Description:

The 1010 is a solid state battery powered instrument suitable for applications requiring a precision voltage source of low internal resistance. It has five ranges up to 10V with a resolution up to 0.01uV. Its small size, robust construction and independence of mains power make it easily portable and convenient for laboratory, field and industrial use.

Voltage outputs are set by selecting the range switch and dialling up the desired value on the thumbwheel switch. Output polarity may be selected using the normal/off/reverse switch.

The calibrator’s output resistance is typically 500mOhms on the 10V, 1V and 0.1V ranges. The maximum output current that can be drawn on these ranges is limited to 25mA maintaining specification. The lower ranges have an output resistance of 1 ohm and will supply current up to 30mA.

Operation is from battery or mains. When the calibrator is plugged into the mains supply, the internal batteries are automatically recharged. The internal batteries will operate the calibrator when unplugged from the mains. Battery condition can be monitored by the meter on the front panel.

A precision zener diode is used as a reference source that provides an input to a F.E.T. chopper amplifier system operating in a feedback stabilised mode. The gain value is determined by a set of precision metal film resistors, selected by the 5-decade thumbwheel switch on the front panel. The output voltage is variable from 0.01uV to 9.9999V in 5 ranges.

For complete reliability, the calibrator range switch employs two contacts in parallel for each position in case one contact fails, ensuring the calibrator will still function correctly.

Applications include calibration, linearity, and gains stability measurements on DC amplifiers, digital and electronic voltmeters, data loggers and chart recorders. It’s high 10ppm per hour stability and very low noise levels are ideal for this type of application.
