CHANGE OF UNIT ΜM/MIL
Display of the readings is factory preset to the unit which is common for the user (generally in μm). To change
the unit from μm to mil or vice versa, place the gauge on any surface or simply take a measurement. While
holding it placed, press the button for at least 3 seconds. The display will switch from one unit to the other.

ZERO-ADJUSTMENT
A new zero-adjustment is required when using the gauge for the first time, working with different materials,
and after inserting a new battery. Place the gauge on one of the zero plates in the case. For the Fe-probe please
take the steel plate; for the NFe-probe take the aluminum plate, when you want
to measure on aluminum; or use a suitable uncoated Fe- or NFe-substrate. Please make sure the probe is placed
perpendicular and evenly on the surface of the zero plate or on your uncoated substrate. If the value
indicated is not within the basic tolerance, the gauge should be adjusted as follows:
Place the gauge on the zero plate (substrate). Then press the button once. On the display a control number
appears and a beep sounds. Then lift off the gauge at least 10 cm (4 inches) from the zero plate (substrate). A
beep sounds and another control number appears. Now the zero-adjustment is completed.
When repeating measurements on the same spot, the reading may not always be 0 μm or 0.00 mil, as the
surface roughness, dirt, scratches etc. might cause variances.

HANDLING
Place the gauge evenly on the object to be tested. The reading is immediately shown on the display
accompanied by a beep. Simultaneously you will also receive the information, which measuring method, Fe or
NFe, is presently used in the gauge (important for gauges with Dual-Probe).
If the gauge was placed incorrectly or lifted off before termination of the measurement, or when being zeroed
on a non-metallic substrate, an error message “Err“ is displayed. Readings that exceed the measuring
range are indicated by the message “IΙFI” (infinite).
The gauge switches on automatically when being placed on the surface and turns off automatically after about
10 seconds when no other measurement is taken. For measurements on rods or tubes etc. align the
“V”-groove along the axis of the object to be tested.

MEASUREMENTS WITH THE DUAL-PROBE
The
QuaNix®4500
gauge combines both measuring methods for Fe and NFe in one probe. Switching from Fe
to NFe or vice versa is done as follows:
Switch on the gauge. The current measuring method is displayed on the left side of the LCD (e.g. Fe). Press the
button for at least 3 seconds. The new measuring method is shown on the left side of the LCD (e.g. NFe).
