The Use of Relative Value and Relative
Percentage Value Mode
The and % mode applies to all measurement functions,
with auto ranging.
REL mode can be used together with Auto Hold and
MAX MIN mode.
The definition is as follows:
l
Relative value ( ) = present value - stored value
For instance, if the stored value is 20.0V and the
present value is 22.0V, the reading would be 2.0V.
If a new measurement value is equal to the stored
value then display 0.0V.
l
Relative percentage value ( %) =
(relative value stored value) X 100%
To enter or exit and % mode:
l
Use rotary switch to select the desired measurement
function before selecting REL . If measurement
functions change manually after REL is selected,
the Meter exits the REL mode.
l
Press REL to enter mode, and the present
measurement range is locked and display the last
measurement value as "0" as the stored value.
Then if carrying out measurement at this time, the
LCD will display the
value as the result.
l
Press REL again to enter % mode, and the
present measurement range is locked and display
the last measurement value as "0" as the stored
value. Then if carrying out measurement at this
time, the LCD will display the
