Yokogawa 275597 Precision Wheatstone Bridge, 1 „¦ to 10 M„¦

Yokogawa 275597 Precision Wheatstone Bridge, 1 „¦ to 10 M„¦

The Yokogawa 275597 Precision Wheatstone Bridge, 1„¦ to 10 M¢„¦ measures resistances by operation of dials and switches; its batteries and a galvanometer are self-contained. The front control panel is provided with power and galvanometer circuit selectors, one ratio arm, and four measuring dials. Model 2755 is also equipped with a Murray and Varley Loop Tester for convenient location of line faults such as shorts and grounds in power, telephone, telegraph, and signal cables.  Product Features: No auxiliary attachment required Galvanometer with built-in protection circuit Compact, lightweight (2 kg) Built-in Murray and Varley loop tester Measuring Range: 1.000¢„¦ to 10.00M¢„¦ Measuring Arm: x 1m¢„¦, x 10¢„¦ + 10¢„¦ x 10 + 100¢„¦ x 10 + 1000¢„¦ x10 (min. one step: 1¢„¦) Ratio Arms: x 0.001 x 0.01, x 0.01, x 0.1, x 1, x 10, 100, x 1000 (M10, M100, M1000 Murray and Varley loop testing) Accuracy: Range,±0.1% of reading on 100¢„¦ to 100k¢„¦ Range,±0.3% of reading on 10¢„¦ to 1M¢„¦ Range,±0.6% of reading on 1¢„¦ to 10M¢„¦ Range Temperature Coefficient of Resistance Elements:±0.5 x 10-5 /‚°C at ambient temperature of 5 to 35‚°C (41 to 95‚°F),±2 x 10-5 /‚°C at ambient temperature of 20 to 35‚°C (68 to 95‚°F) Galvanometer (Built-In): Sensitivity 0.9 Ž¼A/div, Internal Resistance - Approx. 150¢„¦, External Critical Damping resistance - Approx. 800¢„¦, Period - within 1.5 Seconds Galvanometer Power Source: Three 1.5V batteries (built-in) Operating Temperature Range: 5 to 35‚°C (41 to 95‚°F) Humidity Range: 85% Max., Relative Humidity Outer Case: ABS Resin
