HIGH FREQUENCY CHARGER (ONBOARD)
4. Reset discharge machine and turn the tester ON.
5. When the batteries have been discharging for approximately 60 minutes, set the discharge machine to
function 3 and check battery set voltage. Check voltage every 10 minutes throughout the rest of the test.
As soon as the battery set voltage reaches 0.5 volts above the shut-off point (42.0 volts), use a multim-
eter to measure individual battery voltages. Measure and record the voltage of each battery to the near-
est 0.01 volt. See following NOTE.
NOTE: The tester will shut off automatically when shut-off voltage is reached.
