Three Steps to Determine If Your 4 Channel Data Logger Needs Repairs

Is your data logging system recording incorrect readings, but you’re unsure of the leading cause? Are you wondering if your 4 channel data logger may need repairs? If so, then you’ve come to the right article! We’ll be discussing some simple steps that you can perform to help determine if your data logger has either a hardware or a software measurement problem and whether you need to return your data logger for repairs.

 

We’re fully aware of the frustrations you get if you send your data logger in for repairs. To avoid costly repairs and other inconveniences, we’re hoping that this article will be of tremendous help in giving you some useful insights on what you can do once your 4 channel data logger encounters problems.

 

Step 1: Check the Power

 

If your data logger isn’t receiving enough power, it’s highly unlikely that any other device in your data acquisitions system will work properly. Issues with charge regulators and the battery itself account for most data acquisition system failures. So, make sure you check your power if you’re getting enough juice or if it’s not producing sufficient amounts to achieve accurate readings. If the case is the latter, then you need to get it fixed right away. For a complete step on how you can check your power, visit our website now.

 

Step 2: Check the Analog Ground

 

The next step is to rule out a problem using the analog ground channels. Most channel data loggers have two types of ground channels: analog ground and power ground. The former has a smaller yet higher-resistance trace that reduces noise on the sensor voltage readings. Both the power and analog ground channels are electrically connected. However, a power surge can potentially break the analog ground trace. This break would force the sensor signals to travel to the ground via diodes in the wiring panel, which can cause incorrect readings. If this is the case, try to fix it. Again, refer to our separate guide on how you can do this.

 

 

Simplify the System

 

Finally, sometimes sensors that require a power supply of more than five volts pull the data logger out of a more typical range. The best way to prevent this possibility is to simplify your data acquisition system by discovering all the powered sensors.
