WARNING!
WARNING!
The devices induce output voltages and currents which conformable to
EN61010-1
are not
dangerous to life. But it is possible that they effect health damages to sensitive persons.
The iseg SHR modules are standalone High Precision HV laboratory SMU – Source Measuring Unit – equipped with the
finest iseg HV generation technology and iCS control system.
The SHR provides up to 4 channels, each with an independent voltage and current control and electronically reversible
polarity. The 6kV channel provides a maximum versatility: with three electronically switchable HV-output modes it can
supply 4mA up to voltages of 2kV, 3mA up to 4kV and 2mA up to 6kV. Alternatively the SHR can be equipped with cost
efficient 2kV/6mA channels.
A high quality 4.3” TFT display shows detailed information and can be controlled by capacitive touch. All comprehensive
features like logging, graphical display and customer specific plugins are also available by the precise jog-wheel and
buttons.
