• Instruction:
1. Remove the cover of the universal R-box.
2. Solder the resistor and wire as shown below.
To prevent discharge and any accident, make enough space between the resistor
leads and the shield or chassis. For example, make space of about 1 mm from the
leads for maximum 200 V output.
Case 1: installing a series resistor on High, see Figure 3-15 on page 25.
• Connect a wire between Low Force and Low.
• Connect the resistor between High Force and High.
Case 2: installing a parallel resistor between High and Low
• Connect a wire between Low Force and Low.
• Connect a wire between High Force and High.
• Connect the resistor between High Force and Low Force.
Case 3: installing a series resistor on High and a parallel resistor between High and
Low
• Connect a wire between Low Force and Low.
• Connect the parallel resistor between High and Low.
• Connect the series resistor between High Force and High.
Case 4: installing a series resistor on High and a parallel resistor between High
Force and Low Force
• Connect a wire between Low Force and Low.
• Connect the parallel resistor between High Force and Low Force.
• Connect the series resistor between High Force and High.
3. Reattach the cover.
Make enough space between the resistor leads and the cover.
4. Write the resistance value in the label.
5. Affix the label to the top cover.
