GMC-Instruments 高美测仪 M550P 兆欧表

"The METRISO TECH insulation and resistance measuring instrument allows for quick and effective testing of protective measures in accordance with: DIN VDE 0100, Ã-VE-EN 1 (Austria), SEV 1000 (Switzerland) and regulations specific to other countries as well.Insulation measurement per EN 61557-2 \/ VDE 0413 part 2. Low-resistance measurement per EN 61557-4 \/ VDE 0413 part 4. Voltage testing and measurement up to 1000 V. Intelligent filter: precise and measurement-dependent activation for the measurement of very high resistances. Digital and analog display, backlit. Indication of dangerous contact voltage LED. Acoustic signalling when 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 the protection of low resistance and resistance measurement Rlo and R. Compact and rugged for service calls under harsh conditions.
