Page 47: High Voltage Calibration
You must adjust these three potentiometers only when the High Voltage Capacitor Board has been replaced. Contact the Quantel Medical Technical Department to know and check the different voltage values following the different pulses. (1pulse, 2 pulses and 3 pulses).
Page 48 SERVICE MANUAL 7 - ELECTRONIC ADJUSTMENTS Procedure to check the values of the 3 potentiometers : - Connect the voltmeter between the pin 3 and the pin 4. (pin 3 is the power supply and pin 4 is the ground) - Turn On the unit (in service mode).
Page 49: Display Contrast Adjustment
SERVICE MANUAL 7 - ELECTRONIC ADJUSTMENTS By example, we have checked the values on a device, at cold laser and at warm laser. For 1 pulse : - at cold laser, we measured 540 V. - at warm laser, we measured 565 V. To get these values, the P1 potentiometer has been adjusted at nearly 618V.
