B.4.1
High precision burden resistor
Gxxx: High Precision Burden Resistor (Option, to be ordered separately)
Low ohmic, 1 W, 0.02% high precision, low thermal drift burden resistor. Uses 4 wire connection to reduce inaccuracy caused by the currents
running to the burden resistor. Using banana input connectors and banana output pins. Directly compatible with GN610, GN611, GN610B and
GN611B acquisition cards.
