14. Range Button
Press to change from Autoranging to manual ranging.
Press repeatedly to select the desired range. To return
to Autoranging, press and hold the button until ‘Auto’
appears in the display. The LCD annunciators indicate
the selected range.
15. REL Button
The relative measurement feature allows you to make
measurements relative to a stored reference value. A
reference voltage, current, capacitance, etc. can be
stored and measurements made in comparison to that
value. This feature is usually used to ‘zero’ residual
readings
on
some
ranges
prior
to
taking
measurements. REL does not work on all ranges and
functions. To activate, first observe the reading to be
‘REL’ed’ on the LCD, then press and release the REL
button. The LCD should then indicate ‘zero’. Make the
desired measurements. To de-activate REL, press and
release the REL button again. ‘REL’ appears in the
display when REL is active.
16. AC Voltage LED
This LED lights when the top of the meter is positioned
close to AC voltage. In some cases the LED may not
light, even tho’ AC voltage is present. DO NOT RELY
ON THIS LED TO INDICATE THE PRESENCE OF AC
VOLTAGE. DOING SO MAY RESULT IN INJURY TO
THE USER.
