10756A Manual Compensator - HP 5501A Operating And Service Manual

3.23 10756A Manual Compensator
The 10756A Manual Compensator i s a small panel and circuit board unit (Figure 3-20) de-
signed to plug directly on the 10755A Compensation Interface. The 10756A has four thumb-
wheel operated switches that allow the calculated compensation factor number to be set. The
four BCD bits from each switch are then inverted and applied to the 10755A Compensation
Interface. For additional information and schematics, refer to the 10756A Manual Compensa-
tor Operating and Service Manual.
3.24 5510A O p t 010 Automatic Compensator and 10563A Material Temperature Sensor
The 5510A Opt 010 Automatic Compensator itself is identical to the standard 5510A Automatic
Compensator. The difference in models is that when used in the 5501A Laser Transducer
System, the following cable changes are made:
a. Delete the 562A-16 Cable.
b.
Add the 59995-61082 lnterface Cable between the 5510A and the 10755A Compensa-
tion Interface;
c. Add the 1074060005 Power Cable between the 10740A Coupler and the +15V power supply.
Overall, the 5510A Opt 010 Automatic Compensator makes atmospheric measurements and the
10563A Material Temperature Sensor makes material temperature measurements and supplies
four BCD compensation digits to the 10755A Compensation Interface. For operating instructions
refer to Section IV, Programming and Operation. For additional information and schematics
refer to the HP 5510A Operating and Service Manual.
3.25 10783A Numeric Display
The 10783A Numeric Display provides the laser transducer system with digital display of
single or multiple-axis displacement data. I t is driven from the Hewlett-Packard lnterface Bus
in either the "Listen Always" mode or the "Addressable" mode.
Fourteen 7-segment LED indicators with left-hand decimal points allow ample capacity for
displaying more than one axis of data. Six axis identifiers (A, B, C, X, Y, Z) are supplied with
each display module and may be inserted into the specially designed front panel. As an ex-
ample, one 10783A can display six digits with sign and decimal point for the X-axis and five
digits with sign and decimal point for the Y-axis, with a space between the two numbers. The
"X" and "Y" identifiers can be placed in the front panel below the appropriate digits.
The characters that can be displayed are the digits 0 to 9 , a minus sign, the letter E and the
decimal point. Front panel indicators include an O N light indicating when the 10783A is
"Addressed" and an overflow light that indicates when more than 14 characters have been
received. I n an overflow condition, the 14-least-significant digits are displayed. I n addition to
these indicators, there is a lamp test switch for checking all segments and indicators not al-
ready energized.
Flicker-free output is obtained by employing both input and output data storage. The display
digits are strobed at a constant rate independent of input data transfer rate.
