2.5 Installing and Removing Pens

The recorder already comes with the two pens installed. While the unit is turned
off, open the recorder door and remove the pen caps from the two pens. Place
the pen caps in a secure location for reuse.

2.5.1 Installing the Pens

The recorder uses two different colored pens to record information. The
red (upper) pen records temperature. The blue (lower) pen records relative
humidity. Pen life varies with use and climate. Under normal operating
conditions, pens last at least one month. We recommend that you install a fresh
set of pens after every month of use.
