Testo 310 Residential Combustion Analyzer- NO PRINTER
AS IS. SELLING FOR PARTS ONLY. E4 Error.
***THIS WAS A RETURNED ITEM. THE BUYER SAID THIS WAS THE REASON FOR RETURNING IT:
"I charged the analyzer and powered it on and it goes into calibration mode and is supposed to turn on the pump and count down from 30 to zero at which time the calibration is done. What it is doing is counting down to five then starting over at 30 a few times before displaying an E4 error which indicates that the O2 sensor is worn out. I have tried to restart it to calibrate it a few times with the same result, an E4 error code."
IT COMES WITH WHAT'S SHOWN IN THE PHOTOS.
