List of accessories and introduction to their main functions

Introduction to each component inside the box

1. Chassis: Contains the host (data logger), as well as the battery and connecting wires. The wire part of the equipment has been fixed and integrated for installation, and the body itself is made of plastic material. Therefore, when removing it, be careful not to touch or drop it, otherwise it may cause damage to the equipment!

The chassis itself adopts waterproof design, so try to avoid immersion in liquids as much as possible. In addition, the probe interface exposed from the chassis does not have waterproof function without connecting cables. Pay more attention when using it.

2. Probe: The probe model shown in the picture is FL24, which is a groundwater probe with a working depth of less than 70M.

3. CD (USB flash drive for some instrument configurations)

4. Cable (FL24 cable has one end connected to the probe)

5. USB connection cable

6. Wash the brush

7. Hexagonal tool

8. Sample injection interface

9. Battery

Connect the host and probe:

There is a protruding opening on one side of the chassis box, with an extended interface. On the interface section, you will see an 8-hole terminal post with a red dot at the upper end of the outer wall of the port. Take out the cable and remove the metal cap on the end with the metal cap. Align the red dot on the port of the cable with the red dot on the interface and insert it completely. After inserting, you will hear a "click" sound.

After completing the above steps, the host and probe are connected.

The completed effect should be as shown in the following figure

When the probe is not suitable, use a brush to clean the inside of the probe to avoid tracer adsorption on the light-emitting tube, which may affect the next use. Each time the probe is used, it also needs to be cleaned with a brush before use.

After connecting the CR850 data collector, the data can be viewed through the collector's display screen

Press Enter to enter, then select data, press Enter, then select Real time Tables and press Enter, select Test and press Enter to view the measurement data. The Esc button is a up, down, left, and right movement button marked with up, down, left, and right arrows that returns to the upper menu.

When the battery level is low, remove the green sheet power supply head of the CR850 collector to charge the battery.

Please refer to the CR850 documentation of LoggerNet4.0 for the method of reading data by connecting to a computer. The LoggerNet4.0 software and USB driver need to be installed.

This system is set with three collection times and data storage times at the factory, namely 300S, 600S, and 900S. The 300S collection interval can store data for about 500 days, the 600S collection interval can store data for about 1000 days, and the 900S collection interval can store data for about 1500 days. Before the data is fully stored, it must be read out. The shorter the collection time, the greater the power consumption, and the shorter the storage days. The system defaults to collecting data once every 900S when it leaves the factory.

When not in use, unplug the power supply green sheet of CR850. When in use, simply plug in the sheet to make the instrument work. Ensure that the battery is fully charged before each outdoor trip.
