16.Refer to Figure 4-2 to connect the C terminals of the Kelvin type sense resistor to the BOP
and connect the DVM to the P (probe) terminals of the sense resistor ((LO terminal of DVM
to common P terminal). Table 4-4 provides recommended sense resistor values for various
BOP current outputs, as well as the formula for calculating expected measured values and
tolerances for any sense resistor other than those recommended. Table 4-2 lists Kepco and
Manufacturer part numbers for those sense resistors recommended.
The sense resistor will be dissipating full rated current of the BOP. If
it is hot to the touch, the sense resistor value, power rating and/or
cooling are incorrect; refer to PAR. 4.4 and Table 4-2.
