3. Unpacking the Barograph
After taking the barograph out of it’s packaging, remove the surrounding paper, including the carrier-
handle cardboard wrap.
Warning: Be sure to remove all accessories (chart paper, fiber-pens, battery, and clock -
work key) from the package before discarding it.
To open the housing, move the housing lock (13) to the left and raise the lid. For models 225/227
move the housing lock to the left and right.
In models 225 and 227 (Navigator’s Choice) both sides of the housing can be opened.
The barographs are initially set to transport mode. The housing is locked and the transmission system
is decoupled in two places. (This does not apply to the 2X7 series with vibration-damped measuring
systems). The pen-arm is also secured to the disengaging rod with a circular cardboard clip.
Before starting the barograph, the transmission system must be reconnected as shown, and the write-
arm must be removed from the cardboard clip.
