Cable Multimeter for Measurements in Symmetrical Copper Cable Networks – with Signature Analysis
The METRAHIT T-COM PLUS cable multimeter is a rugged portable measuring instrument for use in the field.
It performs measurements for pinpointing errors in cable networks. It measures all cable and system related parameters such as voltage, current, resistance, insulation and loop resistance, capacitance and cable length.
Interruption of a single core, or contact with an open-circuit core (capacitive asymmetry), is detected by means of polarity reversal and is indicated at the high-speed logarithmic bar graph display.
- Insulation resistance measurement (test voltage: 10 and 100 V) with simultaneous detection of interference voltage and polarity reversal for diode testing
- Interference-immune capacitance measurement and cable length measurement
- Galvanic signature analysis
- Cable symmetry testing by means of rapid changeover switching
- Multifunctional multimeter (V, Ω, F, Hz, diode testing, acoustic continuity, mA, A)
- TRMS measurement, TRMS AC and AC+DC for current and voltage
- Low-pass filter can be activated (200 Hz / -3 dB)
