•
Press the central
"MEASURE"
button and keep it pressed by applying a
pressure of about 2.5Kg.
•
Continue to keep the button pressed and wait until the reading will be
stable, settling time is higher for high resistance values.
MEASURING PRECAUTIONS
ATTENTION:
DURING GROUND RESISTANCE MEASURING, if the earth
reference point is faulty or unconnected, indefinite resistivity values may
appear.
IMPORTANT:
If there are devices connected to the mains power supply on
the surface under test, and even power cords or other conductors under a.c.
voltage, problems on the readings may occur, because 50Hz may cause an
interference with the LABEOHM measuring circuit especially when
measuring high resistance values.
In case of doubt disconnect the mains power supply by opening the main
switch.
ALARM PROGRAM
In program mode you can set an audible alarm sounds when the resistance
measurement is below or above a certain threshold.
Hold the key for
"10x"
second to enter in the programming mode
Press the
"10x"
key to advance the cursor.
Press the
"MEASURE"
key to increase the cursor digit.
Press the
"EXIT"
key to exit the programming mode.
