BURNOUT provides the warnsug feature of driving indicator at the end of scale, if the INPUT circuit is OPEN. A burnout resistor is provided which develops a voltage drop between the measuring circuit and amplifier. The polarity of the SIGNAL determines the direction of the servo drive upon an open circuit in the input.

UPSCALE burnout: R value 10 M
Downscale burnout: R value 22 M
