MO, OPTIONS.
1*11. Optional features available for the two models are
specified in Table 1-2. The following paragraphs describe
these features which may be built into or combined with
these recorders. Table 1-3 contains the specifications of
the options.
1-12. TIME BASE - OPTION 001.
1-13. Eight speeds from 0.5 sec/in. to 100 sec/in. are avail¬
able for both models in either the X or Y-axis. In the 7045B
model, however, with the addition of the RESPONSE
switch, the selection of the X or Y-axis time base sweep
speed automatically results in the SLOW response of that
selected axis; the other axis is not affected and operates
normally.
(May be ordered only at time of recorder
purchase.) See Figure 1-5.
1-14. EVENT MARKER - ELECTRIC - OPTION 002.
1-15. A remotely controlled event marker, installed at the
top of the Y arm, identifies significant events in a recording
sequence by making an upward deflection in the margin at
the top of the chart paper. See Figure 1-6. The cartridge-
type pen is actuated by a remote contact closure. This
option may be field installed.
