• EasyCal 4 Software 10ppm/Year Accuracy The outstanding accuracy and stability of the 9823 is achieved by the use of two carefully selected and aged zeners, averaged to produce a stable master reference. The zeners are selected by computer from a burn-in rig where they are temperature cycled and monitored for 5 months to find the optimum operating current for stability and temperature coefficient. The reference is scaled to the selected output voltage by matched sets of precision hermetically sealed resistors. with tracking and tempera- ture coefficient to better than 0.1 ppm/ºC. Deviation and Offset Digital deviation allows the output to be changed by up to 10% in 1 ppm steps. Errors can then be read off the dis- play directly as a percentage. Offset store enables linear- ity checking of meters with offset zeros without calcula- tions High Voltage Operation Output voltages greater than 40 volts can only be se- lected after pressing a safety interlock key. Once selected there is a programmed 3 second delay, an audible warn- ing bleep and a continuous flashing warning light on the front panel. Front Panel Recalibration Recalibration from the front panel or over the GPIB bus ensures fast, accurate recalibration of the 9823. Calibra- tion can be performed in less than 20 minutes, without the thermal errors created by removing covers. Calibration constants are held in non-volatile memory. A simple ‘cal key’ provides calibration security. Introduction GPIB Interface as Standard The GPIB interface allows the 9823 to be connected to a PC. The simple high level programming language gives full control over the 9823 enabling repetitive cali- bration work to be greatly speeded up. The PC requires an optionally available GPIB interface card. Self-Test and Error Detection The 9823 software constantly monitors the output and displays error messages on detection of a fault or over- load condition. A self-test program can also be run to check that key internal functions are operating correctly and help with fault diagnosis. 1999999 full scale with 4% over-range For accurate calibration of DMM’S the ranges of the 9823 have been designed to match the full scales of most digital multimeters. Six Wave Forms from 15 Hz to 20 kHz The waveforms provided extend the capability of the 9823 to checking ‘RMS’ performance of multimeters, linearity of chart recorders, and amplitude checked on oscilloscopes. EasyCal software - ISO 9000 compatible A suite of programs available from Time Electronics. Automatic calibration using a standard PC and the 9823 is possible and printed certificates to ISO 9000 standard are produced. A wide range of electrical and electronic equipment can be calibrated with full details of each being stored on the PC. Inventory management is also possible so that instruments/equipment can be recalled at predetermined intervals. Calibration job con- trol is also provided.
