Información
The Datron 1061
1061A and 1071 AUTOCAL
multi-function, microprocessor controlled digital
voltmeters (DVM) are high precision measuring
instruments featuring exceptionally high stability
and systems capability. The basic instrument provides
full DC measurement capability, computation facilities,
self check routines and calibration memory.
The 1061 instrument combines high accuracy with
short measurement time to maximize auability. A 5½
digit display provides a resolution of one microvolt
and an accuracy of 5ppm.
