ARE THEY ALL WORKING?
YOU COULD BREAK THE CIRCUIT AND PUT IN A METER...BUT THAT EXTRA RESISTANCE
CORRUPTS THE MEASUREMENT. THEN YOU HAVE TO REPEAT IT FOR EVERY
BATTERY.
WITH A DC CURRENT PROBE, YOU JUST SNAP IT AROUOND THE WIRE AND READ
THE VALUE.

THIS TDS-540 OSCILLOSCOPE HAS BEEN RAISED FROM THE DEAD.
IT WAS CONSTRUCTED FROM PARTS OF SEVERAL INSTRUMENTS.
IT HAS NO SERIAL NUMBER.
IT IS NOT SUPPORTED BY TEKTRONIX
IN ANY WAY.
SINCE IT'S PAST LONG-TERM SUPPORT, EVEN IF YOU
PAID THE GOING RATE OF ~$7,000
FROM A USED EQUIPMENT
DEALER, IT STILL
WOULDN'T BE SUPPORTED BY TEK.
THIS FAMILY OF SCOPES HAS A CATASTROPHIC FAILURE MODE
DUE TO LEAKY ELECTROLYTIC CAPACITORS.
THIS UNIT HAS HAD ALL (~100) OF THE LEAKY
CAPS REPLACED
AND THE BOARDS CLEANED OF ELECTROLYTE.
IT HAS BEEN UNPROFESSIONALLY RESTORED AND
UNPROFESSIONALLY CALIBRATED USING REFERENCES WITH
EXPIRED CAL STICKERS. MY 5-1/2 DIGIT VOLTMETER OUGHT TO
BE CLOSE ENOUGH TO CALIBRATE AN 8-BIT DIGITIZER.
THE ERROR LOG IS EMPTY.
I BELIEVE IT TO BE FULLY OPERATIONAL AND CALIBRATED,
BUT I'M NOT A CERTIFIED CAL FACILITY.
IT'S SOLD AS-IS.
IF YOU'RE IN AN ENVIRONMENT THAT REQUIRES A CURRENT
CALIBRATION STICKER, YOU SHOULD PAY THE $7,000 AND GET
ONE FROM TUCKER.
IF YOU JUST WANT THE SCOPE YOU'VE ONLY DREAMED OF
TO DO AMAZING THINGS IN YOUR LAB,
THIS ONE'S IS FOR YOU.
