| Description
 The Sanwa DM1009S is a portable, analog insulation resistance meter (also known as a megohmmeter) that can apply a test voltage of up to 1000V DC. It is used to measure the insulation resistance of electric lines and equipment.  | 
| Key Features
 Insulation Resistance Testing: The DM1009S can test insulation resistance with a 1000V DC test voltage, and has a measurement range of up to 2000 MΩ. Voltage Measurement: It also functions as a voltmeter, with ranges for both AC and DC voltage. (AC Voltage: 0–600V AC), (DC Voltage: 0–60V DC). Analog Display: Unlike digital meters, this model features an analog pointer display for clear, easy-to-read measurements. Auto-Discharge Function: The meter automatically discharges any residual voltage in the circuit after a test, enhancing user safety. Overload Protection: It is rated for safety up to CAT III 600V. Measurement Modes: A push switch allows for either one-shot or continuous measurement. Portability: With a compact and lightweight design (approx. 310g without battery), the DM1009S is highly portable. It comes with a carrying case and shoulder strap for convenient transport. Battery Check: The meter includes a built-in function to check the internal battery's condition.  |
