Check zero position of the UV - meter
Before the illumination check the zero position of the UV
–
meter has to be checked. For this purpose

is on switch the lamp off and switch the UV
–
meter off and on again.
Read the display value and document it in the protocol. Compare the value with the setpoint (0,0 ±
0,1 mW/cm²). If the value is outside of this range it is not allowed to perform a treatment with the
device. Please contact your distributor.
