1. Overview
The 702902 is a 10:1 passive probe that provides high-voltage measurement when used together
with an isolated input measuring instrument. It can be used over a wide temperature range (–40°C
to +85°C). Except for the tip of the probe, the probe and BNC connector are isolated so that
dangerous voltages are not accidentally exposed. Make sure you also fully understand the correct
use of the measuring instrument when using the probe.
