1-16 Getting Started
Status and error messages
Status and error messages are displayed momentarily. During SourceMeter operation and
programming, you will encounter a number of front panel messages. Typical messages are
either status or error in nature and are listed in Appendix B.
Remote display programming
The display can also be controlled by various SCPI :DISPlay subsystem commands.
Table 1-2 summarizes basic commands. See :DISPlay subsystem in Section 17 for more infor-
mation on using these commands and also Disabling front panel display later in this section.
Front panel tests
Use the TEST/DISPLAY TESTS selection of the main MENU to test various aspects of the
front panel. Test selections include:
• KEYS — Front panel keys are tested. Pressing a key displays a message that identifies
that key. Pressing EXIT twice cancels this test.
• DISPLAY PATTERNS — Use this selection to turn on all display pixels and annuncia-
tors. Subsequent key presses cycle through tests that turn off annunciators and corner
pixels of each digit, turn on the rows of the top-left display digit, and turn on all annun-
ciators and pixels of each digit in a sequential manner. Press EXIT to cancel this test.
• CHAR SET — This test displays special characters. Press EXIT to cancel the test.
See Menus later in this section for more menu information.
Disabling front panel display
Front panel display circuitry can be disabled to allow the instrument to operate at a higher
speed. While disabled, the display is frozen with the following message:
FRONT PANEL DISABLED
Press LOCAL to resume.
As reported by the message, all front panel controls (except LOCAL, TRIG, and OUTPUT
ON/OFF) are disabled.
