1010 DC Voltage Calibrator

Introduction
1.1
Description
The 1010 is an extremely accurate battery/mains powered voltage calibrator sourcing up to
10 volts in 5 ranges with a resolution up to 0.01µV.
Outstanding accuracy, and stability is achieved by using an LTC advanced subsurface Zener
bipolar reference source; this features a very low drift of 2ppm/°C max TC, coupled with the
use of low temperature coefficient resistors.
Power is provided by a mains/rechargeable battery power unit. A front panel indicator
monitors the battery charge condition.
The circuit design provides automatic standardisation against the internal reference and
allows up to 30mA output current with less than 0.1 ohms output resistance. Short circuit
overload protection is provided; and a normal-off-reverse, (positive-off negative) switch
controls the output signal.
