ThermoWorks 9150-X HART SCIENTIFIC 9150 THERMOCOUPLE FURNACE - Manual (Page 18)

Fan - The fan inside the calibrator runs continuously when the unit is being op-
erated to provide cooling for the instrument. Slots at the top and sides of the
calibrator are provided for airflow. The area around the calibrator must be kept
clear to allow adequate ventilation. The airflow is directed upward and can be
extremely hot.
6.2 Front Panel
The front panel consists of the controller display and the controller keypad as
shown in Figure 2.
Controller Display - The digital display is an important part of the temperature
controller because it not only displays set and actual temperatures but also dis-
plays various calibrator functions, settings, and constants. The display shows
temperatures in units according to the selected scale °C or °F.
Controller Keypad - The four button keypad allows easy setting of the
set-point temperature. The control buttons (SET, DOWN, UP, and EXIT) are
used to set the calibrator temperature set-point, access and set other operating
parameters, and access and set calibration parameters.
Setting the control temperature is done directly in degrees of the current scale.
It can be set to one-tenth of a degree Celsius or Fahrenheit.
The functions of the buttons are as follows:
SET – Used to display the next parameter in the menu and to store parameters
to the displayed value.
DOWN – Used to decrement the displayed value of parameters.
UP – Used to increment the displayed value.
