1.0 INTRODUCTION
THE INSPECTOR X-ray source is a complete, single package, portable X-ray device which operates on either AC or from its own self-contained, rechargeable battery pack. The unit incorporates a modular design concept facilitating easy replacement of any of the five functional modules.
The self-contained battery pack feature makes it ideally suited for field use.
THE INSPECTOR is a pulsed X-ray device which produces a pulse of approximately 50 nanoseconds duration, and has a maximum energy of 150 kV. It's major components use solid state circuitry which increases the system's reliability and reduces the power requirements.
Figure 2
2.3 The inverter Module changes the 29-volt battery supply to pulsating AC to drive the high voltage power supply.
The module plugs into the AC/DC Control Module and has a rear connector panel for the AC Cable and Remote Cable. Two fuses are for the protection of the circuits.
2.4 AC/DC Control. This module automatically selects which power supply is to be used. It also supplies the charging current for the battery pack.
The 115 or 230 volt AC power supply is selected by a switch mounted on the circuit card and is accessed through the battery compartment.
Over-voltage protection is provided by two fuses: the GMW1/4 (figure 3) and the 8-amp fuse
(figure 5).

2.0 DESCRIPTION
2.1 This section describes the functional modules and control functions of THE
INSPECTOR X-ray source Model 200.
2.2 The X-ray generator consists of two modules.
The smaller module located at the nose of the unit is a high voltage charging transformer of approximately 9 kV. It is connected to the control circuitry by a printed circuit connector board and to the second module by a high voltage terminal.
The second module (the larger one) is an oil filled high voltage transient generator which develops about 150 kV. The cold cathode X-ray tube is installed inside the unit and is accessible from the front.
Figure 3
2.5 Control circuitry. The control circuitry consists of two printed circuit assemblies which are mounted inside the handle.
They control the power applied to the high voltage transformer via the relay on the AC/DC control board. The vertical board is essentially a programmable counter that counts the number of
X-ray pulses selected, then removes the power to the high voltage transformer.
The delay circuitry, for 15 or 60 second timing, is on the horizontal board, together with the Delay
Start Button and the two indicator lamps.
The Master Power ON/OFF Switch is mounted on the vertical board and is key operated.
2.6.5 Time Delay Start. This push button is located under the handgrip and starts the periods of time delay selected.
2.6.6 Exposure Safety Indicator. This lamp illuminates when either the time delay start button has been activated or when the remote control push button is depressed.
2.6.7 Remote Control Connector. This is a recessed four-pronged connector located on the rear connector panel of the inverter module. This allows operation of the unit from up to 20 feet away by using the control cable.
2.6.8 Power Cord Connector. This is a threepronged recessed connector, located at the rear panel of the inverter module. The Power
Cord is supplied with a USA type molded AC plug, which may be replaced with a suitable connector for different international locations.
An appropriate adapter may also be used.
2.6.9 Fuses. 8 amp ABC 8/15 amp ABC 15
2.7 Power Requirements. THE INSPECTOR Xray Source Model 200 may be operated from either 115 VAC +/- 10% 60 Hz, 230 VAC +/- 10%
50-60hz, or from self-contained rechargeable battery pack. The unit requires approximately
750 watts of power.

3.0 X-RAY TUBE REPLACEMENT
3.1 X-Ray Tube Replacement. The X-ray tube should give long, trouble-free service under normal use. Should replacement become necessary, simply follow these instructions:
A) Unscrew the plastic nose cap on the front of the unit.
B) Carefully grip the outside perimeter of the tube's end cap and pull the tube free from the contact spring fingers. Be careful not to damage the end cap's center; this is a thin, delicate window.
C) CAUTION: Handle tube only by the metal ring. Do not let hands come in contact with glass. (Acid content in body oils may permanently etch the glass, possibly causing decrease of overall life of tube.) If tubes are handled, use rubber or nylon gloves or paper tissue. Tubes may be cleaned with alcohol.
D) Place the tube on a pad of soft material.
E) Clean the nose cap and examine the "O" ring for possible damage. Replace if necessary. Screw the nose cap onto the cavity until the ring makes contact.

