3. Operation Instruction
(1) Laser Tube connection: (Referring to Power supply and laser device's connection diagram)High voltage terminal(HV+) of HY-DY20 power supply should be connected to the positive pole of CO2 laser device. Current circuit of the power supply shall be connected to negative pole (laser output terminal) of laser device, through an ampere meter or directly.
(2) Connection of control signal: The control signal shall be reliably connected to control terminal of the power supply HY-DY20, after connecting the DAC output signal and TTL signal of external computer with the power supply, the laser device shall work as expected. If the laser lamp can not work properly, should check the control signal is correct or not (include check the voltage specification and logic), if use PWM control as power control,make sure f≥20KHz,Amplitude(peak value)≤5V, check and make sure protection switch WP connection is correct at same time.
(3) Voltage of power input: HY-DY20 's power input of the power supply shall be 220VAC/50Hz. If 110VAC is needed, please specify when placing order.
(4) Others: A group of protection switches are also reserved for detection of water switch, fan switch, open-enclosure protection and so on.

4. Caution:
(1) Water cooling system should be working properly when switching on laser device.
(2) Circuit of high voltage output should not be open! (High voltage output terminals (positive and negative poles) shall be properly connected to positive and negative poles of laser device, respectively).
(3) Attentions should be given to avoid any electric shock after the power supply being switched off (The Insulation safety requirements should be 50KV between the terminal of output and "G").
(4) Well-grounded three-pole receptacle should be used to supply power to HY-HVCO2/1.6 power supply. The enclosure should be well grounded to avoid electric shock.

Miracle cream!
This cream is unbelievable. goes in instantly, makes hands soft after one application and creates a barrier to protect your hands against cold and water. I live in VT and have tried numerous "extreme" hand creams that are heavy and greasy and useless~ this one is the best. I also like that it is fragrance-free except for that mild "Avene" spring water smell. I have two tubes, one for my night table and one next to the kitchen sink. I am 47 and have tried numerous face and body products`` you could say I used to be a "junkie" :) but I always come back to Avene. I have extremely sensitive skin and Avene products are a life saver.

My 75 year old hands appear softer and younger!
Avene Cicalfate Restorative Hand cream leaves my hands feeling very soft! A little goes a long way, I have had mine for a year. Soon I will be purchasing another tube. Yes, it is a little pricey for a hand cream, but does the job better then any other product I have used on my hands. Highly recommend this hand cream if you have dry, sensitive skin. It also has no added fragrance which I really appreciate!

Excellent product at a very good price. I will buy it again.
This is an excellent product at a fair price. The cream creates a barrier that protects the skin, while mosturizes it. leaves hands very soft, and it doesn't feel greasy. I know that this is a favorite brand (Avene) in France, and Amazon offers it at a very good price. I will buy it again, from Amazon. I bought it this year in Paris, and it was more expensive there.

Drying formula and smell bad
Smell so bad and made my hands dry instead of moisturizing. The formula is watery. Maybe it’s fake or expired I am not sure.
