M 3125 EurotestCOMBO appropriate instrum ent installation safety testing and systems. 3125 EurotestCOMBO perform continuity, insulation, RCD, loop, line, voltage, frequency and phase sequence tests required the 61557 standard. Polarity swap: automatic polarity reversal continuity test. Upgradeable: changes occur the regula tions, upgrades can made the firm ware keep the unit date. Insulation range: wide range insulation test voltages from 1000 reading 1000 MQ. Eu rotestCOMBO contains integrated characteristics fuses and RCDs the autom atic evalu ation the line loop impedance results. Testing and systems. TRMS voltage and frequency. Built-in charger rechargeable batteries: unit has built-in charging circuit and comes com plete ith set rechargeable NiMH batteries. Each test has its individual help screen describing how connect the instrum ent into the installation and perform easurem ent. Help screens: instrum ent comes complete with built-in help screens for referencing site. Phase sequence. Built-in fuse tables: this unique feature allows automatic evaluation the line loop impedance results compared the regulations. The red and green LEDs eith side the display provide clear PASS FAIL evaluation test results. KEY FEATURES: LED Pass/Fail indicators: LED indicators for PASS FAIL evaluation test results are placed both sides the LCD. RCD testing (general and selective, type AC, A). Trip Lock function: (RCD) function performs loop impedance test ithout tripping the RCD. RCD auto: automated RCD testing procedure significantly reduces test time.
