7.5. HOLD FUNCTION
The HOLD function freezes the currently indicated measured value to allow you to read or record it
easily.
Before measurement, ensure that this function is deactivated before the test starts.
Otherwise, the measurement will be incorrect!
To switch on the Hold function, push the “HOLD” button (8); a signal sound con
fi
rms this command and
“HOLD” appears on the display.
Push the button “HOLD” to deactivate the HOLD function.
7.6. REL-FUNCTION
The REL function permits reference measurements to display component deviations in %. The devia-
tion from the reference value is displayed in percent in the subdisplay. For this, the current display
value is saved and used for further calculation. The calculation formula is:
(measured value – refer-
ence value) / (reference value / 100)
.
- Push the “REL” button to activate this function and save the current measured value. A signal sounds
and the display shows “REL”.
- Start surveying the components. The current measured value is displayed in the main display and the
deviation in % in the subdisplay.
- Pushing “REL” again switches the reference display. A signal sounds and “REL”
fl
ashes in the display.
The main display shows the previously stored reference value and the subdisplay shows the value of
the deviation in %. Every push of the button “REL” switches between the two displays “Measured value”
and “Reference value”.
- To switch off this function, keep the button “REL” pushed for about 2 seconds until a signal sounds and
the “REL” symbol goes out.
The range of the percentage display ranges from -99.9% to 99.9%. When the measured
value is more than twice the reference value, “OL.” is displayed in the subdisplay.
The bar chart display always refers to the current measured value.
