Whether your equipment just finished a measurement earlier this morning or it is fresh out of the box, always assume that there is something wrong with it. Carefully inspect your equipment for any loose wires, worn-down insulation, etc. As they say, it’s better to be safe than sorry.
In the event that you do find something wrong with your equipment, you’ll need to buy a replacement. Whether you need new DC or replacement AC current sensors, or any other type of equipment, make sure you only deal with reputable suppliers like Aim Dynamics. A trusted supplier will have a vast selection of equipment that is sure to suit your needs.
