DISPLAY
11. Internal Graticule-Eliminates parallax. Risetime.
amplitude and measurement pOints are indicated at the
left-hand graticule edge. c,
12. BEAM FINDER-Compresses the display to within
the graticule area independently of display position or
applied signals and provides a visible viewing level.
13. INTENSITY-Controls brightness of the crt dis-
play.
14.
FOCUS-Adjusts for optimum display definition .
15.
SCALE ILLUM-Controls graticule illumination.
16. ASTIG-Used in conjunction with the FOCUS
cont r ol to obtain a well-defined display . It does not require
readjustment in normal use.
17.
TRACE ROTATION-Adjusts trace to align with
the horizontal graticule lines.
DM44
18. Input Connectors-Two banana jacks provide +
(red) and COM (black) inputs for voltage and resistance
only.
19. Probe Connector-Input connector for the
temperature probe .
20. Readout-Negative polarity indication is
automatic for negative dc voltage and temperature with no
polarity indication for positive measurement. A blinking
display indicates overrange. The decimal point is position-
ed by the FUNCTION and RANGE controls for multimeter
operation and by the oscilloscope A TIME/DIV switch in
the
TIME or 1/TIME modes.
21.
RANGE-Selects from .2 V to 1.2 kV dc in 5 ranges
(1200 volts is the maximum safe input in the 1.2 kV dc
mode); from 200 ohms to 20 megohms in 6 ranges.
22.
FUNCTION-Selects VOL TS. OHMS . TEMP (QC).
1ITIME. or TIME functions of the DM44.
23.
Scale Factor Lamps-Two lamps.
In the TIME function . the Readout and Scale Factor
Lamps indicate the time difference between the two
intensified zones on the crt display . One lamp or the other
will light to indicate ms or f..lS . No lamp lit indicates
seconds.
In the 1/TIME function the Readout and Scale Factor
Lamps indicate the number of measured intervals per unit
of time. One lamp or the other will light to indicate intervals
per ms (1/ms lamp) or intervals per f..lS (1/f..ls lamp). No
