Voltage / current calibrator C.A 1631
5 TECHNICAL CHARACTERISTICS
All of the specifications are guaranteed for one year after calibration, at
temperatures between 18°C and 28°C, with battery power.
The uncertainty is expressed as a percentage of the measurement plus the
possible variation (pts) of the least significant digit.
