The Sanwa DM1009S is an Analog DC Insulation tester with an accuracy of ±5% of full scale.

The Sanwa DM1009S a DC insulation resistance tester to measure the insulation resistance of electric lines and equipment. The measured voltage is maintained until the low insulation resistance value at the rated current specified in IEC61557-2. This instrument is CAT. III 600V certified.

The DM1009S is equipped with the discharge function to discharge a test circuit once the user is done testing it. The device can measure up to 2000MΩ of insulation resistance when a test voltage of 1000 volts is applied. This instrument can also measure voltages of up to 60V DC and 600V AC with an accuracy of ±5% of full scale.

Includes meter, test leads, carrying case with strap and instruction manual.
