Maintenance and Adjustments
The factory offers a maintenance and calibration service for the 1072. This
service should be performed annually. Alternatively, most wearable parts can
be replaced by the user.
To access the serviceable parts inside the hygrometer, the 1072 panel must be
removed from the carrying case.
Hygrometer Disassembly and Assembly
WARNING: Unplug the 1072 from power before disassembly. Even with the
power switch off, voltages are present inside the unit.
Slide the sample tubing off of the front panel elbow.
Remove the 5 screws along the perimeter of the panel holding it in the case.
Use the sample tubing elbow to help lift the panel straight up and out of the
case.
When re-assembling the panel into the case, make sure sensor cable wires are
tucked in and not pinched under the panel as you lower it into the case.
Install the 5 mounting screws, taking care not to cross thread the screws as you
proceed. The screws only need to be snug to the panel, do not overtighten!
