- The test result has to be checked by exchanging
the two test electrodes. The opposite direction
of rotation must be displayed.
Note:
If „change" and „Err" is displayed, the switch from
one phase to another with the handle was faulty
(due to slipping). The test has to be repeated.
4.7. Testing of Resistance and Continuity
When the instrument is switched on, press button
"OL" and "MΩ" appear on the display.
Establish firm contact between the measuring
points and the test electrodes.
For resistance values from 0.00 ...1.99 kΩ ,
the measured value is indicated in "kΩ".
The green LED "Ω" lights up at the same time and
an acoustic signal is generated.
For resistance values from 2.0 kΩ ... 999 kΩ,
the measured value is indicated in "kΩ".
The green LED "Ω" flashes at the same time and no
acoustic signal is generated.
For resistance values > 1 MΩ,
the display changes to overflow and "OL" and "MΩ"
appear on the display.
The LED "Ω" does not light up and no acoustic
signal is generated.
Function to "hold" Measured Values (HOLD)
As long as you keep button
can retain the latest measured resistance value on
the display.
Zero Balancing
The zero point in the resistance measuring range
can be recalibrated if necessary:
Hold the test electrodes together and press and
hold button until „CAL" is dislayed.
Ω / V
The electrodes must be held together until the timer
has counted down. Calibration has been carried out
sucessfully if "0,00 kΩ" is indicated and the LED "Ω"
lights up.
Note: During continuity tests, the plus pole of the
measuring voltage is located at the test electrode
designated with +L2. If a voltage of 12 V or more is
applied in this operating mode, the device switches
automatically to voltage testing.
5. Test Point Illumination
The METRAVOLT VT 1500 is equipped with a test
point illumination.
Before measuring, press button
light on or off.
Note: This function is not available for continuity
tests.
