CARE OF PENS
4.3.1
V-Type Pens
Occasionally wash out pens with clean hot water or alcohol.
If the pen fails to touch the chart paper due to insufficient tension on pen arm, bend the pen
arm slightly toward the chart so that the pen bears lightly against the chart.
4.3.2
Fiber-Tip Pens
Remove any dust and paper particles that may accumulate at the pen tip. This will ensure low
ink consumption. Under most conditions the pen will provide a continuous record for more
than two months.
