It may be necessary to calibrate the temperature or humidity controllers to
match an independent temperature or humidity sensor. To do so, follow
the next few steps.
1. Suspend an independent, calibrated sensor(s) in the center of the
interior chamber.
2. Allow approximately 30 minutes for the incubator to stabilize.
3. Turn off the main power switch.
4. Wear a grounding wrist strap to avoid damaging any electrical
components.
5. Remove the 982 controller module(s) by
pressing in the four retaining tabs, two
on the right side; two on the left side.
Refer to Figure 4-8. Pull the controller
module out by gently rocking it from
side to side.
6. Looking at the top and right side of
the controller module, locate the red
DIP switches indicated (Figure 4-9).
Use your fingernail, or a small
screwdriver, to turn Off SW2 by
moving the white toggle towards the
front of the module as in the
illustration.
7. Return the controller to its frame and
firmly press the top and bottom of the
bezel until all four locking tabs “click” into place.
