Technical content
The 9814 output is set by transmitting via the IEEE (GPIB) bus a command that represents the output voltage and polarity. For example: the command -9.2142 will set the output to -9.2142 vo lts. The 9814 will automatically select the required range. If required a particular range can be selected by sending R1, R2, R3, R4, R5 or R6 to select the 10mV, 100mV, 1 V, 10V, 100V or 1kV ranges respectively. The required output is then sent as normal. Pre- selecting the range in this way will improve the output setting time under some circumstances. Group Execute Trigger Mode In Group Execute Trigger mode, the required output is stored until receipt of the GET command. 9814 Programmable DC Voltage Calibrator Time Electronics Limited, Botany Industrial Estate, Tonbridge, Kent, TN9 1RH. Telephone: 01732 355993 Fax: 01732 770312 The 9814 is a high performance programmable D.C. Volt age Calibrator. By combining the latest microprocessor and linear circuit technology , exceptional long term stability has been achieved. Computer selection of the basic reference device combined with high performance precision resistors ensure a guaranteed 50 ppm per year stability. Outputs from 0 to 10V may be generated or up to 1.2kV with the optional high voltage board. The high voltage board is fitted internally and gives unit two extra ranges. Construction is based on the standard Euro card frame. Each main section i.e. Microprocessor Control, IEEE interface, D-A Converter, Reference Amplifier etc. are located on a separate pl ug in Euro boards. All boards are easily accessible from the instrument rear. The 9814 may be operated in a manual mode with all controls located on the front panel. * 10mV to 10V D.C. * 100V & 1kV ranges optional * 0.01% accuracy * 30% overrange on all ranges * IEEE/GPIB/HPIB/IEC bus compatible Introduction V5 21/10/03
Type: IEEE 488 (GPIB) Connection: 24 pin connector as pre scribed in the IEEE 488- 1975 standard Addressing: Rear panel switch selects between device no. 0-31 Isolation: All outputs electrically is olated from IEEE bus. (UP to 350V A.C.) Output Connection Front panel output 3 x 4 mm terminals (black, red and green). Rear panel 2 x 4 mm terminals (red and black). Output Polarity True Bipolar output is provided, i.e., the 'Lo' output term inal can remain at earth for all output values and polarities. This eliminates common mode errors or the need to reverse input connections when changing polarity. Overload if the instrument fails to give t he correct output due to internal fault conditions, or output-overloads, the microprocessor resets the output to zero within 10ms and an 'OUTPUT ERROR' message is displayed. Setting Time Less than 1 ms between 0 and full scale. Less than 50ms with range change. Power: 110V/220V/240V AC 50/60 Hz. Power 50 watts. Dimensions: 245 x 437 x 133 mm Weight: 5 kg Optional Extras: 100V/1kV extender board, internally fitted to 9814 extends the output up to 1.2kV in 2 ranges (with a 0.05% accuracy) can be supplied as an optional extra.
