Voltage drop caused by the R-box must be subtracted from the measurement result as
following.
Vdut = Vout

Imeas
where, Vdut: Voltage after correction, Vout: Source output voltage, Rs: Resistance of the
series resistor, and Imeas: Measurement current
To Use Universal R-Box
To install your desired resistor, see the following simple instruction.
•tRequired parts:
wire, adequate rating, length, and quantity
your desired resistor, adequate rating
hexlobe (torx type) screwdriver T-10
label, for noting resistance value
• 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, 6 mm for 3000 V, and 32 mm for 10 kV.
Case 1: N1262A-020/021, see Figure 5-1 .
• Connect a wire between a terminal and the center conductor of its near
connector.
• Connect a wire between the other terminal and the center conductor of the other
connector.
• Connect the resistor between the terminals.
