STATISTICS BATCH SIZE

channel can also be programmed with a batch size of 0.
When the batch size is 0, the channel enters a “running statistics” mode. The EPM2000 constantly
tracks the minimum and maximum pulse energy read by that channel. Toggle between displaying the
current maximum and current minimum values by pressing
or . Press to clear the two

channel can be set independently.
Set the Trigger Holdoff by pressing
