High-precision insulation, low-resistance and voltage measuring device. Compact and robust, for rough service applications and laboratory operation. With the METRISO BASE insulation and low-resistance measuring devices, you can quickly and efficiently test protective measures for electrical systems in accordance with: DIN0100 ÖVE-EN 1 (Austria) NIV / NIN SEV 1000 (Switzerland) and other country-specific regulationsInsulation measurement in accordance with EN 61557-2 /0413 Part 2Low-resistance measurement in accordance with EN 61557-4 /0413 Part 4Voltage measurement up to 500 V. The insulation measuring devices are suitable for the following tasks:Measuring the insulation resistance of voltage-free devices and systems up to 500 VChecking the resistance of earthing, protective and equipotential bonding conductorsChecking the test objects for voltage-free statusTesting the conductivity of floor coverings in relation to electrostatic charges (when using shielded measuring cables) - EN 1081. Digital and analogue display, backlitIntelligent filter - measurement-dependent and precise activation during measurement of high-resistance resistors in the case of: - beats, i.e. compensation of 16 2/3 Hz and 50 Hz interference - damping of capacitive influences, e.g. supply lines - suppression of electrical field influencesSignaling of dangerous contact voltageAcoustic signaling when limit values are exceededExternal voltage detection in switch position OFFOvervoltage protection - protects the instrument if it is accidentally connected to mains voltageFuse for all resistance measuring rangesElectronic fuse to protect the low-resistance and resistance measurements RLO and RDevice self-test with built-in test resistor 10 MO in accordance with EN 50110 /0105-100METRISO BASE Article number M550o MeasurementsMeasuring ranges Riso 10 k ... 100 G Riso U = 50, 100, 250, 500 R 10 O... 10 k RLO 0, 01 ... 10 U 0 ... 500Display functionsBacklit displayLimit value LED Limit (green/red) for: acoustic signaling Riso, limit values according to0100 RLO LED for dangerous contact voltage (when switched off) LCD symbol for external voltage Battery status display Special functionsDischarging capacitive test objects Safety shutdown (UBatt < 8 V)EquipmentMeasurement category CAT III 600V, IV 300V Integrated test resistor 10 M DAkkS calibration certificate included. 1 insulation and resistance measuring device 1 DAkkS calibration certificate 1 set of batteries 1 carrying strap 1 crocodile clip 1 cable set KS17-4 1 short operating instructions 1 safety supplement 1 safety information supplement
