This is what the Multitester looks like:
Figure 10: Multitester Instrument. Use it to monitor the battery voltage while applying a
load or charge current, plus other functions.
With a battery connected, if the Multitester says 0V (zero volts) then check the connection to your battery – it should be
connected to channel one with the correct polarity.
For this test don’t use a battery pack that has any protection circuitry inside that might interfere with the testing. You
can test those batteries once you are comfortable using the UBA.
For this example, I am using a four cell 600mAh NiCd battery.
Enter a small test current (100mA for example) into the load or charge current edit boxes and click the corresponding
Set button. The battery voltage should rise a bit if you set a charge current or drop a bit if you set a load current. This
verifies that the UBA charger and load are functioning and that you have a good connection to the battery. Note, you
can’t run the load and the charger at the same time.
Besides applying a load or charge current, the Multitester can also do a constant voltage charge, a quick test
(measures battery internal resistance), or read the UBA temperature probes (if connected). Press F1 for more
information from the online help. Experiment with some of the options.
Warning: The Multitester does not check the suitability of the charge or load current that you are using. Unless you
know your battery’s condition, you should limit the charge and load current to just a few seconds so you don’t damage
it.
Close the Multitester window so that you can start a battery analyzer on that channel: it is not possible to run two
instruments on the same channel at the same time.
