2.1 Instrument Power-up – Fig. 2.1 and 2.2
Caution. Ensure that all connections, especially to the
earth stud, are made correctly.
a) Check that the input sensors are installed correctly.
b) Check that the pen(s) are installed correctly – see Fig. 2.1.
c) Switch on the supply to the instrument, any power-operated
control circuits and the input signals. Wait for the pens to
settle.
Note. On power-up, the pens are moved to an off-
chart position for automatic referencing. Pen chatter
may occur on those pens nearest the reference
position.
This is a normal function of the instrument.

faceplate 1 when the supply is first switched on.
