We design these as per ISI standards to test electronic components such as paper Capacitors, Plastic Capacitors, Ceramic Capacitors, Insulators, Semi Conductors, Switches, Connectors, Transformers and Motors. These testers are equipped with the facility for checking insulation resistance in the range of 1 megohm to 10 million megaohm after one minute of charging. These permit measurements of intrinsic value of insulation resistance if required, even with capacitive loads. Moeover to make is suitable for rapid and safe testing of components in a factory, these are given with separate push button controls and visual indicators for "Charge", and "Discharge" function. We have limited the maximum output current to safe value for eliminating the risk of serious shock to operators. These are available in five models as per specifications ideal for the clients. The salient features are as per the following: • Push Button Controls for rapid testing. • Tests as per I. S. I. recommendations. • Wide measurements range • Fully protected against all overload and short circuits. • Completely solid state circuitry, hence drift free operation. • Guard Terminal provided. • Suitable for testing 'EARTHED' Samples. • Suitable for testing insulation liquids (Resistivity Measurements) with oil cell as per IS : 335
