3.5 The Difference Meter
The Difference Meter is a feature on the DLOR2 that is displayed at the top of the primary screen
(marked ‘1’ on the diagram).
The Difference Meter works in inductive and resistive modes only.
It can be toggled off and on in the instrument settings, giving space for other characters in the primary field to be
displayed in a larger format making them easier to read, if required.
Refer to 9.1 General Settings on page 28.
Repetitive measurements can be easily compared with an initial reference measurement. The Difference Meter
translates percentage difference to a needle / pointer movement making it very easy to see change. The green
marker shows the initial or reference reading. Noisy results are shown with a red marker. Good results are shown
with a blue marker.
When testing, pressing the TICK button (
) sets the latest reading as the reference reading and cancels all other
readings recorded on display, including those on the Difference Meter and the secondary field.
