About This Product
In college and technical laboratories the unit acts as the known resistance when balancing a Wheatstone bridge, and it is also used to check ohmmeters and digital multimeters against a fixed value. For Electrical And Electronics measurement work, a low test current is used because self-heating can shift the resistance.
Frequently Asked Questions
Q1. Why should a low measurement current be used?
Current causes self-heating, which can change the resistance and reduce measurement reliability. Stay within the documented current and power limits.
Q2. Can it be connected directly to mains electricity?
No. The unit is meant for controlled measurement circuits only.
