To adjust the shade level on the optrel Crystal 2.0 welding helmet, follow these steps:
1. Make sure the helmet is in the "manual" mode. Use the slide switch on the helmet to select the shade level adjustment mode.
2. In "manual" mode, you can choose between the SL4 - SL8 and SL8 - SL12 shade level range by moving the range switch. Fine adjustments can be made by turning the potentiometer xxxx (grey lettering).
3. If you prefer to use the "automatic" mode, set the rotary xxxx to position "N". In this mode, the shade level (SL4 - SL12) is automatically adjusted to the intensity of the welding arc.
4. If you want to make further adjustments to the shade level in "automatic" mode, you can turn the xxxx to correct the automatically set shade level upwards or downwards by up to two shade levels (green lettering).
Please refer to pages 6-7 of the optrel Crystal 2.0 User Manual for more detailed instructions and illustrations on adjusting the shade level.
