Service Manual

3128 A14/A15: HV AC 1kHz, Output (Lo)

The instrument is configured to the ac 1100V range with on amplitude of 220V at 1 kHz. The high voltage output is divided and converted to a dc voltage by the OUTPUT PEAK MEASURE circuit to create MUX5. This dc voltage is equal to the positive peaks of the ac amplitude. MUX5 is connected to the SDL line for measurement by the adc circuit on the DAC assembly. The high voltage output is measured for 220V ±12%. A failure indicates the High Voltage Control assembly (A14) is probably at fault.

3129 A14/A15: HV AC 1kHz, Output (Mid)

The instrument is configured to the ac 1100V range with on amplitude of 600V at 1 kHz. The high voltage output is divided and converted to a dc voltage by the OUTPUT PEAK MEASURE circuit to create MUX5. This dc voltage is equal to the positive peaks of the ac amplitude. MUX5 is connected to the SDL line for measurement by the adc circuit on the DAC assembly. The high voltage output is measured for 600V ±12%. A failure indicates the High Voltage Control assembly (A14) is probably at fault.

3130 A14/A15: HV AC 1kHz, Output (Hi)

The instrument is configured to the ac 1100V range with on amplitude of 1100V at 1 kHz. The high voltage output is divided and converted to a dc voltage by the OUTPUT PEAK MEASURE circuit to create MUX5. This dc voltage is equal to the positive peaks of the ac amplitude. MUX5 is connected to the SDL line for measurement by the adc circuit on the DAC assembly. The high voltage output is measured for 1100V ±12%. A failure indicates the High Voltage Control assembly (A14) is probably at fault.

3131 A14/A15: HV AC 100Hz, Output (Lo)

The instrument is configured to the ac 1100V range with on amplitude of 220V at 50 Hz. The high voltage output is divided and converted to a dc voltage by the OUTPUT PEAK MEASURE circuit to create MUX5. This dc voltage is equal to the positive peaks of the ac amplitude. MUX5 is connected to the SDL line for measurement by the adc circuit on the DAC assembly. The high voltage output is measured for 220V ±12%. A failure indicates the High Voltage Control assembly (A14) is probably at fault.

3132 A14/A15: HV AC 100Hz, Output (Mid)

The instrument is configured to the ac 1100V range with on amplitude of 600V at 50 Hz. The high voltage output is divided and converted to a dc voltage by the OUTPUT PEAK MEASURE circuit to create MUX5. This dc voltage is equal to the positive peaks of the ac amplitude. MUX5 is connected to the SDL line for measurement by the adc circuit on the DAC assembly. The high voltage output is measured for 600V ±12%. A failure indicates the High Voltage Control assembly (A14) is probably at fault.

3133 A14/A15: HV AC 100Hz, Output (Hi)

The instrument is configured to the ac 1100V range with on amplitude of 1100V at 50 Hz. The high voltage output is divided and converted to a dc voltage by the OUTPUT PEAK MEASURE circuit to create MUX5. This dc voltage is equal to the positive peaks of the ac amplitude. MUX5 is connected to the SDL line for measurement by the adc circuit on the DAC assembly. The high voltage output is measured for 1100V ±12%.
