subsequent measurements.
1. Press REL button, the meter enters the
Relative mode and stores the present
reading as a reference for subsequent
measurements, and “REL” appears on
the display as an indicator. The display
reads zero.
2. When you perform a new measurement,
the display shows the difference between
the reference and the new measurement.
3. Press REL button again, the meter exits
Relative mode, “REL” disappears.
Manual Ranging and Autoranging
The meter defaults to autorange mode in
measurement functions which have both
autorange mode and manual range mode.
When the meter is in autorange mode,
“AUTO” is displayed.
1. To enter the manual range mode, press
“RANGE” button, the meter enters the
manual range mode, “AUTO“ turns off.
Each press of the “RANGE” button in-
creases the range. When the highest
range is reached, the meter wraps to the

ment with the FUNC button, the display
shows the relevant symbol ( bzw. ).
3. Select autorange mode or manual range
mode with the “RANG” button.
If you use manual range mode and don’t
know the magnitude of the voltage to be
measured beforehand, select the highest
range and then reduce it range by range
until satisfactory resolution is obtained.
4. Connect the test leads across the load to
be measured.
5. Read LCD display. For dc voltage meas-
urement, the polarity of the red lead con-
nection will be indicated as well.

to the meter, do not attempt to measure dc
voltage higher than 250 V or ac voltage high-
er than 250 V rms although readings may be
obtained.
