|---|---|---|
| FTLD | FUNCTIONAL DESCRIPTION | ADJUST LEVEL OF MERCURY POOL SO ITS SURFACE JUST TOUCHES THE WHITE ZERO POINTER WHICH FIXES ZERO POINT OF COLUMN; USE SCALE AND VERNIER TO READ COLUMN HEIGHT; MAKE CORRECTIONS FOR TEMP AND GRAVITY AS SHOWN IN INSTRUCTIONS, THIS WILL GIVE TRUE BAROMETRIC PRESSURE AT DESIRED LOCATION |
| ABMK | OVERALL WIDTH | 3.000 INCHES NOMINAL |
| FEAT | SPECIAL FEATURES | CAN BE USED UP TO 3000 FT, 900 M, ABOVE SEA LEVEL; DOUBLE SCALE ALSO READS 647 TO 805 MM AT 0.1 MM DIV; DOUBLE SCALED THERMOMETER READS IN C AND F; MERCURY LEVEL AND WHITE ZERO POINTER ARE CLEARLY VISIBLE IN GLASS CISTERN; WHITE BACKING FOR CISTERN AND MENISCUS; UNIFORM BORE 1/4 INCH, 6.4 MM, SO CAPILLARY DEPRESSION IS CONSTANT AND TAKEN INTO ACCOUNT IN CALIBRATION; TUBE IS IN METAL CASING ON 3 BY 42 INCH WOOD PANEL; MERCURY IS INCLUDED |
