Megalodon software problem help needed!

tecdivertraining · 25th February 2007, 02:47

Hi All

I have a student taking a meg course and we have a problem with his secondary handset. During calibration the handset reads the correct Mv in air and then reads the correct Mv on O2, once the data is saved it reverts back to po2 display but reads 21% instead of 98% the three readouts are now frozen, as anyone any ideas on what could cause this?

Thanks

What is the battery voltage? Are the sensor contacts all solid? Do the voltages change when you wiggle the contacts?
I am just throwing out guesses here until someone way smarter comes along but I think it is more likely a mechanical/voltage issue than a software issue.

SensorsMv change when O2 blown through head, Battery Mv 7.1, tried with new batterys, -+& fine only the three po2 are frozen.

double check Hud is not reading correct it reads .21 8 blinks red, even when o2 is flushed through.

cheers

When O2 is flushed what mv reading are you getting. What % of O2 have you set it to calibrate to?

Matt,
It sounds to me to be software problem as the cells are wired in to both hand sets, so if the primary is reading fine then the secondary must have a fault.

The best course of action would be to call Steve at ISC and explain the problem to him.
