Notes:
1)
Use only electronic test equipment with calibrations traceable to NIST standards.
2)
Refer to the DTS-2077 User’s Guide for general operating instructions.
3)
For all measurements using the DTS-2077, the system’s cover should be installed and
the system should be allowed to warm-up at least 15 minutes.
4)
All calibration operations should be made at a grounded workstation while wearing
a grounded strap.

Removal of the System Top and Bottom Covers
(1-1)
Place the system on a sturdy horizontal surface such as a workbench. The system should
be resting on all four feet. Verify the AC power cord is not connected at this time.
(1-2)
Using the Hex wrench, remove (3) screws from the left and (3) screws from the right side
panels. Then remove (15) screws from the top side.
(1-3)
While slightly spreading the side panels from the bottom, lift the cover straight up until
clear of the system. Store cover and screws in a safe place.
(1-4)
Turn DTS system over, so the top is resting on the workbench, and the bottom cover is
facing up.
