Cable multimeter for measuring symmetrical copper cable systems with signature analysis. The METRAHIT T-COM PLUS cable multimeter is a portable, robust and field-ready measuring device. It is used to carry out measurements to determine sources of errors in cable systems. It measures all cable and system-relevant parameters such as voltage, current, resistance, insulation and loop resistance, capacitance and cable length.A single-wire interruption or contact with an unconnected wire (capacitive asymmetry) can be detected by changing the polarity with the fast logarithmic bar graph display. Insulation resistance measurement (test voltage 10 and 100 V) with simultaneous external voltage detection (at 100 V) and polarity change for diode testingInterference-resistant capacitance measurement and cable length measurementGalvanic signature analysisLine symmetry test by quickly switchingMultifunctional multimeter (V, O, F, Hz, diode test, continuity buzzer, mA, A)RMS measurement TRMS AC and AC+DC for current and voltageLow-pass filter can be switched on 200 Hz / -3 dBDirect current measurement 100 nA ...1 APrecision temperature indicator °C, °F for Pt100 / Pt1000 sensorsDisplay 3¾-digit, 3,100 digits, lighting can be switched on, analogue display: linear or logarithmic for insulation measurementAcoustic signal for: continuity test, dangerous contact voltages, exceeding of overload limitsStorage of min/max values and Auto DATA HoldData memory and internal clock, power supply adapter socketHousing in IP54, dust and splash-proof, rubber protective cover as standardBidirectional infrared interface for data exchange with PCDAkkS calibration certificate included in deliveryManufacturer's guarantee: 3 years for material and manufacturing defects, 1...3 years for calibration (depending on application).
