They provide • Measurement of cell voltages, for example in on- an expanded measuring range, greater accuracy and board batteries and emergency power supplies easier reading. As universal measuring and test • Contact resistance testing at welding seams instruments, they acquire and record values to an integrated memory module including resistance in the DKD Calibration Certificate milliohm and micro-ohm ranges, as well as “normal The DranTech PMIT is furnished with an multimeter resistance values” in the ohm to mega- internationally accepted DKD calibration certificate ohm ranges by feeding a measuring current to the (recognized by EA and ILAC). After the specified resistor, conductor or device under test DUT. The calibration interval has elapsed (recommended respective measuring current is determined by the interval: 1 to 3 years), the PMIT can be inexpensively rotary selector switch setting and lies within a range of recalibrated by any calibration laboratory. 1 to 0.02 A in the milliohm ranges. The instrument also measures and records insulation resistance with Scope of Delivery test voltage selectable in steps, for example in order • PMIT Multifunction Meter with protective to test resistance in on-board electrical systems for rubber holster aircraft, ocean vessels, etc., and for testing • Rechargeable NiMH batteries + Charger overvoltage arresters and much more. • DranWin 10 Software • CD with operating instructions, Easy Operation Operation is very easy. Simply connect the low- • DKD calibration certificate resistance device under test to the instrument with the • HC30 Hardcase for Meter & Accessories included measurement cables, Kelvin clips or 4-wire probes (KC27), and select the proper measuring Optional: Kelvin Clips KC4 + KC27 range.
