• Excellent repeatability. • Greater accuracy predictable over a wide temperature range. • DC accuracy: 1½%* F.S. • AC accuracy: 2%* F.S. • Resistance accuracy: ± 1½° of arc. Model 270 includes all of the excellent features of the world famous 260, plus a mirrored scale and knife-edge pointer. It offers you dependability, ruggedness, and the higher accuracy necessary for many production and laboratory applications. You get excellent repeatability. The reading you get today will repeat itself when taken under the same conditions at another time. Any change of reading will be in the circuit measured, not in the model 270.
