printed circuit boards and cause malfunctioning.
k)
Protect the device from dust and dirt.
l)
Use only new batteries of the size and type indicated
in the technical specifications. Before installing or
replacing the batteries, make sure that the device is
not connected to an external circuit, that the control
knob is set to "OFF", and that the test leads are
disconnected from the terminals.
m)
To avoid electric shock, disconnect the test leads
from the measuring circuits before replacing the
fuse.
To prevent fire, replace a blown fuse only with a fuse
whose rating is F-200mA / 250V.
n)
Do not use the device until the back cover is properly
closed and secured with a screw.
