Megger DET4TCR2 电气检测
Megger DET4TCR2 Earth & Ground Resistance Tester 20000Ω CAT IV 100 V
Megger
DET4TCR/2 4 Pole Earth Tester 4 pole earth tester with rechargeable batteries for measuring soil resistivity and resistance of earth rods and associated installations.,An ICLAMP selective clamp is available separately, and when used with the DET4TCR/2 allows the testing of an earth rod without the need for disconnection from the system.,A VCLAMP is also available separately, which when used in conjunction with ICLAMP allows stakeless measurements to be made in situations where driving auxiliary stakes is not practical. Resistance range 0.01 to 20k ohms auto rangingChoice of 2, 3 or 4 terminal measurementsSimple one button operationSuperior noise rejection to 40V pk-pkMeasures earth voltage 0 – 100VAutomatic P spike and C spike checkClamp input for no-disconnect testing (required ICLAMP)Clamp inputs for stakeless testing (required ICLAMP and VCLAMP)Earth current range (requires ICLAMP) Resistance range 0.01 to 20kΩ Accuracy 2% ± 3 digits Ingress protection IP54 Output ±25V or ±50V Test frequency Hz 94.105.111 Earth current range with ICLAMP 0.5mA to 19.9A Display LCD with back light Operating temp. -15 → +55 °C Standards EN61010-1 CAT IV 100V Supplied with 4 earth test stakes, 4 connection leads, 8 x AA NiMH rechargeable batteries, hard carry case, mains charger, quick start guides, user guide on CD Earth Testing ; Absolute Maximum Resistance Measurement 20000Ω; Best Accuracy ±2% + 3 Digits; Display Type LCD; Safety Category CAT IV 100 V; Battery Life 3 h; Battery Type AA; Power Source Battery; Dimensions 203 x 78 x 148mm; Weight 1kg; Height 148mm; Includes Calibration Certificate, Case, Spike, Test Lead; Length 203mm; Maximum Operating Temperature +55°C; Measurement Type Soil Resistance, 4 Terminal Earth Resistance; Width 78mm; Minimum Operating Temperature -15°C; Model Number p DET4TCR2;
