Battery channel connections for 500 mA current verification tests
2. Select the multimeter DC volts measuring function, and enable auto range.
3. Press
the
or keys to select Channel
#1
.
Select the 500 mA readback range and actual
current reading data.
4. Turn on the output.
5. Verify 500 mA range current readback accuracy for the currents listed in
Table 12-6
. For
each test point:
• Set the output current to the correct value, as determined from the digital multimeter voltage
reading and 30
Ω
resistance value.
• Allow the reading to settle.
• Verify that the actual current reading is within the limits given in the table.
NOTE
It may not be possible to set the output current to the exact value. In that case,
set the current to the closest possible value, and modify reading limits
accordingly.
