SOFTWARE

DESCRIPTION

A highly stable and accurate mains or battery powered calibrator suitable for applications requiring a precision

voltage source of low internal resistance. It has ve ranges up to 10V with a resolution up to 0.01μV.
The compact and robust design make it easily portable and well suited to laboratory, eld and industrial use.

A carry case is available to house the instrument for transport or storage.

• Optional carry case

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 500mΩ on the 10V, 1V and 0.1V ranges. The maximum output
current that can be drawn on these ranges is limited to 25mA maintaining specication. The lower ranges have
an output resistance of 1Ω and will supply current up to 30mA.

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

The 1010 can be powered from mains supply or by the internal rechargeable battery pack. When the calibrator

is plugged into the mains supply the internal batteries will automatically start to recharge. If unplugged from the
mains during operation the internal batteries will continue to power the instrument. Full charge allows

40 hours typical use. The battery condition monitored by a meter on the front panel.

Safety Terminals: Fitted as standard and fully compatible with 4mm shrouded plugs, as well as standard

plugs, bare wires, and spade terminals.

APPLICATIONS

The 1010 can be used for calibration, linearity, and gains stability measurements on DC ampliers, digital and
electronic voltmeters, data loggers and chart recorders. It’s high 10ppm per hour stability and very low noise

levels are ideal for these types of applications.
