M201

Precision High Voltage Capacitance Bridge

Precision High Voltage Capacitance Bridge M201 measures the capacitance and dissipation factor (tanδ) with high accuracy

Measuring using M201 requires the use of the external high voltage standard capacitor

Maximum test voltage is limited higest voltage value of standard capacitor
