Description

Model #: DPI 330

Excess from my Fortune 500 client.  This client periodically upgrades equipment and I resell a lot for them.  Unsure their exact reason for having me sell but I always offer 30 day right of return if needed for their items.
I am not a user of the equipment just an equipment remarketer.  All my listings intend to give the buyer info so they can try to better make an educated purchase.  This item I can only power on and go to various screens and take photos as I have no pressure type item to test it with and I lack the knowledge to do that anyways.
Limiting power on test:  Turned on DPI 330 and it showed version and self test and went on without listing any errors after self test.  I then went into "input" section and changed it to temp and it said 28.7 C and went to Voltage and it said .0001 V and went to current and it showed .000mA.  I loosened collar on P1 and pumped it one cycle and the readout went from 1 PSI up to 4 PSI. Then it rather quickly went back to zero.  I then pumped again and it did same.  Then I tried to tighted and lossen both P1 and P2 and I then had it so I when I tried to pump again to raise again it now didn't hold hte PSI as I untighted the collars in a wrong combination.  I realized I didn't know what I was doing and gave up on that. Can redo it if that helps you learn about it.  I then just went to different screens and did button pushes.  All button pushes seemed to get a result that the instrument was looking for.  Note: when I set the time and date, it would lose it on reboot apparently from dead battery.
In so far as the battery, I couldn't figure it's condition exactly.  It appears to power the calibrator but for a very short period so either the AC adapter needs to be plugged in all the time or the battery replaced (if possible).  Testing: I couldn't get it to turn on via/from the battery from a "cold start".  I plugged it in and it came on and then could stay on for a little while without the ac adapter plugged in but not long enough to use it that way.  I am not sure if it has a battery saver timeout setting.  I will just assume it more likely is a battery issue problem.  Strange thing though is the battery meter on the calibrator does say it is fully charged before it turns off.
An associate of mine owns one of the largest test equipment calibration service companies here in Minneapolis.  He says his charge is typically 0 for this calibration but will give me 35% off and I am willing to offer this discounted 5 price to a buyer here on Ebay.  His lab has always been ISO certified, which I believe it will state on the Cert.  I can have the cert made out on your company name.
If interested in calibration, please don't pay for it until it is ready to be shipping in around a week.  I normally have to ship all sales within one day of payment for my ebay policy standard and so I don't want the week later shipping to ruin my website standards.
So if you want calibration purchase and pay when I tell you it is done in around a week, or pay right away if no calibration is desired.
