* X-ray circuit Labeling Diagram *

What is the function of the AC Power Supply?

Provides alternating current at 220-240 volts to the x-ray circuit.

What is the function of the Master Wall Switch?

Connects external power to the x-ray unit.

What is the function of the Fuses?

Break the circuit if a hazard occurs.

What is the function of the Line Voltage Meter?

Measures incoming line voltage to ensure stable 220V.

What is the function of the Line Voltage Compensator?

Adjusts voltage to maintain a consistent input.

What is the function of the Autotransformer?

Makes minor voltage adjustments based on kVp selection.

What is the function of the Major kVp Selector?

Sets kVp in increments of 10.

What is the function of the Minor kVp Selector?

Sets kVp in increments of 1.

What is the function of the Pre-Reading kV Meter?

Displays the kV that will be applied on the secondary side.

What is the function of the Exposure Timer Circuit?

Controls how long the exposure lasts.

What is the function of the Exposure Switch?

Starts the exposure by closing the circuit; dead-man type.

What is the function of the mA Selector?

Regulates filament current to control electron emission.

What is the function of the Focal Spot Selector?

Chooses filament size for small or large focal spot.

What is the function of the Step-Down (Filament) Transformer?

Reduces voltage to 8-12V for the filament.

What is the function of the Step-Up Transformer?

Increases voltage to kilovoltage for x-ray production.

What is the function of the mA Meter?

Measures tube current on the secondary side.

What is the function of the Rectifier Diodes?

Convert AC to DC by allowing current in one direction.

What is the function of the Cathode?

Negative side of the x-ray tube that emits electrons.

What is the function of the Anode?

Positive side of the x-ray tube that receives electrons.

What is the function of the Primary (Low-Voltage) Side?

Contains control panel components except the mA meter.

What is the function of the Secondary (High-Voltage) Side?

Contains rectifiers and the mA meter for DC output.

What is the function of the Filament Circuit?

Controls how many electrons are boiled off for exposure.
