Setting Steps:
1. Press the [Test] key to enter the <TEST> page or press the [Setup] key to enter the
<Setup> page;
2. Use the cursor key
▼
to move the cursor to the [R-RANGE] field;
3. According to your own needs, use the function keys at the bottom of the screen to
select the desired range method and range. If you select AUTO, the instrument will
automatically select the corresponding best test range name and range; if you select
MANUAL, the instrument will always use the user-specified range for testing; INC +
means increase the range, while the range is changed to lock; DEC - means decrease
the range, and the range is changed to lock at the same time.
When the range is automatic, the instrument will predict the range in each
measurement period, so the test speed will be slightly slower than the locked range.
Moreover, in the case of automatic measurement, frequently changing the range will slow
down the response. Usually when the instrument is used as a sorting measurement, the
automatic range mode is not suitable. For sorting measurement, it is recommended to
select manual range mode.
