Yokogawa 276800 Precision Wheatstone Bridge, 100 „¦ to 110 M„¦

Yokogawa 276800 Precision Wheatstone Bridge, 100 „¦ to 110 M„¦

The Yokogawa 276800 is a Precision Wheatstone Bridge, 100„¦ to 110 M¢„¦ used for the exact determination of resistance in its range, with an accuracy of 0.01 to 0.05%. Since this instrument includes a high-sensitivity transistorized galvanometer and bridge power source, no auxiliary device is required. Product Features: Superior resistor aliment Minimized contact resistance Materials of high insulation resistance and low absorption Guard circuits ensure stable operation even in highly humid atmospheres Housed in metal case to assure operator of excellent shielding Heat-insulated pushbutton keys eliminate operator-to-galvanometer temperature transfer at contact point Measuring Method: Null method (in-line readout). Measuring Arm: 0 to 11, 111¢„¦ adjustable in 0.1¢„¦ steps, (consists of five decades; 1,000¢„¦ x 10 + 100¢„¦ x 10¢„¦ x 10 + 1¢„¦ x 10 + 0.1¢„¦ x 10) Multiplier: x 100m¢„¦, x 1¢„¦, x 10¢„¦, x100¢„¦, x1k¢„¦, x 10k¢„¦, x100k¢„¦, x1M¢„¦, and x10M¢„¦ Accuracy: (at 23‚±2‚°, less then 75%) x 100m¢„¦ range±0.5m¢„¦, x 1¢„¦ range (‚±0.02% of setting +0.5m¢„¦) x 10¢„¦ range, x 100k¢„¦ and 1M¢„¦ ranges±0.02% of setting x100¢„¦ x 1k¢„¦ and x 10k¢„¦ ranges Maximum Allowable Input: 0.2W continuously for ratio arm, 0.2W continuously per element of Measuring arms Insulation Resistance: More then 1000M¢„¦ at 250V DC at ambient Humidity of less then 75% between electric circuit and case Dielectric Strength: 500V AC for one minute between electric circuit and case Galvanometer (Built-In): Max sensitivity approx. 10‚µV/div. (provided with a sensitivity adjuster) Galvanometer Power Source: Single 9V battery (JIS 6F22 or equivalent) Case: Grey metal Case, with plastic feet and carrying handles
