＊1. In A7-MD-□-D, the insulation resistance and withstand voltage with diode are the values displayed in the "0" position of the dial.
＊2. In A7-MD-□-D, the contact resistance with diode is determined in the positive direction of COM○+, DC6-8V, 0.1A voltage drop method.
35V (MIN.) in the opposite direction.
