Battery Operation
located on the rear of the instrument (see Fig. 16). The 24 V input is protected against reversed polarity of the
battery input source. Protection is also given by a 2 A delayed-action fuse located on the printed-wiring board
of the power supply. This fuse shall be replaced only by a skilled person who is aware of the danger involved.
For replacement, refer to Section 6.1.1. of the Service Manual.
It is recommended that the instrument is not connected to the 24 V battery supply and the mains supply at
the same time.
EARTHING
This instrument has a double-insulated mains transformer; in normal operation this facility obviates the need
for a safety ground.
WARNING
It must be borne in mind that in all measurements the frame ground of the oscilloscope is raised to
the same potential as that of the measuring ground probe connection. Neither the probe's ground
lead nor the frame ground shall be connected to live potentials.
