(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.
USB Interface
Easily transfer data to a PC
via the USB interface using
our free PC application
software. The software also
features a convenient report
creation function.

n Primary Measurement Functions
z Insulation resistance measurement
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.
Insulation resistance measurement display
z Leakage current display
When measuring insulation resistance, the instrument can be
switched to display leakage current. This is possible before,
during, and after measurement.

Insulation resistance value
In this type of test, the voltage is gradually raised and the insulation resistance
and leakage current change is measured. Two different step settings are
available: 500 V→ 1 kV → 1.5 kV → 2 kV → 2.5 kV and 1 kV → 2 kV → 3
kV → 4 kV →5 kV. The test time for each step can also be selected.
