angle indicators when hoisting the Nansen cast. 

 Signal the winch operator when the indicator 

 is in sight and again when it is at the mrfaee 

 of the water. When the indicator is at platform 

 level, clieck the UP meter wheel reading and 

 record it, connect the safety line to rod (A) on 

 the indicator, and remove the tripping messen- 

 ger and indicator from the wire. 



E-9 Reading the Wire Angle Indicator.— 



To read the wire angle indicator hold the instru- 



ment at eye level and read the wire angle direct- 

 ly from the zero to 90° scale. A line scribed on 

 the plastic case that encloses the angle indica- 

 tor and compass is the horizontal reference line 

 for the angle indicator. Enter the wire angle in 

 the Therm. No. column. The direction the wire 

 was tending at the time the indicator was 

 tripped can be read directly from the compass. 

 Enter this direction under the wire angle read- 

 ing in the Tlienn. No. column ; e.g., DR 210°.
