5. Measurement
5-12
When the time shows SEC (seconds), the weld time is divided into 10-ms blocks
from the start of the weld, and the number in FIRST CYC shows at which block the
measurement begins as shown in the figure below.
For example, when this number is set to 2, the measurement interval is as shown
below.
The blocks from 2 on will be measured.
In the case of DC measurement, when I
