The HU2700 extends the capabilities of power off testing to troubleshoot low voltage logic circuitry. Its low voltage ranges also make it ideal for testing passive devices such as high value capacitors while still in-circuit. Source voltage, source resistance and test frequency is clearly defined on the front panel overlay. Using a power off test method known as Tracker Signature Analysis, it eliminates the risk of further circuit damage, which often occurs when power is applied.
Modern complex switching power supplies with failsafe protection circuits contain many passive components that are difficult to test in circuit due to parallel solid state devices. The 200mV range of the HU2700 allows resistors, capacitors and industors to be analyzed without turning on the parall
