2.1.3.3 Viewing Alarms
When the measurement is below a low alarm threshold or above a high alarm threshold, the instrument emits a continuous
audible signal and the LCD indicates the threshold crossed:

When checking continuity, this enables you to determine whether or not the continuity measurement is less than 2Ω simply
by listening, without looking at the display. You can similarly check insulation quality.
2.1.4 ∆REL Function
For an insulation, resistance, or capacitance measurement, you can configure the instrument to subtract a
reference value from the measured value and display the difference.
To activate this function, take a measurement, and then press the ∆REL button. This measurement becomes
the reference (Rref) and will be stored and subtracted from subsequent measurement values (Rmeas). The
