5. As is standard practice for other diodes it is recommended that the Exradin D1H and D1V Diodes be compared regularly to a known calibrated standard under controlled radiation conditions for accurate relative comparison Prior to shipment each diode is verified for radiation performance by comparison to a Standard Imaging Exradin lon Chamber General Operation 1 With nothing connected to the input jack of the electrometer turn the power on and wait at least 15 minutes for warm up 2 Verify the leakage of the electrometer is within the manufacturer s stated acceptable limits 3 Setup the D1H or D1V Diode for measurement in a stand plastic phantom or water phantom When positioning ensure that the active area faces the beam D1H The three vertical lines on the sides of the D12H diode provide references to indicate the center of the active area D1V The laser alignment line around the circumference of the D1V diode indicates the position of the active area NOTE While the D1H and D1V are inherently waterproof without the assistance of sleeves caps or other devices the connector end of the diode should never be submerged in water General Operation Continued av r _ 4 Connect the diode to the electrometer using an extension cable if necessary being certain there is no bias voltage selected on the electrometer 5 Allow the electrometer and diode system at least 10 minutes to stabilize making certai
