Fluke 9107 - Manual (Page 22)

Power Entry Module (9107) - The power switch is located on the power entry
module (PEM). The PEM also houses the fuses.The supply voltage for the unit
is indicated on the PEM.
Serial Port - This D-9 connector is for interfacing the calibrator to a computer
or terminal with serial RS-232 communications.
Display Hold - The two terminals may be used to wire a switch or cut-out to
the calibrator to trigger the instrument to freeze the displayed well temperature.
Fuse Holders - At the rear of the calibrator are two user accessable fuse

Controller Display - The digital display is an important part of the temperature
controller because it not only displays set and actual temperatures but also vari-
ous calibrator functions, settings, and constants. The display shows tempera-
tures 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-hundredth of a degree Celsius.
The functions of the buttons are as follows:
SET – Used to display the next parameter in the menu and to set parameters to
the displayed value.
DOWN – Used to decrement the displayed value of parameters.
