When measuring energy with a thermal head there are two parameters that can be adjusted: the energy scale and the trigger threshold.\u00a0 Although it might seem complicated at first, choosing the right energy scale and threshold can be accomplished by following these simple guidelines.<\/p>\n

<\/p>\n

First, we must choose the energy scale.\u00a0 This is easy.\u00a0 Choose the lowest scale that is still higher than your laser energy.<\/p>\n

Now we need to set the threshold.\u00a0 A high threshold is important, so noise or vibration doesn\u2019t trigger an energy event.\u00a0 On the other hand, if the trigger threshold is too high, we might cause the meter to reject actual pulses as noise or degrade the accuracy of the measurement.\u00a0 For this reason, we suggest the following guidelines:<\/p>\n
