The marker-pen element and the cap are 

 made together and may be separated from the 

 inkwell by unscrewing the cap. After filling the 

 inkwell and replacing the pen element, ink 

 should be drawn into the pen in the same manner 

 as was used for the main pen. 



Place the marker pen in its holder on the 

 right side of the meter, making certain that the 

 fork of the pen element is over the actuator 

 bar of the solenoid. Lower the scale plate 

 into position. Swing the pen across the chart 

 several times to make certain that it writes and 

 does not rub the inkwell or scale plate at 

 any position. The indicating target must not 

 touch the scale plate. 



If the writing pen is not exactly on zero, 

 tap the chart in front of the pen to ensure
