4.6.2 Measurement Ranging
4-31
During the operation of the current measurement auto range, measurement is made while the limiter
is changed to a value that is larger than the full scale of the measurement range.
•
In the case of *1, range change occurs because the result measured in the 320 mA range is 1 mA.
The result of the range change is that the range becomes the 32 mA range, and the limiter is
changed to the maximum value (32.5 mA) of the 32 mA range.
•
In the case of *2, range change occurs because the result measured in the 32 mA range is 1 mA,
and the limiter is changed to 3.25 mA.
•
In the case of *3, measurement is made in the 3.2 mA range and measurement data of 1 mA is
output.
•
At the y point, the output current should change to 100 mA, but because the limiter is set to 3.25
mA, the output current is held at 3.25 mA.
•
In the case of *5, if measurement is made in the 3.2 mA range, the measurement becomes 3.25
mA. This becomes over range (over 3.2 mA) and range change occurs.
The result of the range change is that the range becomes the 32 mA range, and the limiter is also
changed to the 32.5 mA.
•
In the case of *6, the result measured in the 32 mA range becomes 32.5 mA. Range change fol-
lows because this is over range.
The result of the range change is that the range becomes the 320 mA range, but this becomes the
200 mA compliance set for this range.
•
In the case of *7, the result measured in the 320 mA range becomes 100 mA which is output as
output data.
