L R M - 10 – U s e r M a n u a l
10
Modes
The LRM-10 instrument features five modes:
Standard mode: Allows taking a resistance measurement and displaying the
reading.
Relative mode: A reference measurement is taken in the standard mode, and
then the instrument is switched to the relative mode by pressing the MODE
button. Taking a second measurement will display the resistance difference
between the two readings.
Example: A measurement was taken in the standard mode (692.8 micro-ohms).
The MODE button was pressed to select the relative mode. A new measurement
was taken. The difference between the previous reading and the new reading is
displayed (209.03 micro-ohm). The value in the red rectangle is the reference
reading, previously taken in the standard mode.
Relative % mode: Similar to the relative mode, the Relative % mode displays the
resistance difference between the two readings, in percentage.
Motor mode: Allows measuring the winding resistance in a very small coil. This
mode increases the output’s duty cycle in order to saturate the measured coil.
OK/X mode: Allows showing the difference between the previous reading taken
in the standard mode, and the new measurement taken in the OK/X mode.
After the reading is taken in the standard mode, press the MODE button until
you reach the OK/X mode, then take a new measurement by pressing the GO
button. If the new reading is lower than the reading from the standard mode,
the LRM-10 displays OK, otherwise, it displays X.
