Frequently Asked Questions

Which Software version should I use for my gauge?

You must have a gauge with memory capability ( QNix 1500M, QNIx 7500M, QNix 8500 B, QNix 8500P). To simplify things, both versions of the software have been included on one CD. To download the CD, make sure the USB interface acble or the wireless USB Dongle is inserted into your USB port. The software will direct you through the download. Choose Version 6.2 for QNix 1500M and QNix 7500M. Choose version 7.2 for QNix 8500.

 

How do I verify proper installation of the Software Driver?

To verify proper installation of the driver, open the Device Manager (Control panel >System>Hardware>Device Manager). The newly downloaded device appears in the group "Ports". Note that Software version 6.2 can only handle COM Ports 1-4. So if your device is not working, and it is set at say COM Port 5, you will need to change to a lower COM Port. Make sure the chosen Com port is not occupied by another device. If it still does not work, "double click on "QNix USB Com port" in the device manager to get to the properties page. Now choose the Tab called "Port Settings" and then click on "Advanced". You will see all put that are available and which of them is already in use. Choose the port that is not occupied and then press "OK".

 

How do I change the Unit of my QNix 7500?

In order to change units you should have a Software and USB interface cable. Haven installed the software, insert USB cable to the USB port of your computer and the other end to the bottom of the gauge – slight the battery cover to access it. Then open the software and click of QuaNix. Go to change unit and click of the desired one and then again click get unit. If problems occur, your cable is probably not inserted properly.

 

What is the operating and storage temperature for QNix Coating Thickness Gauge?

Storage temperature  -10ºC - 60ºC  (14ºF-140ºF)
Operating temperature  0ºC - 50ºC ( 32ºF-122ºF)

 

What standards and regulations does QNix brand comply to?

Qnix brand complies to DIN 50981, 50984,: ISO 2178, 2360, 2808: BS 5411, 3900-C5: ASTM B499, D 7091.

 

When and how do I do a Zero-adjustment?

A new zero adjustment is required when using the gauge for the first time, working with different substrates or after inserting new batteries. To zero, place the probe of the QNix on one of the zero reference plates in the carrying case. For ferrous mode, place on ferrous plates and for non ferrous on non ferrous plate. It is better to use your own uncoated substrate to zero. Place the probe and press the red buton or switch. Release and lift the gauge about 4 inch away from the zero reference. Two numbers will appear and the gauge will read zero.

 

Why I am having problems zeroing the new version of the QNix 4200/4500?

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 of the zero plate or on your uncoated substrate. If the value indicated is not within the range of the basic tolerance, 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.

My QNix 8500 is showing dubious readings – what could be the reason?

Please check for the following:

  1. 1. Does your display show the correct substrate?
  2. 2. Are you zeroing on a dual mode – see dual signal on display.
  3. 3. If problem persists, reset gauge by removing batteries. Then set mode of gauge to single mode before zeroing.

 

I need to update the QNix 8500 gauge version Firmware?

Please go to www.automation.de and download the newest version.

 

What does this Display message mean?

Fe= measurement on iron or steel substrate

NFe= measurement on non-iron metal

Zero Reference Error = zeroing error or handling error

INFI= wrong substrate, reading beyond measuring range

low battery, have new ones ready= low battery, have new ones ready

low or empty battery= low or empty battery

automatic substrate selection activated= automatic substrate selection activated
