Also, you should run at least three trials and average UVA or UVB intensity.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 8pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">A few things to note: Your sunscreen should never be placed on the sensor. If you apply sunscreen to the plastic, the sunscreen side <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 8pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> should be facing out.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 8pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">A note about using UVA or UVB sensors. Stop data after 20 seconds. Use statitstcs function to determine the mean UVB or UVA intensity.

Clamp UVA probe to the ring stand and point it toward the sun <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 8pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 3.

Hold sunglasses directly over probe and take reading. Record reading and repeat 2 more times. Find average. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 8pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> 8.
