Technical Description
General
The 1000 Series calibrators use the latest in reference, resistor and processor
technology designed to minimise cost and size yet maximise performance. The
microprocessor controls and monitors all functions of the calibrator. Calibration
constants are held in a non-volatile memory allowing the calibration to be performed
without removing the covers. There are no internal adjustments required in normal
service.
Warning risk of shock.
The line power cord must be disconnected before removing the
covers of the instrument
The circuitry comprises of five printed circuit boards:
1. Power supply and high current amplifier
2. Main analogue amplifier and feedback board
3. Front Panel Display, resistance range and processor control
4. 10A rectifier PCB
5. Keyboard PCB
