Gossen Metrawatt M542A offre

Caractéristiques

• M542A METRISO G1000A Test Instrument for Insulation, Low-resistance and Voltage Measurements
• Analog display of measured values and limit values
• Intelligent filter - precise and measurement-dependent activation for the measurement of very high resistances- beating, i. e. compensation of 16 2/3Hz and 50Hz interference- attenuation of capacitive influences from power cables, etc.- suppression of electric field influences
• Signalling of dangerous contact voltage by means of LED
• Indication of limit value violations by means of LED
• Overvoltage protection - protects the instrument in the event of inadvertent connection to mains power
• Fuse link for all resistance measuring ranges
• New: Electronic fuse for protection of the low-resistance measurement RLO also protects the fuse link in the low-resistance measuring range in the event of faulty operation
• One measuring point self-test with test resistance of 10 MΩ per EN 50110 / VDE 0105-100
• Guard terminal for compensating surface current
• Good insulation resistance assures safe, efficient, loss-free operation of electrical systems
• Good insulation resistance is the foremost, truly effective fire prevention measure
• Insulation measurement confirms that the respective electrical system is on good operating condition, and is thus important for new systems and handovers – fulfillment of warranted performance
• Insulation measurement is a non-destructive test in accordance with specific stipulations
• VDE 0100, part 600 (IEC 60 364-6), specifies what has to be measured, and where
• In parts 1, 2 and 10, VDE 0413 specifies how measurement must be performed
• Low-resistance measurement (RLO) is also possible per EN 61557-4 (VDE 0413, part 4)
• Convenient compensation of different measurement cable lengths for low-resistance measurements per offset
• The proper functioning can be checked at any time with the built-in 10MΩ test resistance in accordance with VDE 0105-100 (EN 50110-1)
