The 1045 is a high performance combined voltage and current Calibrator with the additional facility for null balance measurement.

The 1045 is comprised of a combination of the Time Electronics 1007 DC Millivolt Potentiometer and Source, and 1021 DC Current Source with null. The voltage and current sections are operated independently.

High reliability and good long term stability is assured by using bandgap zener reference diodes and the use of precision, low temperature coefficient components. The outputs are short circuit proof and protected against overload.

The sensitive electronic null balance meters enable the unit to be used for potentiometric voltage and current measurement in addition to its function as a calibrator. Null zero and sensitivity are adjustable via front panel controls. Maximum sensitivity is 1µV for voltage measurement and 1µA for current measurement.

This portable current and voltage calibrator is one of the well-proven Time Electronics portable testing equipment line. It gives the user accuracy and reliability as a calibrator and potentiometer, with null balance measurement capabilities.
