HID Ballast Testing
HID Ballast Testing2. HID Short-Circuit Lamp CurrentTo assure the Ballast is delivering the proper current under lampstarting conditions, a measurement may be taken by connecting anammeter between the lamp socket center pin and the socket shellwith rated input voltage applied to the Ballast . If available, a socketadapter may be Energize Ballast with proper rated input Measure current with ammeter at A1 and A2 as shown Readings must be within test limits shown on using a clamp-on ammeter for this measurement, becertain the meter is not near the magnetic field of the Ballast orany steel member which might distort the magnetic short-circuit lamp current test results in high, low or noreading, further checks should be made to determine whethercause is attributable to improper supply voltage, shorted or opencapacitor or inoperative Ballast .
