    The display of the calibrator is shown in Figure 3. The menu bar is used to setup the display to perform the desired function. Table 3 explains the different parts of the display: Table 3: Display Functions Name Description Primary Parameters Determine what parameter is going to be measured or sourced.
  • Page 9 [DONE] returns to home menu. Contrast is adjusted using the arrow options, which are available after choosing [CONTRAST]. NOTE: The PTC8010 calibrator offers a wide range contrast adjustment feature to accommodate operation in extreme temperatures. In certain cases making large changes in contrast may render the display difficult to read under normal conditions.
  • Page 10 The parameter selection menu is called up when [CONFIG] is selected from the main menu. It contains the following options: [SELECT], [NEXT], and [DONE]. When the display is selected, a parameter will start to flash. Use the [SELECT] option to change the parameter, and the [NEXT] option to switch to another variable.

  • Page 18: Changing Between Remote And Local Operation

    5.2 Changing Between Remote and Local Operation There are three modes of operation of the calibrator, Local, Remote, and Remote with Lockout. Local mode is the default mode. Commands may be entered using the keypad on the unit or using a computer. In Remote mode the keypad is disabled, and commands may only be entered using a computer, but choosing [GO TO LOCAL] from the menu on the calibrator display will restore keypad operation.
