Gossen M550R METRISO PRO insulation tester,

Analog insulation, low-resistance and voltage measuring device. Compact and robust, for rough service applications and laboratory use. With the METRISO PRO insulation and low-resistance measuring devices, you can quickly and efficiently test protective measures for electrical systems in accordance with:DIN VDE 0100ÖVE-EN 1 (Austria)NIV / NIN SEV 1000 (Switzerland) and other country-specific regulationsInsulation measurement in accordance with EN 61557-2 / VDE 0413 Part 2 - with test voltages of 50, 100, 250, 500, 1000 VLow-resistance measurement in accordance with EN 61557-4 / VDE 0413 Part 4Voltage measurement up to 1000 V. The insulation measuring devices are suitable for the following tasks:Measuring the insulation resistance of voltage-free devices and systems, up to 1000 V depending on the model.Checking that test objects are voltage-free in networks up to 1 kVChecking the resistance of earthing, protective and equipotential bonding conductorsTesting the conductivity of Floor coverings in relation to electrostatic charges (when using shielded measuring cables) - EN 1081With the so-called 1 mA test in accordance with DIN VDE 0845 / EN 61645, this measuring device can also be used to test the response voltage of overvoltage components (varistors, Zener diodes, etc.) of requirement categories B and C / SPD types 2 and 3) on site and evaluate them according to the manufacturer's data.Discharge of capacitive test objects Capacitive test objects such as cables and windings that can charge up to the test voltage are discharged by the measuring device. The drop in voltage can be observed on the display. Analogue display of measurement and limit values Intelligent filter - measurement-dependent and precise activation when measuring 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 influences Signalling of dangerous contact voltage by LED Signalling of limit value violations by LED External voltage detection in switch position OFF Overvoltage protection protects the instrument if it is accidentally connected to the mains voltage Fuse for all resistance measuring ranges Electronic fuse to protect the low-resistance and resistance measurement RLO and R Device self-test with built-in test resistor 10 M¿ in accordance with EN 50110 / VDE 0105-100 Guard connection to compensate for surface currents Measurements analogue Measuring ranges Riso 10 k ......1 T¿ Riso U = 50, 100, 250, 500 / 1000 V RLO 0.01 ... 10 ¿ U 0 ... 500 / 1000 V Display functions Backlit display, illuminated scale Limit LED Limit (green/red) for: additional acoustic signaling, limit values according to VDE 0100 Riso, RLO LED for dangerous contact voltage (when switched off) LCD symbol for external voltage Battery status display Special functions Discharging capacitive test objects xxxxx Safety shutdown (UBatt < 8 V) xxxxx Equipment Measurement category CAT II 1000V,III 600V Measurement category CAT III 600V, IV 300V Integrated test resistance 10 M¿ DAkkS calibration certificate included, factory calibration certificate. 1 insulation and resistance measuring device 1 factory calibration certificate 1 set of batteries 1 carrying strap 1 crocodile clip 1 cable set KS17-4 1 short operating instructions 1 safety information sheet - Detailed operating instructions can be downloaded from the Internet at www.gossenmetrawatt.com
