Warning
See section 5.8 Troubleshooting
6. Pass/Fail indicator
In this case the Pass/Fail is set to 100 μΩ
7. Padlock symbol
The lock symbol is shown when the capacitor
is charged prior to a test and when you lock a
test result.
To choose measurement time
In an environment without electrical interference it is
wise to choose the shortest measurement time, which
means that you can get the largest number of meas-
urements on a single battery charge.
Note
The shortest measurement time (0.1 s) is not
suitable in environments with a frequency of
16 2 / 3 Hz.
Tip: Start making three tests with the
shortest measurement time to figure out
if the results vary. If they do not differ
significantly - use 0.1 s for the tests.
To choose I > I min or I = I max
If you want maximum current for the test, choose
I = I max
. The capacitor will be charged to its maxi-
mum and requires much energy from the batteries.
If lower current is sufficient for the measurement,
it is advisable to use the
I > I min
position. In the
