Statistical analysis

Press the CURSOR DOWN or CURSOR UP keys to return to the previous

LCD display.

Note

If the measuring range is exceeded (overflow of display

range), no statistical analysis will be performed. In this

case, the individual measured values are listed, but no

value for ΔR

MAX

is calculated.

characters can be entered to the information field

at the bottom. See chapter 5.1.1 regarding entry.

4.1.4 Data logger function (min log)(as of firmware version AH)

Select Parameter

If you choose time parameter setting "min log" from the menu,

exactly 30 measured values are automatically stored during the

selected test duration at time intervals between 4 seconds and

2 minutes. This makes data logger operation possible for measur-

ing durations between 2 and 60 minutes. In this case, the residual

time of the current measurement is not indicated in seconds, but

in minutes. While the test is being performed, icon “Stored” is

briefly shown in the display and the yellow signal lamp “Testing ...”

disappears briefly each time a measured value is being stored. If

the signal generator is activated, an acoustic signal sounds addi-

tionally.

In this function, the current test time is stored for each measure-

ment instead of the parameter for the test duration to ensure the

temporal correlation between measured value and time of mea-

surement.

Note

Before the start of each test with data logger as

described in chapter 5.1, select a new device under test

to avoid the measured values being stored successively

within the same DUT.

This considerably facilitates the subsequent evaluation of

the stored measured values.
