Datron Instruments 1061A Multímetro digital
Fabricante:
Datron Instruments
Modelo: 1061A
Fecha: 1988
Categoría: Los instrumentos de medición
Grupo: Multímetro digital
Descripción: 6½ digit AUTOCAL Multimeter
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.
In the AUTOCAL 1061A, operation of the Input Filter
key extends the display to 6½ digits to provide extra
resolution to 100nV.
