The HT Instruments Combi519 carries out tests on electric systems in compliance with IEC/EN 61557-1. The COMBI519 features an auto-sequence test function which allows the user to set values for testing parameters with the device indicating compliance or non-compliance with these standards. The device is powered by 6x1.5V alkaline batteries of type AA LR06 supplied with the instrument.

The Combi519 feature these functions:

• AUTO sequence
• Continuity of conductors
• Insulation resistance
• Polarity test
• RCD type AC, A and B general and selective
• Line/fault impedance and prospective short-circuit/fault current
• MCB and fuses
• Phase sequence
• Voltage drop
• Internal memory and connection to PC
