Menus and Screens
Main Menu
RESISTOR PROTECTION - enables or disables protection of resistor denition related screens. This setting
is useful for ensuring that resistor denitions in the Resistor Library do not get inadvertently changed. The
default is OFF.
MEASURE PROTECTION- enables or disables protection of measurement setting screens. This setting is
used for ensuring that timing and digital lter settings do not get inadvertently changed, possibly resulting in
noisy or less accurate measurements. The default is OFF.
TIME/DATE PROTECTION- enables or disables protection of the Time and Date setting screen. The de-
fault is OFF.
Some screens are always protected and have no associated protection setting. An example is the Calibration
Parameters screen, which always requires the correct password before any of the settings can be changed.
5.7.7.2 CALIBRATION (F5)
MAIN MENU | SYSTEM MENU |
The Calibration menu contains functions and settings for testing and maintaining proper performance of the
Super-Thermometer. Refer to Section 9, Calibration, on page 103 for test and calibration instructions.
The following are the Calibration Menu function keys.
5.7.7.2.1 SYSTEM TEST (F1)
MAIN MENU | SYSTEM MENU | CALIBRATION |
The System Test function key is used to perform a system self-test. This tests various components of the
Super-Thermometer and reports the results. If System Test indicates failures, contact the nearest Fluke Autho-
rized Service Center. See Section 9.2, SYSTEM TEST (F1), on page 103 for more information.
5.7.7.2.2 CURRENT TEST (F2)
MAIN MENU | SYSTEM MENU | CALIBRATION |
The Current Test function allows the user to test the accuracy of the sensing current on the front panel input
channels.
See Section 9.3, CURRENT TEST (F2), on page 103 for more information on how to perform a current test.
5.7.7.2.3 RATIO CALIBRATION (F3)
MAIN MENU | SYSTEM MENU | CALIBRATION |
The Ratio Self-Calibration function allows the user to perform a ratio linearity check or calibration. A check
allows the user to verify ratio accuracy without making changes to ratio parameters. Calibration measures the
Super-Thermometer ratios and makes adjustments to the ratio parameters. A check should always be per-
formed after running the ratio self-calibration function to verify that alignment was successful. See Section
9.4, RATIO CALIBRATION (F3), on page 104 for more information.
5.7.7.2.4 RESISTANCE CALIBRATION (F4)
MAIN MENU | SYSTEM MENU | CALIBRATION |
The Resistance Calibration function allows the user to test and calibrate the internal reference resistors. See
Section 9.5, RESISTANCE CALIBRATION (F4), on page 106 for more information.
5.7.7.2.5 CALIBRATION PARAMETERS (F5)
MAIN MENU | SYSTEM MENU | CALIBRATION |
Important: Calibration parameters should not be changed except as part of the Super-Thermometer
calibration procedure performed by a qualied service technician.
