When pushbutton
'L
is selected, a SQUARER is connected between the oscillator amplifier and the
AMPLITUDE control.
The SQUARER also delivers a TTL-compatible squarewave signal via OUTPUT STAGE II to then.. OUT TTL
socket, regardless of the waveform selected.
The POWER SUPPLY provides a stabilised d.c. voltage for the various circuits.
2. Directions for use
2.1.
INSTALLATION
Before any other connection is made, the protective earth terminal must be connected to a protective
conductor (see section 2.1.3. Earthing).
2.1.1.
Safety Regulations (see IEC 348 or VDE 0411)
Before connecting the instrument to the mains, visually check the cabinet, controls and connectors etc., to
ascertain whether any damage has occurred in transit. If any defects are apparent, do not connect the
instrument to the mains.
Always disconnect the instrument from the mains before removing any protective covers.
Any maintenance and service work necessary with the instrument switched on, should only be performed by
a qualified technician.
The mains connector must only be plugged into an earthed mains socket.
Do not make this safety protection ineffective; for example, by the use of an extension cable without protective
conductor.
