How To Use A Multimeter To Troubleshoot Your Sensor

use a multimeter to troubleshoot sensorsSo, you’re having problems with the signal from your sensor. Maybe it only works occasionally, maybe there’s too much noise to establish a strong connection, or maybe you just don’t know what is wrong. One easy way to figure out what’s wrong is using a multimeter to test your sensor. Don’t worry, we will walk you through how to use a multimeter to troubleshoot your sensor and get it working properly in no time!

But wait - what is a multimeter and how does it work? Let’s take a quick look. After all, we’ve got a sensor to troubleshoot.

MND Tips & Tricks: Powering The Sensor With The Display Battery

The Modbus Network Display (MND) battery can power a sensorAt the beginning of this year we introduced to you the Tank Cloud MND (short for Modbus Network Display). To review, this display unit connects to a Modbus network to provide local tank level readings. You can program it as a sniffer – displaying readings by “eavesdropping on the conversation” between the slave units and the master – or you can use it as the master and poll the slaves sensors on the Tank Cloud network.

Today we would like to tell you a little more about the MND as a master.

Confused About Relay Lights on your DCR Controller?

DCR-1005 pump controller

If you use the DCR controller, such as the 1003/4 or the 1005/6, you may find yourself looking at blinking lights for relays that aren’t being used. It does NOT mean that something is wrong; it simply means that some default settings need to be changed to deactivate the unused relay.

Keep in mind that the controller is functioning properly, and will continue to do so even if unused relays are not deactivated.

How To Calculate the PSI to LBS Multiplier for an APG Gauge

The PG7 digital pressure gauge lets you use custom multipliers for a psi to lbs conversionOur digital pressure gauges can be set up using the "Custom Units of Measure" function to read in pounds. To do this, you need to figure out the multiplier for converting psi to pounds based on area where the force is applied. The manufacturer of the ram or the hydraulics sometimes provides this. When it doesn't, you'll need to do a few calculations to figure it out.

Open Channel Flow Tutorial Video

Flow volume in open channels is an important measurement for any water management organization, especially in the water and wastewater industry. Furthermore, using an ultrasonic sensor for the measurement is a well established practice - one in which our LPU-2428 excels.

So how does it work? This video tutorial shows how to program the LPU-2428 ultrasonic sensor for open channel flow measurement. Let us know what you think, or if you have any questions.
