Biddle 1818951 Ohmmeter

The Biddle 1818951 Ohmmeter is a resistance-measuring instrument powered by an alkaline cell providing 1 volt and rated for a maximum test current of 100 amps. With the part number 1818951, this device is built to determine the ohmic value of electrical components and circuits by applying a controlled test current and observing the resulting resistance. The 1 V excitation and 100 A maximum establish the device's testing range and current envelope, supporting tasks such as verifying continuity and assessing resistance in cables, resistors, and other low-resistance elements where a precise ohmmeter reading is required. This model focuses on straightforward resistance measurement without the need for external power sources beyond its alkaline cell, making it suitable for on-site or workshop use where quick resistance checks are needed. Common applications include verifying continuity and measuring low-value resistances in cables, windings, and other components within electrical assemblies.
