Datasheet
This datasheet supersedes all previously published material. Specifications that are defined typical
are not guaranteed and are published as general information to the user. The instrument should
have warmed up for at least 20 minutes and the environmental conditions must not exceed the spe-
cified limits of the probe. Note that specifications are subject to change without notice.
