Page 9: Vi.measuring Principle
VI.Measuring Principle Insulation resistance measurement uses a voltage generator to generate a voltage, V, applied across the resistor, measuring the current I flowing across the resistor, and calculating the ground resistance value R according to the formula R=V/I. VII.Operation Method 1．Power On/Off Press the POWER button to turn the switch on and off. -

Page 12: 6．Guard Use Of Protective Wires
6．GUARD Use of Protective Wires When the insulation resistance of the cable is measured, the leakage current of the covered surface passes through the interior of the insulator and the current converges, resulting in an error in the insulation resistance value. In order to avoid this phenomenon, as shown in the figure below, use the protection wire (any conductive bare wire) to flow the leakage current through the part. - Page 13 short-term insulation resistance ratio DAR is called the absorption ratio (see the following formula for the specific test time), but for large-capacity long-term absorption process, such transformers, generators, cables, capacitors other electrical equipment, sometimes the absorption ratio (DAR) is not enough to reflect the whole process of absorption, and the insulation resistance ratio can be used for a longer time, that is, the ratio between the insulation resistance (R10min) at 10 minutes and the insulation resistance (R1min)
