Automatic Water Sampler Maintenance Tips

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.

General Maintenance

清洁和维护坎贝尔科学水采样设备的需要取决于您使用的采样器型号，以及您正在采样和测试的流体。话虽如此，有一些一般的维护建议您可以随时随地遵循我们的任何自动采样器:

1. After collecting the samples and emptying the sample containers, thoroughly clean the sample containers.
2. 常规检查所有管道是否没有裂缝或分裂。
3. Replace any parts that are worn.
4. Replace the tubing if algae or bacterial growth is suspected.
5. Clean the metering chamber and conductivity rod routinely.
6. 检查样品容器中的水样卷是否正确。该体积由仪表室设置控制。（重大方差需要进一步调查。）
7. Using the controller, ensure that all of the samples have been collected as programmed. (Missing samples would require further investigation.)
8. To enable continuous sampling, remove the filled sample containers, and replace them with sanitized, empty sample containers.

Maintenance of the Internal Battery

除了执行水采样设备的一般维护检查外，还可以确保水采样器控制器的内部备用电池正常工作。控制器的内部备份电池持续多长时间依赖于废物中仍然存在多长时间，使用多长时间，以及运行程序的复杂性。

a 3.6 Vdc 1/2 AA size cell battery (pn 13519).

For the internal battery,坎贝尔科学水采样器通常使用3.0 VDC硬币电池（pn 15598）或3.6 VDC 1/2 AA尺寸电池电池（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 thePVS5120C和PVS5120D水采样器）估计为期五年的预期寿命。

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:

• The charge is down considerably (for example, down to 2.9 Vdc for a 3.6 Vdc battery).
• The sampler clock has drifted outside of the specifications.
• You notice that your entered programs are not being stored in memory.

3.6 VDC 1/2 AA尺寸电池电量

When you replace the internal 3.6 Vdc 1/2 AA size cell battery(pn 13519)in the 16-touch keypad controller,按着这些次序to keep the new battery from discharging:

1. Either plug the sampler into an ac power source, or ensure that it has a fully charged external battery.
2. Make sure the sampler is turned on.
3. Remove the old internal battery.
4. 插入新的内部电池。

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.

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.
