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
% value as the result.
l Press REL
again or turn the rotary switch to reset
the stored value and exit
% and
mode, returning
to normal measurement mode.
