Page 7: Use Of Hazard Information
2.2. Use of hazard information DANGER Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death or serious injury. WARNING Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death or serious injury. CAUTION Indicates a potentially hazardous situation that may result in minor or moderate injury. -
Page 8: Wiring And Handling Precautions
NOTICE Delicate internal electronic components can be damaged by static electricity, resulting in indeterminate instrument performance or eventual failure. Smart Storm recommends taking the following steps to prevent ESD damage to your instrument: • Before touching any instrument electronic components (such as printed circuit cards and the components on them) discharge static electricity from your body. -
Page 9: Turning On The Environmental Usm
The instrument is designed to read a range of environmental measurements associated with the wastewater industry with an optional on-board data logger for recording and downloading to the Smart Storm Inquisitor data viewing platform. Three relays (with LED indication) and two 4-20mA outputs are provided to control ancillary equipment and the meter can be interrogated remotely using Modbus RTU (RS485) communication. - Page 10 ➢ CONN6 - bottom row provides the RS485 connections for the connection of a digital probe. The power connections for the probes are also available. ➢ CONN7 – provides the connection for the ISE probe including a PT100 temperature input and a connection for grounded probes.

Page 18: What Is Cod
If the COD is too high, then the receiving waters can be stripped of their oxygen levels and damage aquatic life. The figure below shows the correlation of UV254 absorption and COD as measured with the smart storm UV254 probe. COD Measurements COD mg/L Figure 4-7 COD diagram measurements. -
Page 19: Cod Calibration
4.3.2. COD Calibration. • Been in the DIGITAL PROBE settings as below, scroll down to “PROBE CALIBRATION” and validate with the follow key icon Use the key to scroll down to the probe calibration option and validate your button. Scroll down to UVA – Parameters to calibrate selection using the COD/BOD/TOC/DOC. - Page 20 First select the high point by using the button. Now enter you value by using the buttons and validate your input to start the high point calibration process with your probe into the COD solution. This is where the maximum concentration is stored. After the completion of the high point calibration, restart the above step again but with the low point calibration option to enable two points calibration.
- Page 21 The main advantage the UV254 surrogate measurement has over the above is speed of measurement. The Smart Storm online UV254 can take an input from these analysers, allowing the combine system to provide real time calibrated measurements. The calibration procedure on the USM is the same as the COD calibration on the previous page.

Page 22: Digital Probe Calibration
The main advantage the UV254 surrogate measurement has over the above is speed of measurement and operational cost. The Smart Storm online UV254 can be purchased with a filter before the flow cell to remove the suspended organic material, and allow for better surrogate measurements of DOC. - Page 23 Figure 4-8 Probe Calibration Mode Select the parameter your reading before making any modification. Use the Up and Down key to browse the selection. Figure 4-9 Gain Correction Probe Selection From the screen below, use the up and down keys to enter the value for option.
