Overview
The HDRT-310 is an automatic hand-held battery operated transformer ohmmeter, allows the user to operate the test set while holding it in one hand. It offers 3 test channel up to 10A with a range from 500µΩ to 50kΩ. It effectively eliminates the user from having to kneel or bend down to operate the instrument and speeds up testing time, with a weight only 1.6kg
