Application Measurement
Introduction
This chapter provides actual measurement examples and note on measuring insulation
resistance of capacitors.
Warning
The measurement system using the 4349B and the external voltage source
may output dangerous voltage. To prevent an electrical shock, observe the
following safety precautions.
Agilent Technologies recommends you to attach the safety interlock
function to the measurement system so that the operators can not touch
the parts where dangerous voltage may appear. If not possible, warn the
operators and the workers around the measurement system not to touch
the parts.
Use the parts with the safety function to prevent an electrical shock
caused by the insulation breakdown, even if dangerous voltage does not
appear on the parts directly.
Turn OFF the output of the external voltage source and discharge
the remanent charge of the DUT thoroughly, before touching the
measurement system or the DUT where the dangerous voltage may
appear.
Use the power cord shipped with the 4349B and provide an
uninterruptible safety earth ground to the instrument.
Do not apply a dc voltage exceeding
terminals.
Agilent Technologies warrants the 4349B and its accessaries provided by
Agilent Technologies. Agilent Technologies does not warrant any accidents
caused by trouble in an external voltage source or the measurement
system.
Caution
Do not apply a dc voltage exceeding
terminals, or the 4349B's input circuits will be destroyed. Connect a current
limitting resistor to avoid the over current when a shorted device is connected.
