Gossen Metrawatt M550S Metriso Xtra Test Instrument for Insulation

Gossen Metrawatt, M550S, Metriso Xtra Test Instrument for Insulation, Low-resistance and Voltage Measurements, with Memory

M550S Includes Only:

• 1 Insulation and resistance measuring instrument
• 1 DAkkS calibration certificate
• 1 Set of Batteries
• 1 Carrying strap
• 1 Alligator clip
• 1 Cable set KS17-4
• 1 USB cable
• 1 Condensed operating instructions
• 1 Supplement Safety Information

Features:

• Test voltages in fixed increments, variable, or as a ramp 50, 100, 250, 500, 1000 V
• Polarization index and absorption ratio
• Intelligent filter - precise and measurement-dependent activation for the measurement of very high resistances - beating, i. e. compensation of 16-2/3 Hz and 50 Hz interference - attenuation of capacitive influences from power cables, etc. - suppression of electric field influences
• Signaling of dangerous contact voltage
• Acoustic signaling when the limit value is exceeded
• Detection of interference voltage in switch position OFF
• Overvoltage protection - protects the instrument in the event of inadvertent connection to mains power
• Fuse link for all resistance measuring ranges
• 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
• Backlit dot matrix display for measured and limited values
• Timer function 1 s - 100 Min
• Guard terminal for compensating surface current

Applications:

• Measurement of insulation resistance at voltage-free devices and systems, up to 1000 V
• Testing of the resistance of earthing conductors, protective conductors, and equipotential bonding
• Checking of test objects for the absence of voltage
• Testing of electrostatic discharge capacity at floor coverings (using shielded measurement cables) - EN 1081
• With the so-called 1 mA test per DIN VDE 0845/EN 61645, the instrument also allows to perform of on-site tests of the response voltage of overvoltage components (varistors, Zener diodes, etc.) of requirement categories B and C / SPD Type 2 and 3) and to evaluate the test results in accordance with manufacturer‘s Data.

Compact and rugged - for service calls under harsh conditions and laboratory use.
