The most convenient way of using the 07-453 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 07-453 at distances of up to 10 feet away from the x-ray.
To use the optional remote sensor, connect the plug at the end of the remote sensor cable in to the jack on left side of the 07-453 case. Point the x-ray head at the target on the Remote Sensor. Stretch the cable out and use as described above.

A jack is available at the left side of the instrument to observe x-ray waveforms. When looking at the Model 07-453 from the left, the connector labeled ‘SCOPE’ the Oscilloscope output. This connector takes a standard 2.5mm mono phone plug.
The Model 07-453 is supplied with one 9 Volt Alkaline battery. Replace the battery when the "Lo Bat" indicator shows in the display. Any standard 9 Volt Alkaline battery can be used in the 07-453. To meet the battery life specification, please use a Duracell MN1604 Battery. This is the familiar “gold top” battery.
The circuitry in the Model 07-453 (above serial number 1001) is completely digital and microprocessor controlled and will not need periodic calibration. As a service Fluke Biomedical will continue to test, verify and issue a calibration certificate for all instruments upon customer request.
There is no warranty on the battery. Fluke Biomedical will replace or repair any Model 07-453 during the first two years after shipment that does not show obvious signs of abuse. Contact the factory as described below.
(in seconds), refer to the Exposure Time Conversion Chart or use the formula Time = pulses / 60 (in countries with 60 Hz power). As shown, the 07-453 would count 6 pulses, and the exposure time would be 6/60 = 0.1 second.

200 milliseconds. It is important to note that the 07-453 will end the count at the end of the x-ray when the intensity drops below about 70% of the peak value. This is done to ensure an accurate count when there is a ”tail” at the end of the x-ray i.e.
