The most convenient way of using the Digital X-Ray Pulse Counter/Timer is to place it directly under the
x-ray head. Step back, take the exposure and then read the exposure time in pulses or milliseconds. An
optional remote sensor is also available to allow use of the instrument at distances of up to 12 ft away
from the x-ray.
