Time Electronics Model 1024 DC Current Calibrator with Null Measuring Facility Time Electronics 1024 is a readily portable solid state battery-powered calibrator suitable for laboratory, field or industrial use. It incorporates Time Electronics' well-proven circuit techniques. Additionally, the null balance system enables the 1024 to be used for making accurate current measurement. Operation is 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. Applications include calibration and testing of current-sensitive transducers, calibration and linearity tests (on digital and electronic current meters) and semiconductor parameter measurements (such as diode conduction voltages at specified current levels). Simply plugging the 1024 into a mains supply will charge its batteries - a front panel indicator serves as a supply on/off display and monitors the battery supply condition.

Time Electronics Model 1061 Resistance Decade Box Time Electronics 1061 is a low-cost, robust resistance decade box designed to meet requirements for educational and industrial applications. Metal film resistors with a 0.75W power rating are used throughout, conferring the advantages of stability and low temperature coefficient. Six large switches with clear numerical readout enhance ease-of-use. Slim-line design minimises take-up of bench space. 1% accuracy and wide range facilitate production or select-on-test usage. The case provides complete electrostatic screening. Resistance is selected by dialling the required value, using the rotary switches. This enables precise setting with clear unambiguous indication.
