KISS /Hammerhead

andibk · 21st February 2006, 20:53

I have a Hammerhead on my KISS classic unit. I have been emailing Kevin but haven't been getting a response. Must be out diving or something. When I do a calibration on the unit I am getting a reading that says the number 3 cell has failed. I have tested the sensor and the sensor is good. I have also tried other sensors that are good but I still get a reading saying that this sensor is failed. Has anybody else had this problem? Anybody know what the problem may be? Any help will greatly be appreciated.

What is the Millivolt-reading of the failing sensor in pure O2 if you go to the MV screen??? Less then 40 Mv will not be accepted for calibration.
The reason why its less can of course vary.

Rotate the existing cells around and see if the fault can be isolated. It sounds like you may have cable damage/corrosion etc on your fittings.

Andi,
I would swap around the banana/molex plugs and see if that tranfers the problem. Also carrefully check the wires, especially under the zip ties and around them.

Probably a problem with the connector. I had a similar issue. When I inserted the plug completely the cell failed. When I only plugged it in halfway it worked fine.

Go to your local Radio Shack and get some "Pro Gold".... Typically it's also sold with a special contact cleaner. Follow the directions and spray it on banana contact and into each of the molex's. "Not into the O2 Sensors".

That should help address any contact related issues.

Dive Safe.

Found the problem, thanks to the list. The MV reading on the hammerhead unit was reading below 40 when calibrated on oxygen. Tried another cell and all worked. Thanks

We used to field a bunch of "why doesn't this thing work??" phone calls that were due to a particular sensor being below 40 mV during Calibration. That is, until we changed the "0.00" reading when a cell has been rejected during calibration to "FAIL" - now, if your sensor is below the minimum of 40 mV during calibration, you will see "FAIL" on the main screen for that particular cell, letting you know that you should either re-do your calibration routine (making sure you are in as close to 100% O2 as possible) or replace the faulty cell.

Saved me some shipping from customers who SWORE they had really calibrated in 100% too...

That's good to know, both what the issue was and the fix

so 0.00 means a bad connection and fail means below 40 mV.
