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.

Features:

• Test voltage DC500V
• One-shot or continuous measurement push switch
• DCV measurement range (DC60V)
• Auto discharge function
• Inner battery check range
