General Information Introduction 1 Section 1 General Information 1.1 Introduction The Model 07-453 Digital Pulse Counter measures exposure time for a wide variety of x-ray generators. For half-wave x-rays such as dental machines, the instrument is always used in Pulse mode. The instrument will display the number of pulses. For DC or 3-phase x-rays, the 07-453 is always used in Millisec mode. After an exposure, the instrument will indicate the exposure time in milliseconds.
Nuclear Associates 07-453 Operators Manual 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. 1.
Operation General Instructions 2 Section 2 Operation 2.1 General Instructions Switch Settings The front panel selector/toggle switch on the Digital X-Ray Pulse Counter/Timer has three positions: “OFF”, “PULSE” and “MILLISEC”. The switch is OFF when in the center position. OFF All power to the instrument is disconnected in the “OFF” position. Set the switch to “OFF” when not in use, to conserve battery life. The center position is OFF.
Nuclear Associates 07-453 Operators Manual AC Input Connect the two test leads to the two input jacks on the front of the instrument. Since the instrument counts AC pulses, the AC line must be switched by the relay that is in the timer under test. The circuit for AC inputs is completely isolated from the rest of the instrument. No damage to the instrument will occur if the probes are reversed.
