2 SETTING UP
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.
d) The start-up sequence shown in Fig. 2.2 is displayed on
faceplate 1 when the supply is first switched on.

Note. If the true time line event option is fitted, the
violet event pen records on the same time line as
the red pen, but on the outer edge of the chart.
