Voltage readings are based on a thermal time constant of 30 minutes with
no more than a 60

internal temperature rise. Internal component heating
is not to exceed 4 W at less than 30 minutes or 2 W at greater than
30 minutes. If the 4 W limit is exceeded in less than 30 minutes, then a
cool-down period of up to 2.5 hours is required for any further probe use.

Voltage ratings are based on a thermal time constant of 30 minutes.

The maximum pulse duration must not exceed 100 ms (see the derating
chart in Figure 1–5 on page 1–13).
