Fluke 9150 6.2 Front Panel

Fan - The fan inside the calibrator runs continuouslywhen the unit is being op-

erated toprovide cooling for the instrument. Slots at the top and sides of the

calibratorare provided for airflow. The area around the calibrator must be kept

clear to allowadequ ate ventilation.Th ea irflowis directed upward and can be

extremely hot.

6.2 Front Panel

The front panel consistsof the controller display and the controller keypad as

showninFigure2.

ControllerD isplay - The digitaldisplay is an important part of the temperature

controller because it not only displays set and actual temperatures but also dis-

plays variouscalibrator functions, settings, and constants. The display shows

temperatures in units according to the selected scale °C or °F.

ControllerKeypad - The four button keypad allows easy setting of the

set-pointtemperature. The control buttons (SET, DOWN, UP,and EXIT) are

used to set thecalibrator temperature set-point, access and set other operating

parameters, and access and setcalibration p arameters.

Setting the control temperature is done directly in degreesof the current scale.

It can be set to one-tenth of a degreeCelsius or Fahrenheit.

The functionsof the buttons are as follows:

SET – Used to display the nextparameter in the menu and to store parameters

to the displayed value.

DOWN– Used to decrement the displayed value of parameters.

UP –Usedtoincrementthedisplayedvalue.
