a detachable 3-wire power cable.
Proceed as follows
for installation.
a.
Connect plug (3-socket connector) to ac line
jack at rear of instrument.
b.
Connect plug (2-blade with round grounding
pin) to 3-wire (grounded) power outlet.
Exposed
portions of instrument are grounded through the
round pin on the plug for safety; when only 2-blade
outlet is available, use connector adapter (HP Part
No. 1251-0048), then connect short wire from side of
adapter to ground.
2-13. REMOTE PROGRAMMING, OPTION 002
2-14. The following paragraphs describe remote pro¬
gramming requirements for the counter with Option
002. See Paragraph 2-33 for Option 004 programming.

mable:
a.
FUNCTION
b.
TIME BASE/MULTIPLIER
c.
CHECK function
d.
SLOPE

2-17.
The following front-panel controls are NOT
programmable:
a.
AC/DC
b.
SEP-COM
c.
FAST/NORM
d.
ATTEN
2-18. The trigger level controls may be remotely pro¬
grammed or the front-panel LEVEL controls may be
used.
It is possible to program the LEVEL controls
without programming the remainder of the front-
panel controls.
When remote programming is used,
the LEVEL controls must be set to PRESET. Display
time may be remotely programmed and/or the front-
panel controls may be used.
2-19. Remote Programming Requirements
2-20.
All lines may be controlled by TTL or DTL
signals or contact closure to ground when the unit is
being remotely programmed: except the trigger levels
which are programmed by an analog level (if pro¬
grammed) and the display time line (Hold), J10 pin
35, which should NOT be pulled up to +5 V by less
than 200Q while programming.
2-21.
When the unit is NOT being programmed (Ext
line high), all the lines should be left open or pulled up
to +5 V by not less than 5kO, except the trigger levels,
which should be open circuited.
2-22. Remote Programming Procedure
2-23.
In order to remotely program the counter, the
following must be done:
a. Set FUNCTION switch to any function but
START or STOP.
b.
Ground the EXT line at rear-panel REMOTE
PROGRAM connector J 10(17).
This disables the
front panel switches. Ground is available at J 10(36).
c.
Select the desired function.
d.
Select the desired time base.
e.
Select the slope (+ or -) for CHANNEL A and
B. This is accomplished by grounding the Slope line
for (-) and leaving it open for (+).
Slope A line is
J10(28). Slope B line is J 10(29).
f.
Select the trigger level for input signal.
g.
Adjust the display time.
h. Manual reset is available by grounding (<.7 V)
pin 34. Check is available by grounding pin 14.
