The most important advantage of the on-line style tester is that it can work when the ESP Unit is running. To put it differently, the insulation resistance of the system can be measured without power off and will keep the ESP system running through most common failures. Technical Parameters: The tested system voltage :< 2500VAC Insulation resistance range:0.5Mª+í½2000Mª+ Measures up to 2500VAC Battery powered ú¿12VDC 8 piecesú¬ Accuracy: 2í½1000 Mª+ í+5% Ambient temperature: ú¡25í½+50
