    1. Introduction , Application and Features: Power Clamp meter is a Portable Digital multi functional measuring instrument designed for Measuring selected power network p a r a m e t e r s , AC/DC V oltage, AC/DC current, Resistance, Co n t in u i t y , Diode and Freque n c y Apart From basic quantities meter enables the measurement of additional quantities calculated from values of voltage and current.
  • Page 6 T ake into account that unexpected voltages can occur on devic e under test (e.g.defective instrument).For example, capacitors may be charged to a dangerously high voltage. V erify that the test leads are in good condition, e.g.no crac ked insulation, no open circuits in the leads or connectors. This clamp meter must not be used for measurements on circuit s with corona discharge (high voltage).
