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. |
