If the gauge is not used for a long period, please remove the batteries

from the gauge in order to prevent leakage that could damage the unit.

In case of a malfunction of the instrument please do not try to repair it on

your own. Our customer service will be happy to assist you.

Starting up and changing batteries

The gauge is powered by two AA batteries alkaline. Instead, two

rechargeable AA batteries with 1.2V each can be used. Please note that

rechargeable batteries have a significantly lower capacity.

Low battery power is indicated in three steps:

Step 1:

Change of batteries is advised. However, several

measurements can still be taken until the gauge

shuts off. Backlight is on.

Step 2:

(small symbol) Measurements are still possible.

Backlight is off.

Step 3:

(large symbol in the middle of the display)

Measurements are no longer possible.

Note! Empty batteries should be disposed of properly. If possible, please

use the appropriate method.

Zero-Adjustment

A zero-adjustment is required when using the gauge for the first time or

after inserting new batteries, when working with different materials or from,

time to time. (e.g. when the ambient temperature changes). We strictly

recommend carrying out the reference check on the uncoated original

substrate in order to adjust for possible geometric or surface specific cha-

racteristics (ref. Technical Data). If this is not possible, please use the zero-

reference plates supplied with the case. Place the gauge on one of the

zero plates in the case. For the Fe-probe please use the steel plate; for the

NFe-probe use the aluminum plate, if you want to measure on aluminum;

or use a suitable uncoated Fe- or NFe-substrate.

Please make sure the probe is switched to the correct measuring mode

during zero-adjustment. Otherwise false measurements might occur.

Please make sure the probe tip is placed perpendicularly and evenly on

the surface . If measuring on a cylindrical body, you can use the v-groove

to ensure the position. If the value indicated is not within the range of the

accuracy, adjust the gauge as follows: Place the gauge on the zero plate

(substrate). Then press the button once. A control number appears on the

display and an acoustic signal sounds. Now lift off the gauge at least

10 cm (4 inches) from the zero plate (substrate). The acoustic signal

sounds again and another control number appears. The zero-adjustment

is completed.

When repeating measurements on the same spot, the reading may not

always be 0 µm or 0.00 mil, since surface roughness, dirt, scratches etc.

might cause variances.

Handling

Place the gauge evenly on the spot to be tested. Take care that the ring-

like bearing area connects completely with the measuring area around the

measuring probe. Use the grips near the measurement head to ensure pro-

per placement. The display immediately shows the reading accompanied

by an acoustic signal.

Together with the measuring result you will also receive information on

what probe, Fe or NFe, the gauge used. This is particularly important when

using the Dual-Probe.

When being zeroed on a non-metallic substrate or when operated in the

wrong way a "Zero Reference Error" appears. Readings exceeding the

measuring range are indicated with „INFI" (infinite) if the substrate has

been selected as fixed. If substrate selection is enabled, the gauge will

switch the substrate. The gauge switches on automatically when placed

on a surface and turns off when not in use for about 30 seconds.

The v-groove on the measuring tip helps measuring on rods or tubes etc.

Setting the measuring mode or unit (μm or mil)

Using the operating key while the gauge is switched on and not placed

on a surface will display the possible measuring modes and "Unit".

The current measuring mode is then marked on the display. When the

operating key is used, the gauge switches to the next measuring mode

which activates if the button is not used again for 2 seconds. If "Unit"

is marked and nothing else happens, a menu opens with the entries 'µm'

and 'mil' and the current unit marked. Using the operating key you can

choose the unit you want.

Measuring with the Dual-Probe (QNix® 4500)

The gauge offers several ways to select the measuring mode. One way to

do this while the gauge is switched on is the operating key as described

above.

Fe- or NFe-mode:

For applications with clearly indicated substrate, the Fe or NFe mode can

be set as a fix mode. The current measuring mode is then indicated at the

left hand side.

Fe/NFe mode:

When constantly changing between steel and non-iron substrate, activate

the Fe/NFe mode. In this mode, indicated as two round arrows on the

display, the gauge switches to semi-automatic operation. A change of

substrate is then indicated by a message prompting to take another

reading by lifting and re-placing the probe.

Please note that the NFe measuring method allows measurements on

ferro-magnetic substrate (e.g. iron, steel). However, due to the substrate's

magnetic characteristics, the gauge does not display a correct result.

Therefore check whether the substrate is ferro-magnetic when using the

NFe measuring principle, e.g. by means of an additional check

measurement using the Fe measuring principle.

When using the NFe measuring principle, measurements on the supplied

zeroing plate might result in an INFI message or a number indicated on the

display. This can not be changed and is not a quality defect.

If you find the measuring results to be inadequate despite zero-adjustment

(e.g. if no zero results are produced when zeroing on the plates supplied),

deactivate the automatic mode selection and zero the gauge in both

modes using the plates supplied.
