If you use automatic water-sampling equipment, consider performing a maintenance check-up during the month of August, which is National Water Quality Month in the U.S. When you perform a maintenance check-up, you can help ensure that your equipment is operating at an optimal level and that you are acquiring accurate water-quality data.
The need to clean and maintain your Campbell Scientific water-sampling equipment varies depending on the sampler model you are using, as well as the fluid you are sampling and testing. That being said, there are some general maintenance suggestions that you can follow for any of our automatic water samplers:
In addition to performing a general maintenance check-up of your water-sampling equipment, it’s always a good idea to make sure the internal backup battery of the water-sampler controller is working correctly. How long the controller’s internal backup battery lasts depends on how long it remains in disuse, how long it is in use, and the complexity of the running program.
A 3.0 Vdc coin-cell battery (pn 15598) and
a 3.6 Vdc 1/2 AA size cell battery (pn 13519).
For the internal battery, Campbell Scientific water samplers commonly use either a 3.0 Vdc coin-cell battery (pn 15598) or a 3.6 Vdc 1/2 AA size cell battery (pn 13519). Typically, your internal battery should provide several years of continued service. For example, under normal operating conditions and temperatures, the 15598 coin-cell battery (used in the PVS5120C and PVS5120D water samplers) has an estimated five-year life expectancy.
So, how would you know that it's time to change the internal battery? You might suspect that the internal battery is failing if any of these conditions are met:
When you replace the internal 3.6 Vdc 1/2 AA size cell battery (pn 13519) in the 16-touch keypad controller, follow these steps to keep the new battery from discharging:
To replace the 3.6 Vdc 1/2 AA size cell battery, you will need to remove the four screws in the cover of the controller. Carefully lift the lid back so that the connecting cable does not become torn. With the lid in the lifted position, the battery is visible and easily accessible for replacement.
To replace the 3.0 Vdc coin-cell battery (pn 15598), refer to the instruction manual of the PVS5120-series water sampler. Alternatively, call Campbell Scientific for assistance.
Recommended for You: For more detailed maintenance information, including information about replacing an internal battery, refer to your automatic water sampler’s instruction manual. |
Thank you for doing your part—whether in August or some other time of the year—to monitor the quality of our water resources and help minimize the negative impact of neglect, pollution, and overuse.
