LED READOUT DISPLAY:
RH Calibrate RH Alarm Set point
When the toggle switch located on the incubator’s back panel, is placed in
the up position (normal operation), this LED will display actual chamber RH.
Placing the same toggle switch in the down position will display the RH alarm set
point and will also disable the unit’s audible alarm. The LED readout will flash in
the event chamber RH goes below RH set point.
Below the RH LED readout are two, unmarked, potentiometers. The one
on the left is used for calibrating the RH display to correspond with actual
chamber RH, the one on the right is used to set the RH alarm set point.
The RH alarm set point is factory preset at 80% RH and is user adjustable
from 0 to 100% RH. Using insulated Trimmer Pot Tool, Lab-Line #935-021-00,
or equivalent, insert tool into right opening in the control panel. Clockwise turns
increase alarm set point while counterclockwise turns decrease setting.
Note
: toggle switch must be in the
DOWN
position to monitor RH alarm set point.
When calibrating the LED display for actual chamber RH, place an
independent humidity probe in the approximate geometric center of the chamber.
Using a calibrated, digital RH meter, take reading after chamber RH has
stabilized. Adjust left trim pot with Trimmer Pot Tool, if necessary, by rotating
potentiometer slowly either clockwise to increase or counterclockwise to
decrease.
