Installation / Setup
The setup and installation highlights for the RC-Generator Type SRN BN 4084 include:
1. Mechanical Instrument Zero Point Adjustment: Ensure the instrument’s pointer is on the zero line of the volt scales when the device is off. Adjust by turning the slotted screw in the instrument housing if necessary.
2. Setting and Switching On the Device: The device is preset for 220V. To adjust for 115, 125, or 235V, loosen the screws on the front panel, remove the device from its housing, and bridge the appropriate spring pair on the voltage selector with a fine fuse. Use a 0.3 C DIN 41571 fuse for 220/235V and a 0.6 C DIN 41571 fuse for 115/125V. Reinstall the device, connect to the power supply, and switch on using the toggle switch on the front panel. A glow lamp above the switch indicates the power status.
3. Frequency Setting: The device has one scale for all four frequency ranges (2…20 Hz, 20…200 Hz, 200…2000 Hz, and 2000…20,000 Hz). For frequencies in the higher ranges, multiply the scale value by 10, 100, or 1000 as needed.
4. Output Voltage Setting: Outputs are available through two terminal sockets and a parallel 13-mm coaxial socket. Use 4-mm plugs for terminal sockets and a 13-mm plug (Order No. FS 413/11) for the coaxial socket.
5. Voltage Regulation: In the 30 V/+30 db stage, outputs are connected to the high voltage regulator, and the instrument displays the terminal voltage. The internal resistance varies with the regulator setting, increasing to about 5 kΩ at maximum voltage. A 2-uF capacitor can be switched in to block DC voltage if required.
6. Voltage Divider Stages: In stages from 3 V/+10 db to 0.1 mV/-80 db, a 10-stage 600-Ω voltage divider is used, and the voltmeter measures the open-circuit voltage. This configuration is indicated by green labeling on the front panel.
Operation
The operation and basic usage steps of the RC-Generator Type SRN BN 4084 include:
1. Checking the mechanical instrument’s zero point: Ensure the pointer is at the zero mark on the volt scales when the device is off. Adjust if necessary using the slotted screw in the instrument housing.
2. Setting the mains voltage and turning on the device: The device is factory-set for 220 V. To adjust for 115, 125, or 235 V, loosen the screws on the front panel, remove the device from its housing, and adjust the voltage selector. Use the appropriate fuse for the selected voltage. Reassemble, connect to the mains, and switch on using the toggle switch on the front panel. A glow lamp above the switch indicates the power status.
3. Setting the frequency: The device has four frequency ranges (2…20 Hz, 20…200 Hz, 200…2000 Hz, 2000…20,000 Hz) with a single calibrated scale. Multiply the scale value by 10, 100, or 1000 for the higher ranges. The frequency stability is maintained despite voltage fluctuations or temperature changes.
4. Setting the output voltage: Outputs are available via two terminal sockets and a parallel coaxial socket. The 30 V/+30 db stage connects the outputs to a high-voltage regulator, with the instrument showing the terminal voltage. The internal resistance varies with the regulator setting. A toggle switch can introduce a 2-uF capacitor to block DC voltage from the outputs. For stages from 3 V/+10 db to 0.1 mV/-80 db, a 10-stage 600-ohm divider is used, with the voltmeter measuring the divider’s high voltage.
