Appendix B Maintenance and Troubleshooting
Operating the instrument

Instrument will not power up

There are several reasons why the instrument may not be powering:
• Check the power source and restart the instrument.
• If the instrument is running on the AC power adapter, verify that the power source
is adequate.
• Verify that the components are secured tightly to the base unit. The instrument will
not power up if it is not properly assembled.
• Unplug the AC power adapter. Remove the battery, and then reconnect the
battery. Plug in the AC power adapter, and then turn the instrument ON.

Can not print test results

Verify the following:
• Verify that the printer cable is properly connected to the instrument. For instruc-
tions on connecting a printer to the base unit, refer to the base unit manual that
shipped with your instrument or upgrade.
• Verify that correct printer is specified for the instrument (see
for the instrument" on page
• Verify that your printer is working properly.
• Verify that the printer is turned on and loaded with paper.

Instrument shows an unused slot

In rare instances, the instrument may show an unused slot. This is more likely to occur
if a MSAM is swapped while the base unit is using AC power but may occur after
upgrading firmware.
If it occurs after upgrading the firmware, 1) hard boot the instrument, 2) power down
and unplug the adapter, then 3) replug the adapter and power up again.
If removing a MSAM, power down the instrument and unplug the AC power adapter.
See "Inserting MSAMs or CSAMs into the 6000A base unit or DMC" on page

Instrument does not recognize USB stick

Do the following:
• Reboot the instrument. Verify that your instrument is OFF, and then unplug the
unit for at least 5 seconds to force a hard boot.
• Reconnect AC power to the instrument.
• Turn ON the instrument.
• Re-insert the USB stick. This should resolve the issue.
