Relative Δ
When measuring, you can use the relative (Δ) mode to
subtract the offset.
To use relative (Δ) mode, move the blink cursor of menu to Δ
position, and press the ENTER button to enter mode. In this
mode, meter records the presently reading as reference and
shows it on the secondary display. The relative (Δ) mode
subtract reference from each reading, and shows result on the
main display.
In relative (Δ) mode, the minimum range is relative (Δ) range.
For example: The ranges of measuring resistance are 400Ω,
4kΩ, 40kΩ, 400kΩ, 4MΩ, and 40MΩ. If you use the relative
(Δ) mode in 4kΩ range, then the minimum range is the 4kΩ
range. You can use range is 4kΩ to 40MΩ, cannot change to
400Ω.
To exit relative (Δ) mode, press the CANCEL button.
Relative %
When measuring, you can use the relative (%) mode to
calculate the relative percent value. The relative percent
value is define as below:
To use relative (%) mode, move the blink cursor of menu to %
position, and press the ENTER button to enter mode. In this
mode, meter records the presently reading as reference and
shows it on the secondary display. The relative (%) mode
calculate the relative percent value from each reading, and
shows result on the main display.
To exit relative (%) mode, press the CANCEL button.
