The PID insulation tester (TOS7210S) is designed based on the insulation resistance tester (TOS7200) to carry out the evaluation of the PID (Potential Induced Degradation) effect of the PV module precisely and efficiently. Capable of setting within the range of 50 Vdc to 2000 Vdc (resolution 1 V). Ability to switch the applied voltage polarity instantly by the switch on the front panel. The output is floating from the ground potential. Capable of measuring the current value between measurement points. Test leads (TL51-TOS) included.
