Relative mode (REL)
The Relative mode (REL) takes the reading on the dis-
play at the time the REL button is pressed and uses it as
a reference value that is deducted from all subsequent
measurements. This can be very helpful in deducting the
resistance of test leads in low ohm measurements.

To use Relative mode manually select the range
for the function.
Depress the REL button to store the reading on the
display. The “REL” indicator will illuminate con-
firming the 270 is in relative mode.
Now when making a measurement the value
stored will be deducted from the actual reading.
To see what the stored value is, depress the REL
button again and the “REL” indicator will flash and
the reading on the display will show the stored
value. Depress the REL button again to return to
REL mode.
To clear or exit relative mode, press and hold the
REL button for approximately two seconds and the
270 will beep and return to normal operation.
