Current monitoring resistor
To eliminate output current measurement error caused by
the voltage drops in the leads and connections, connect the
current monitoring resistor (R
M
) between the (–) output
terminal and the load as a four- terminal device. Connect the
current monitoring leads inside the load- lead connections
directly at the monitoring points on the resistor element.
