Description
The Sanwa DM509S is an DC analog insulation tester with a test voltage range of 500 Volts DC.
The Sanwa DM509S is a DC insulation resistance tester to measure electric lines' and equipment's insulation resistance. The DM509S is IEC61010-1 and IEC61010-2-030 CAT. III 600V certified and has an IP20 rating that protects it against dust and other particles.
The insulation resistance function on this device has an accuracy of ±5% of full scale and can measure the insulation resistance of up to 1000MΩ. This instrument is also capable of measuring AC and DC voltages along with a battery check function. The DM509S is equipped with the MΩ (insulation resistance) measuring switch that enables both one-shot or continuous measurement.
Meter includes test leads, carrying case with strap and instruction manual.
