a small amount by applying a fixed resistor across one arm of the bridge. This
shifts the electrical output of the bridge downward to within the operating range
of the meter. A 100 K ohm fixed resistor shifts the bridge output approximately

CAUTION:
1. Where possible, connect the neutral side of the signal (including current shunts) to the input common of the meter. If the input signal is sourced from
an active circuit, connect the lower impedance (usually circuit common) to the input signal common of the meter.
