Dell XD802 AC Adapter Safety Considerations
UPS's using a single 12 V laptop battery can cause injury. The batteries used can supply large currents if short circuited. It is easy to lose a finger if a ring shorts the battery supply. The risk is that the ring becomes hot, causing cauterisation of the blood vessels. With no blood supply, the only solution is amputation.
The other risks of shorted batteries is the potential for the battery case to split open releasing Dell XD802 AC Adapter (http://www.usadapter.com/Laptop-Dell-Adapter/Dell-XD802-AC-Adapter-19.5V-3.34A.html ) electrolyte, and flying molten metal. The Dell XD802 AC Adapter supply of units in the 2 to 3 kVA range from 48 to 96 V. The 96 V units float the battery bank at 110 V, which will electrocute.
On-line units work at high laptop ac adapter voltages. In Australia, the nominal line Dell voltage is 240 VAC which when rectified, results in power rails of plus and minus 350 VDC. That is a total of some 700 V.
When working on UPS's, the use of an earth leakage circuit breaker/residual current detector, or whatever they are known as in your part of the world, has to be considered mandatory.
Some manufacturers, for cost reasons, do not use line monitoring transformers. Instead, high value resistors are used to divide the line Dell XD802 AC Adapter voltage to a value suitable for the control electronics. This results in a machine that is technically totally live. Keep a watch out for these ones and test before touching.
Be aware that the ground clip of an oscilloscope probe is earth. Depending on wiring rules, earth may be bonded to neutral at the main switch/fuse panel. This is true in Australia. Use an oscilloscope with differential Dell XD802 AC Adapter inputs designed for the job. A suitable alternative is an add on differential input unit in conjunction with a standard scope. The design presented in Elektor Electronics around 1994 works very well and with a bandwidth of 15 MHz, nothing will be missed.
It can not be stressed enough that all UPS's are potential death traps. The line voltage in any country is lethal. Any Dell XD802 AC Adapter voltage higher than around 50 V is considered hazardous. So you should know some laptop ac adapter safety guide, before you buy your Dell ac adapter.

On an oscilloscope, which is a problem in using 2 single-ended probes to make differential measurements?
1. a lower common mode rejection
2. using two times as many scope channels
3. delay or skew differences between 2 separate probes
The main problem is the delay or skew differences which can affect the accuracy of measurment. This might be due to improper calibration or errors in the difference circuit used to provide the differential value.
The other two offered answers are not serious problems.
