Wide Range Test Voltage Settings
Features
■
Generate Test Voltages Across a Wide Spectrum
The
can generate test voltages ranging from 250 V
3455
to 5 kV. Settings can be made in steps as fine as 25 V. Very
high insulation resistance measurement up to 5 teraohms is
possible.
Ideal for All Insulation Diagnostic Applications
Functions such as automatic calculation and display of PI
(Polarization Index) and DAR (Dielectric Absorption Ratio),
as well as step voltage test, temperature compensation,
temperature measurement, and leakage current display make
the 3455 suitable for a variety of diagnostic applications.
Data Memory Function
The 3455 provides a manual storage function for 100 data
and a logging function for 10 data (360 times). The date and
time of measurement are also recorded.

Measurement voltage is selectable from 250 V, 500 V, 1.00
kV, 2.50 kV, and 5.00 kV. More finely graded settings are also
possible. When measurement is completed, the unit shows
the insulation resistance value, test voltage (setting and actual
output), leakage current, DAR, PI, and elapsed time.
When measuring insulation resistance, the instrument can be
switched to display leakage current. This is possible before,
during, and after measurement.
