Any other use, or use not mentioned here, that is incompatible with the technical specifications is deemed inappropriate. The operator is solely responsible for any damage arising from such use.
2. PRODUCT DESCRIPTION 2.1 Drinking Water Turbidity The LaMotte 2020 ClearTrace Inline Turbidity System continuously monitors low-range turbidity and temperature in drinking water applications. In the standard system configuration, data is reported through a local display and a scalable 4 – 20 milliamp current output. All functions can be accessed through a digital network with or without the local display interface.

3. MOUNTING, WIRING AND PLUMBING Figure 3.1: Wall mounting Clearances 3.1 Mounting The 2020 ClearTrace Turbidity System is mounted on a 12 inch x 12 inch panel with four ¼ inch mounting holes. Use ¼ inch bolts with washers to mount the panel to a wall. Make sure the sample chamber is level and plumb to insure proper water levels are maintained in the sample chamber. It is important to note that the system must be fixed securely to the wall to insure the chamber does not move when handled or touched.
5. Rotate the Turbidity System out of the way and drill the other three mounting holes. 6. Place all four bolts with washers and tighten. Use shims if necessary to insure the sample chamber is level. 3.2 Plumbing The Turbidity System has an INLET, an OUTLET and a DRAIN. Barb fittings are provided for the INLET and OUTLET in the event that 3/8 inch ID tubing is used. When piping is used instead of tubing, remove the barb fittings to install ¼ inch NPT threaded pipe for the INLET, OUTLET and DRAIN.
3.4 Wiring For 24 VDC and 110 VAC Power Access to all User wiring is through the ¼ DIN junction box in the lower left on the mounting panel. The standard on-line turbidimeter requires 24 VDC for power and typically draws 270 mA (6.5 watts) or optionally requires 100-240 VAC at 50/60 Hz for power and typically draws up to 250 mA (10 watts).

3.6 Sample Chamber Details The sample chamber is designed for easy access and maintenance. The chamber lid is lifted to gain access to the sample chamber. Set it on top of the AV38 during chamber maintenance. When replacing the lid, it should be aligned using the exterior alignment markers on the front edge of the chamber and the lid.
4. MEASURE SCREEN OVERVIEW 0.035 NTU AB The AV38 user interface is 30.8 °C DS1: 6 shown in Figure 3.1. It consists of an LCD module that contains two lines of 16 MENU ESC ENTER alphanumeric characters and t seven keys to navigate the menu. The contrast of the Figure 3.1: The elements of the measure screen LCD module can be adjusted by simultaneously pressing the escape and up-arrow keys (for more contrast) or the escape and down-arrow keys (for less contrast).
5. MENU STRUCTURE Pressing the menu key while a measure screen is displayed accesses the main menu. The items in the main menu are the same regardless of the type of sensor head that is installed in the DataStick. Table 4.1 shows all accessible functions including optional features. Note: Not all optional features are currently available on 2020 ClearTrace System.

6. CALIBRATION NOTE: The unit should be on for 30 minutes to allow the lamp to warm up before begining calibrations or taking measurements. Drain Chamber, Shut off Inlet 6.1. Span Calibration To calibrate the span for the Turbidity System: 1. Drain the sample chamber. 2. Shut off flow to the sample chamber. Drain and Inlet are shut off: 3. Remove the chamber lid and place it Ready to calibrate on top of the AV38. 4. Rinse the chamber with clean water and then with a small amount of calibration solution.
