Charging the Sensor

Connect Go Direct Optical Dissolved Oxygen to the included Micro USB

Cable and any USB device for two hours.

You can also charge up to eight Go Direct Optical Dissolved Oxygen probes

using our Go Direct Charge Station, sold separately (order code: GDX-CRG).

An LED on each Go Direct Optical Dissolved Oxygen indicates charging

status.

Oxygen

(Order Code GDX-ODO)

Go Direct Optical Dissolved Oxygen is a luminescence-based dissolved oxygen

probe that can also measure water temperature and atmospheric pressure. It is

actively temperature and pressure compensated, and there is no need for

calibration. This probe can be used in experiments to test water samples in the

field or in the laboratory.

designed nor are they recommended for any industrial, medical, or commercial

process such as life support, patient diagnosis, control of a manufacturing

process, or industrial testing of any kind.

Charging Blue LED on steady while sensor is connected to the Micro USB Cable or Charging Station. Fully charged Blue LED is off when charging is complete. 4. When you are finished making measurements, rinse the probe with distilled water. 5. Slide the lid onto the body of the probe, and then screw the lid onto the storage bottle. Channels Go Direct Optical Dissolved Oxygen has five measurement channels: Powering the Sensor Turning on the sensor Putting the sensor in sleep mode Press button once.

Calibrating the Sensor Specifications DO Concentration This channel is factory calibrated and does not require calibration by the user. If the probe is not reading accurately, a reset can be done using a one-point calibration. To do a reset 1. Fill the storage bottle to the top of the sponge with distilled water. 2. Insert the probe into the storage bottle and make sure it is positioned vertically so that the tip is not in contact with the sponge or water. 3.

The tip of the probe is a replaceable screw-on cap called the Go Direct Optical Dissolved Oxygen Replacement Cap. This cap is warranted to be free from defects of a period of two years from the date of purchase; it is possible that you can get longer use than the warranty period. If you notice a reduced response, it is probably time to replace the cap (order code GDX-ODO-CAP). To extend the lifetime of the cap, do not expose it to direct sunlight for an extended period of time.

To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. Warranty Vernier warrants this product to be free from defects in materials and workmanship for a period of five years from the date of shipment to the customer. This warranty does not cover damage to the product caused by abuse or improper use.
