2.6. ∆ REL FUNCTION
For an insulation or resistance measurement, it is possible to subtract a reference value from the measured value and display
the difference.
To do this, make a measurement, then press the ∆ REL.
The measurement (Rref) is stored and subtracted from
the present measurement (Rmeas).
The main display changes to zero and the ∆ REL
symbol is displayed.

In insulation measurements, only the digital display is modified by the ∆ REL. The bargraph continues to display the true
measured value.
To exit from the ∆ REL function, it is necessary to press the ∆ REL key again or turn the switch.
2.7. HOLD FUNCTION

HOLD
Pressing the HOLD key freezes the display of the measurement. This can be done in all functions except
voltage in the M Ω setting.
To unfreeze the display, press the
HOLD
key again.
It is not possible to effect a
HOLD
in a timed measurement ( ).
If the measured value is less than the stored value, the display becomes negative.

Pressing the

key displays, in addition, the measured
value as a % of the stored value.
