4. Produk Lebihview
The VOLTCRAFT R-BOX 02 features multiple banks of switches, allowing for precise adjustment of resistance values. The unit is equipped with 4mm sockets for secure connections.
Rajah 1: Depan view of the VOLTCRAFT R-BOX 02. This image shows the main unit with its array of toggle switches, each labeled with resistance values, and the 4mm input/output terminals at the top. The labels indicate resistance ranges from 1 Ohm to 4M Ohm, with a note about 1% resistors and 0.3 Ohm internal resistance. Instructions at the bottom state "Start with all switches up (OUT) for 0 Ohms. Switch down (IN) to add Resistance value."
Rajah 2: Jarak dekat view of the VOLTCRAFT R-BOX 02. This image provides a clearer look at the individual switches and their corresponding resistance values, as well as the color-coded 4mm banana plug terminals (black, yellow, red) at the top for connecting to external circuits. The text on the device indicates "1% Resistors (0.3W) + 0.3Ω internal" and "1 to 11,111,110 Ω (1Ω step)".
5. Persediaan

6. Operasi
The R-BOX 02 allows you to select a desired resistance value by engaging a combination of switches. Each switch corresponds to a specific resistance value.
6.1 Setting Resistance Values
- Keadaan awal: Ensure all toggle switches are in the "OUT" (upward) position. In this state, the total resistance is 0 Ohms (excluding internal resistance).
- Selecting Values: To add a resistance value, push the corresponding toggle switch to the "IN" (downward) position.
- Calculating Total Resistance: The total resistance presented by the R-BOX 02 is the sum of all resistance values for the switches currently in the "IN" position.
- Example: To achieve a resistance of 123 Ohms, you would push the switches for 100 Ohms, 20 Ohms, and 3 Ohms to the "IN" position.
- Maximum Resistance: The R-BOX 02 can provide resistance values from 1 Ohm up to 11,111,110 Ohms (approximately 11.1 MOhms) in 1 Ohm steps.
6.2 Connection to Circuit
Connect the 4mm banana plugs from the R-BOX 02 to the points in your circuit where you wish to introduce the selected resistance. Always ensure the circuit is de-energized before making or breaking connections.
7. Penyelenggaraan
- Pembersihan: Bersihkan bahagian luar peranti dengan kain lembut dan kering. Jangan gunakan pembersih atau pelarut yang kasar.
- Storan: Store the R-BOX 02 in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
- Pemeriksaan: Periodically check the 4mm sockets and switches for any signs of wear or damage.
8. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Incorrect resistance reading | Switches not fully engaged; incorrect switch combination; faulty connection cables. | Ensure switches are fully "IN" or "OUT". Double-check the sum of selected resistance values. Verify connection cables are not damaged and are securely attached. |
| Tiada perubahan rintangan | Poor connection to the circuit; internal fault. | Check all external connections. If the problem persists, contact customer support. |
| Physical damage to switches or terminals | Improper handling or excessive force. | Discontinue use. Contact customer support for repair options. |
