Acceptance Testing
WARNING: 1. USE EXTREME CARE IN MEASURING HIGH VOLTAGES. ACCIDENTAL CONTACT MAY
CAUSE INJURY OR DEATH.
2. EVEN WITH THE GENERATOR SWITCHED OFF AT THE CONSOLE, (OR THE LOCKOUT
SWITCH INSIDE THE MAIN CABINET LOCKED OUT), MAINS VOLTAGE IS STILL
PRESENT INSIDE THE GENERATOR CABINET. THIS VOLTAGE IS EXTREMELY
DANGEROUS, USE EXTREME CAUTION.
3. THE ELECTROLYTIC CAPACITORS, LOCATED ON THE BASE OF THE HF POWER
SUPPLY, PRESENT A HAZARD FOR A MINIMUM OF 5 MINUTES AFTER THE POWER
HAS BEEN SWITCHED OFF. VERIFY THAT THESE CAPACITORS ARE DISCHARGED
BEFORE SERVICING OR TOUCHING ANY PARTS.
WARNING: THE PROCEDURES IN THIS CHAPTER REQUIRE THE PRODUCTION OF X-RAYS. TAKE
ALL SAFETY PRECAUTIONS TO PROTECT PERSONNEL FROM X-RADIATION.
WARNING: 1. ALWAYS ENSURE THAT THE EQUIPMENT UNDER TEST AND ALL ASSOCIATED TEST
EQUIPMENT IS PROPERLY GROUNDED
2. ENSURE THAT THE HIGH VOLTAGE CABLES ARE INTACT/UNDAMAGED AND
PROPERLY CONNECTED BEFORE ATTEMPTING EXPOSURES
ENSURE THAT THE FOLLOWING ITEMS ARE COMPLETED PRIOR TO PERFORMING THE
ACCEPTANCE TESTING:
•
The generator is interfaced to room equipment noted in the product description.
•
The tube auto calibration has been done as per chapter 2 of this manual.

REQUIRED TEST EQUIPMENT FOR GENERATOR VERIFICATION.

•
KV measuring device such as a dynalyzer (or equivalent). This will be required for verifying kV and mA
calibration during preventative maintenance or if recalibration is necessary, for example after
replacing the generator CPU board or control board 1 in the HF power supply. See note on page 11
regarding use of a Dynalyzer on Indico 100 generators.
•
Storage oscilloscope.
•
mA/mAs meter.
•
Radiation meter 0-1000 mR and 1-15 R/min.
•
Lead diaphragm or equivalent to collimate the beam.
•
General purpose DVM.
•
Strobe or reed tachometer.
•
Current probe 0 to 20 amps AC.
•
