All checks are make from the 1.006 DISP outside of the instrument. 1.007 DISP If the test is started within a short period after 1.007 DISP switching on, bear in mind that steps may be out of 1.007 DISP specification, due to insufficient warming-up time. 1.007 DISP 1.007 DISP Warming-up time under average conditions is 30 minutes. 1.008 DISP The performance checks are make with a stable, well- 1.008 DISP focussed, low-intensity display. Unless otherwise noted, 1.008 DISP adjust the intensity and trigger-level controls as 1.008 DISP needed. 1.009 HEAD {5.3.4 CRT intensity} 1.010 SET INTENSITY : barely visible 1.011 EVAL Is the {INTENS control approx 10 O'clock position}?