4.0 OPERATING INSTRUCTIONS
4.1 IT SHALL BE THE RESPONSIBILITY OF
THE USER TO ASSURE THAT ALL X-RAY
EQUIPMENT BE OPERATED ONLY BY
PERSONS WHO ARE COMPETENT IN ITS
SAFE USE. IT IS IMPORTANT FOR THE
OWNER TO ESTABLISH SAFETY GUIDELINES
AND OPERATIONAL RESTRICTIONS BASED
ON INDIVIDUAL CONDITION AND NEEDS.
4.2 Operating Precautions.
4.2.1 Any individual who could be exposed to radiation from the XR200 should be issued a personal radiation device such as a film badge and/or a pocket dosimeter.
4.2.2 Always stand at a safe distance from the X-ray source. Even though the X-ray beam angle is only 40°, all personnel should remain at least 20 feet behind the X-ray unit while it is pulsing.
4.2.3 Turn the Master Power Key Switch to the OFF position after each exposure.
4.2.4 Review and follow all applicable state and federal regulations.
4.3 Operating Procedures
(CAUTION: Make certain that an X-ray tube is properly installed in the tube chamber.
Failure to have an X-ray tube installed will result in over-voltage which may cause X-ray generator failure.)
4.3.1 DC Mode Procedures
4.3.1.1 Prepare the object to be radiographed and verify that the film is placed in position.
4.3.1.2 Check that the battery pack is installed.
4.3.1.3 Dial the number of pulses required to radiograph the object on the Exposure
Control (see figure 5).
Option A-Remote Hand Switch Operation.
4.3.1.4A Connect the Remote Control
Cable to the four-pin connector on the rear of the panel.
4.3.1.5A Verify the exposure area is clear of all personnel.
4.3.1.6A Turn Master Power Key Switch to the "ON" position and note that the power indicator lamp is illuminated.
4.3.1.7A Depress and hold the hand switch down until the unit has completed the exposure. The exposure lamp will extinguish.
4.3.1.8A Turn the Master Power Key
Switch to the "OFF" position.
Option B-Timer Delay Operation.
(Remote Control Cable removed.)
4.3.1.4B Set the Timer Delay to the required delay time, 15/60 seconds.
4.3.1.5B Verify the exposure area is clear of all personnel.
4.3.1.6B Turn Master Power Key Switch to the "ON" position and note that the power indicator lamp is illuminated.
4.3.1.7B Depress the Start Button and observe that the Exposure Lamp is illuminated. When the exposure is complete, the lamp will extinguish.
4.3.1.8B Turn the Master Power Key
Switch to the "OFF" position.
4.3.2 AC Mode Operations
4.3.2.1 Set the AC Voltage Select Switch, accessible through the battery compartment, to 115 or 230 volts.
4.3.2.2 Connect the power cable to the recessed three-prong plug on the rear of the unit.
NOTE-AC OPERATION CAN BE
ACCOMPLISHED WITH OR WITHOUT THE
BATTERY PACK INSTALLED.
4.3.2.3 The remainder of the AC mode procedures are the same as DC mode procedures.
4.3.3 Duty Cycle Warning. Up to 200 pulses may be used without rest. After every
200 pulses, the operator should allow a rest period of 4 minutes. This a light duty machine. It is not made to pulse continuously.
4.4 Battery Charging. The power source for the
DC mode is a 29-volt, nickel-cadmium battery.
The life of a fully charged battery should be approximately 2000 pulses at 68°F before requiring a recharge. Nickel cadmium batteries of this type, however, do not remain charged during storage.
The battery pack is easily removed from the Xray source by grasping the recessed portion of the cartridge and pulling, while pressing down the molded retaining clip. (see figure 9)
Figure 9
To assure proper performance, the battery should be brought up to a full charge at least once a week. This will require 17 hours for a fully discharged battery.
THE INSPECTOR X-ray Source Model 200 has a built-in charger which operates whenever the AC power cord is plugged in to a service outlet. For safety reasons, the Master Power Key Switch should be kept in the "OFF" position during this process.
For easier battery maintenance and storage, the
Battery Charger/Conditioner Model 2100 is highly recommended.
5.0 MAINTENANCE
5.1 Preventative Maintenance.
The following suggestions will help maintain top performance.
5.1.1 X-Ray Dose Measurement. Check the X-ray dose of each new tube to establish the average dose for that particular tube. The average X-ray dose can be obtained using a dosimeter, such as Victoreen Model 541R
(200 mR or equivalent).
With the dosimeter located 1 foot from the front of the case 9and in line with the center of the CAP TUBE HOUSING), the reading for 30 pulses should be 90 +/-10 mR.
It is desirable to periodically measure the output dose to verify system performance.
CAUTION: Due to the short pulse width,
Geiger Mueller counters cannot detect X-rays emitted from THE INSPECTOR X-ray source
Model 200. We recommend using ionization chambers such as the Victoreen 660 with
660-I probe or Victoreen 541-R pocket dosimeter. Film badges are also sensitive to the INSPECTOR radiation.

6.0 TROUBLE SHOOTING
THE INSPECTOR X-ray Source should never be operated without either an X-ray tube or a shorting strip in the tube cavity. For testing purposes it is preferable to use a shorting strip to prevent unnecessary radiation emission. The shorting strip is a 1/2” wide x 6” long piece of copper connected from tube spring connector to nose cone.
Before testing and repairing the X-ray unit, be sure that a well-charged battery is installed in the unit.
The X-ray unit produces very high voltage (150,000 volts DC). The handle may be safely removed for work on the counter board without exposure to the high voltage. The top case, however, should NOT be removed, except by a qualified technician.
