Metravi DIT-950 and DIT-951 High Precision IR Testers are intelligent measurement instruments that are used for rapid measurements on insulation resistance properties of electronic parts and components, dielectric materials, equipments, cables, etc.

Approved by BIS. Large LCD and user friendly menu provide you easier operation. This instrument is especially designed for capacitor insulation resistance test and can achieve rapid measurements through following methods:

1. Selectable internal input impedance: If the current is greater than 10nA, only 10kΩ input impedance can be used; if the current is below 10nA, you can choose 10kΩ or 1MΩ impedance to test.
2. With the built-in dual voltage output, it can charge large capacitors. By dual voltage output, it is able to output a pre-charge voltage up to 500V, 200mA. In voltage follow mode, pre-charge voltage follow with the test voltage output and can be finely adjusted. Above features ensure the perfect charge of capacitive materials.
3. DT-951 can output a voltage of 1000V, 100mA to fully charge the capacitive material. In addition, user can program the sequence measurement steps (up to 18 steps) on. For instance, charge, wait, test, and discharge steps can be programmed. Each step can last up to 100s. The instruments have a unique contact detection function.
4. For capacitive material such as capacitors and cables, contact detection function can detect the contact of components under test. Moreover, this detection function will not increase any test time. They are equipped with interfaces of RS232, USB DEVICE, SCANNING and Handler. Handler interface provide convenience for automatic test system; SCANNING interface is useful for mass measurement of components. User can use a scanner to speed measurement of components.
