Condition & Testing Notes
Used - Power Tested Only. This unit has been plugged in and successfully powers on, and the front red LED digital display illuminates brightly and clearly without issue. However, we do not have the specialized engineering expertise or laboratory equipment to fully test its signal inputs or verify its calibration. Because of this, we cannot guarantee full functionality. We are selling it exactly as shown, but we do allow returns if the unit does not meet your satisfaction!
Cosmetically, the unit remains in good, structurally sound condition, exhibiting typical wear expected from age and standard lab use. You will notice some peeling and wear on the top instructional reference sticker. Please review the attached photos closely to see the exact cosmetic condition, the screen readout, and the rear port layout.
