MODEL 8559A INSTALLATION AND OPERATIONVERIFICATION

2-14. Graticule Overlays2-15. To install a graticule overlay:

1Select proper overlay. H P Part Number 5020- 8565 is for H P 180TR display mainframes, H P Part Number 5020-8566 is for H P 181T/TR display mainframes, and H P Part Number 5020-8567 is for H P 182T display mainframes.

2.For H P 180TR and H P 181T/TR mainframes, remove CRT bezel and metallic-mesh contrast filter. Insert proper overlay and replace contrast filter and CRT bezel.

3.For H P l82T mainframes, grasp top portion of CRT bezel and pull straight up. Remove metal- lic-mesh contrast filter and insert proper over- lay and contrast filter. (Either the metallic-mesh contrast filter or a light blue contrast filter may be used.)

4.Slide bezel back into place to retain overlay and filter.

2-16. When the H P 8559A is properly installed in the display mainframe, the interconnections are as listed in Table 2-2.

2-17. Operating Environment

2-18. Temperature. This instrument has been type tested for 95 percent relative humidity at 40°C for five days. The operating environment should be within the following limits:

Temperature	.................... 0 to 55°C
Altitude .........	<4572 meters (15,000 feet)

2-19. Modifications

2-20. A Modification Kit, H P Part Number 00180- 69503, provides materials and information necessary to add Option 807 rear-panel connections to the standard H P 180-series display. Refer to Table 1-3 in Section I. Option 807 is factory-installed in H P 180TR, H P 181T, H P 181TR, and H P 182T main- frames. The modification kit is required for use with other mainframes if all four rear-panel outputs are needed.
