Voltage / current calibrator C.A 1631

5 TECHNICAL CHARACTERISTICS

These characteristics are based on a one-year calibration cycle and are valid for
temperatures between 18 and 28° C, except as otherwi se stated. The uncertainty is
expressed as a percentage of the measurement plus the possible variation (pts) of
the least significant digit.
