H Measurement Channels
Plugs for 8 isolated measurement channels. Connect only original accessories such as
voltage and current sensors (clamps, Flexi Set, shunt resistors, etc.). The plug is secured
by means of a bayonet mechanism.
Note
Inputs that are not in use must be covered with the supplied protective caps
to prevent pollution.
When analyzing transients with 500 kHz transient option or 10 MHz
transient option, the potential to earth/ground is measured.
