System information
Overrange
Overranges are displayed as long as they exist
and cannot be acknowledged. An overrange
exists if at least one of the four voltage or
current measurement inputs lies outside their
specified measuring range.
If an overrange exists it is shown in the display
with “EEEE“.
The symbols L1, L2, L3 and L4 are used to
indicate at which input the overrange has
occurred. The “V” and “A” symbols indicate
whether the overrange occurred in the current
or in the voltage path.
Important!
Voltages and currents that lie outside
the permissible measuring range can
destroy the device.
