PC-Gentec- EO User’s Manual Revision 5.0 22
Caution! If you select a high value trigger level, the PC-Gentec-EO may not be able to detect all the
values of widely varying energy levels in auto range mode. The auto range function uses the energy
level of the last pulse to set the scale level. Therefore, it will not detect the next pulses if they are lower
than the trigger level. As a result, the auto range may become caught on a high scale value. To avoid
this problem, select a lower value for the trigger level, change the scale manually, or reset the auto range
mode by reselecting auto in the Range menu (section4.3.2).
Erratic triggering?
In electrically noisy environments, it is possible that the PC-Gentec-EO will inadvertently trigger
on the noise. If this is the case, increase the trigger level to 3% or higher if necessary.
It is always good practice to reduce electrical noise generation or shield the detector and
monitor when measuring very low pulse energies.
You can also set the device to be triggered externally. Just click the External Trigger check box (not
available on the Integra).
