Text: Switchcraft Â® StudioPatchÂ® Series DB25 Breakout Cable & Audio Snakes Modular DB25 Breakout Cable Ends Switchcraftâs Modular DB25 Breakout Cable Ends are an easy way to configure your I/O connections without having to replace core cable runs. Make it a habit - discharge all capacitors before testing (even little ones.DB25 breakout board Datasheets Context Search Catalog Datasheet So to answer 'how can the meter be damaged if the capacitor is not discharged', the capacitor itself could be damaged due to high currents, a fuse could be damaged if so equipped, protection diodes could permanently short, reference inductors could be vaporized, and/or other parts of the meter including D2A and A2D converters, even the CPU itself, rendering repair impossible. So in that sense, a polyfuse would not be my first choice for a capacitance testing mode, because it may let in too much current before it warms enough to open. Traditional fuses can be much faster-acting so would be preferred for this role. However heating is slow, and if heated too quickly or too severely (by say, a large capacitor charged to a high voltage) it may never return to a functional status. This is more convenient than a traditional fuse in that it doesn't need replacing and can be reused several times. This 'polyfuse' is designed to 'open' as it gets warm, disallowing further current to flow. Your particular meter apparently uses at least a 600v positive-temperature-coefficient reset-able fuse, likely with other components such as clamping diodes, to reduce the chances of high voltages damaging it while in capacitance mode. And both of these were damaged by connecting charged caps - a diode was welded shorted on the first, and relay contact welded closed on the second. I've heard of at least one other meter which keeps relay contacts closed across the terminals, until the 'test' button is pressed. Some dedicated capacitor testers simply use diodes back-to-back across the terminals for protection, which effectively limit the usable signal to +/-0.6v and anything over this is shorted. Multimeter has overload protection: 600V-PTC. Measuring capacitance is more complicated than other modes because reference components may need to be switched in/out, or the meter may need to sample and electrically 'kick' the capacitor, etc. Usually these are accessible by removing the battery door, or on some models, the outer enclosure. Typically a traditional glass or ceramic fuse will fail, preventing all operation. But violating the limitations of the meter can indeed result in temporary or permanent damage. Most manufacturers are void of operating details. All meters are different, so consult the documentation of yours for any relevant information. Applying large voltages to this can damage components. Calculation from the reference inductor value = capacitance value.īoth of these require small signals and small voltages. Paralelling an inductor, giving it an electronic 'kick', and measuring the oscillating frequency.Injecting a small AC signal into the capacitor and measuring what happens, and/or.

Most multimeters test capacitance in one of two ways: How can you damage DMM if you haven't discharged a capacitor?
