Serial Port - A three-conductor jack is present for interfacing the calibrator to
a computer or terminal with serial RS-232 communications.
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. The High Temp and Low
Temp displays are labeled.
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. The High Temp and Low
Temp controllers each have their own set of buttons.
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–Usedtoincrementthedisplayedvalue.
EXIT – Used to exit a function and skip to the next function. Any changes
made to the displayed value are ignored.
5.2 Constant Temperature Block Assembly
5.2.1 Constant Temperature Block
The high temperature “Block” is made of bronze and the cold temperature
“Block” is made of aluminum. The “Block” provides a constant and accurate
temperature environment for the sensor that is to be calibrated (see Figure 2). A
0.5” diameter well is provided that may be used for sensors of that size or may
be sleeved down with various sized probe sleeves. Heaters are strategically
placed in the block assembly to provide even heat to the sensor. A high-temper
-
ature platinum control RTD is imbedded at the base of the block assembly to
sense and control the temperature of the block. The entire assembly is sus
-
pended in an air cooled chamber thermally isolated from the chassis and
electronics.
WARNING: The block vent cover may be very hot due to the fan blowing
upward.
