User's Manual
Warnings
IEC measurement category II includes electrical installations connected to the mains via a
socket on a branch circuit. These devices include most small appliances, test equipment, and
other devices plugged into branch circuit sockets.
Measurement of UT8806E Digital Multimeter
The HI and LO input terminals are connected to the electric mains (up to 300VAC) in these
devices, or to branch circuit socket. However, the HI and LO input terminals of the UT8806E
cannot be connected to the electric mains in permanently installed electrical devices, such as
main breaker panels, sub-panel breakout boxes, or permanently wired motors. These devices
and circuits are susceptible to overvoltage that exceed the protection limits of the UT8806E.
Notes
The voltage above 300VAC can only be measured in circuits that disconnected from the
electric mains. However, transient overvoltage also exist in circuits when disconnected from
the electric mains, and the UT8806E can safely withstand incidental transient overvoltage up
to 2500 Vpk.
Do not use this device to measure circuits where transient overvoltage may exceed this level.
