Taking Relative Measurement

The meter allows you to take measurements with zero offset or other values as
reference using the REL
Use zero offset as reference
1. Set the meter to any function e�cept ºC/ºF, dBm, ,
2. Disconnect test leads for capacitance, or touch the test leads together for
other functions to measure zero offset.
3. when you see the reading, hold down REL
4. Take a measurement. You will get the actual �alue of the measured
component.

Use baseline as reference
1. Set the meter to any function e�cept ºC/ºF, dBm, ,
2. press RANGE to select a suitable range for relati�e measurement if necessary.
3. Connect the test leads to the component whose measurement you want to
use as a baseline.
4. when you see the reading, hold down REL
to manual range.
5. Take a measurement. You will get the relati�e �alue of the measured
component to the baseline. if the measured �alue is lower than baseline, the
meter will show a negati�e relati�e �alue.
To reset a relati�e measurement, press REL
another setting.

Displaying Temperature

You can use an optional thermocouple module (not supplied) to measure
temperature with your meter.
WARNING: Do �OT use the thermocouple to measure objects when the �oltage
is abo�e 30 V RMS and 42.4 V peak or 60V DC.
1. Set the function dial to ºC/ºF/
2. Unplug both test leads from the meter, plug the thermocouple's common
plug into –COM (common), then plug the thermocouple's +V plug into
+ V.mA.Ω.
3. press SELECT to select temperature measurement. Then press RANGE to to
toggle between Celsius and Fahrenheit,
4. Touch the thermocouple's sensor head to the object you want to test.
