU connection. Contact Pyxis Lab Technical Service (service@pyxis-lab.com) for more information. -
Page 19: Sensor Maintenance And Precaution
To clean the HM-500 Series probe, soak the lower half of the probe in 100 mL of the prepared cleaning solution for 10 minutes and gently scrub the quartz optical sensor channel. Rinse the HM-500 Series probe with distilled water and then check for the flashing blue light inside the HM-500 Series probe quartz tube. -

Series probe from direct sunlight and precipitation. 9 Troubleshooting If the HM-500 Series probe output signal is not stable and fluctuates significantly, make an additional ground connection—connect the clear (shield, earth ground) wire to a conductor that contacts the sample water electrically such as a metal pipe adjacent to the HM-500 Series tee.
