Note:
Use the instrument under the following environmental conditions if precise source or measurement is your
requirement:
Ambient temperature range: 23±5°C;
Ambient humidity range: 20 to 80% RH(non-condensing)
When using the instrument within a temperature range of 0 to 18°C or 28 to 50°C, add a value based on
the temperature coefficient shown in Chapter 18"Specifications" to the given accuracy rating.
When using the instrument at an ambient humidity of 30% or lower, prevent electrostatic charges from
being produced, by using an antistatic mat or any other alternative means.
Condensation may occur if you relocate the instrument from places with low temperature and humidity to
places with high temperature and humidity, or if the instrument experiences any sudden temperature
change. In that case, leave the instrument under the given ambient temperature for at least one hour to
ensure that the instrument is free from condensation, before using the instrument.
Installing or Replacing the Batteries
Warning
To avoid electrical shock, always remove the source lead cables from the object under test, as well as from the
instrument itself.
Caution
