I have a thermometer that gives Error 4.8 immediately once it turns on. I have replaced the probe and the well and there was no change. Manual indicates to swap the unit out for another. Anyone have any experience with the error? RE: Welch Allyn - Sure Temp Plus 692
hi guys,
Has anyone encountered the error 4.8 and was able to defeat it somehow?
It says the unit is not calibrated so I am thinking it is basically dead unless in warranty.
I was curious if anyone has ventured to try to resolve the issue somehow though..
Let me know if you have worked into this error if you have looked into it.
I talked to Welch Allyn who tell me they will swap thermometers with me for $162.
Thanks in advance! I am wondering if there is something I can do to bypass this action though, and am looking for any actions you guys have taken along that line.
mrstan! RE: Welch Allyn - Sure Temp Plus 690
I purchased a Welch Allyn Sure Temp Plus 692 digital thermometer for use in a home environment where readings more accurate than one can get from the typical consumer digital thermometers are desired. However, now after trying 3 different units, I am finding that the normal fast reading oral measurements are high by about a full degree F. That is, I can take an oral measurement in normal mode. Then immediately select monitor mode and wait 3 minutes for this calibrated measurement to settle, and the first reading is higher than the second by from 0.8 to 1.2 degrees F. The company only specs measurements in the monitor mode, but that takes way too long for routine use. My other references suggest that the monitor mode is correct within the +- 0.1 Degree C spec. They did replace first the probe and then the unit under warranty when I complained, but the replacement units had the same issue. I cannot pin the company down on whether the design of the fast oral readings is normally that far off, but that seems to be the only conclusion. I know these are widely used in medical facilities. I would expect normal accuracies within at least a few tenths of a degree F. Has anyone had any similar issues? RE: Welch Allyn - Sure Temp Plus 692
