Page 10: Limit Alarms
Isotemp Economy Incubators Page 6 Limit The 500 Series controllers feature a deviation alarm which alerts the Alarms operator and interrupts heater power whenever the actual incubator temperature differs from the set temperature by more than 3 °C. This set limit cannot be adjusted by the operator. -
Page 11: Calibration
Page 7 Isotemp Economy Incubators Calibration The 500 Series controllers are factory calibrated near the center of the incubator’s operating range and will usually remain reasonably accurate over a long period of usage. However, should the accuracy diminish with time, or should the user require greater accuracy at a particular temperature setting, the controller may be recalibrated. - Page 12 Isotemp Economy Incubators Page 8 Carefully remove the temperature dial knob without rotating it. 8. Use a thin blade screwdriver to calibrate Low Adjust. Check thermometer reading. If reading is less than 39 °C, rotate Low Adjust slightly to turn heater off at lower temperature. After each adjustment allow sufficient time for incubator temperature to re- stabilize.
