The 1024 is a solid state battery powered, portable test instrument ideal for laboratory, field, or industrial use. It incorporates many of the well-proven circuit techniques of the Time Electronics Type 1010 DC Voltage Calibrator.

The null balance system enables the 1024 to be used for making accurate current measurement in addition to its basic function as a calibrator. Operation is performed by backing the current source output against the current to be measured, with the difference being displayed on a sensitive centre zone null meter. At the null point, there is no voltage drop across the 1024.

The 1024 employs a precision aged reference diode as a basic reference source. Excellent zero stability is ensured by the use of a high performance FET chopper amplifier system.

Precision metal film resistors with temperature co-efficients of less than 10 ppm per ºC are used to maintain the accuracy and stability of the initial calibration.

Applications include calibration and testing of current sensitive transducers; calibration and linearity tests on digital and electronic current meters; and semiconductor parameter measurements e.g. diode conduction voltages at specified current levels.

This precision DC current calibrator is one of the Time Electronics portable testing equipment line, with multiple capabilities it delivers accuracy and reliability in one instrument.
