FAQ about our QNix® coating thickness gauges

General questions about QNix® coating thickness gauges

We generally recommend recalibration once a year – this is sufficient for many users. However, what users themselves define as their own quality features varies.

Yes. We want to ensure that the measuring device can be used quickly and therefore rely on replaceable parts. Contact us and we will send you a replacement part. We set ourselves the target that a measuring device sent to us should leave our premises after two days.

QNix® 9500 FAQ's - Handheld device

The QNix® 9500 is available in Basic, Premium and Premium+ versions, each as an integrated and modular probe version.

In the integrated version, the probe is permanently installed in the hand-held device and cannot be removed. It is therefore not possible to change the probe or connect a probe adapter cable.

The modular version allows the probe to be removed from the hand-held device. This makes it possible to change the probe or connect the probe adapter cable. The probe program of the modular hand-held device is larger.

Tips: You can recognize the integrated version by the black probe housing and the modular version by the grey probe holder.

No, a measuring probe is an optional extra for the modular version. The modular QNix® 9500 is supplied without a measuring probe. However, a measuring probe is usually ordered at the same time. Tip: No measurement can be carried out without a measuring probe.

The QNix® 9500 Premium+ is characterized by its increased storage capacity and the ability to create up to 100 jobs with 100 areas each. The QNix® 9500 Premium only allows 1 job with up to 100 areas.

If you want to document extensive measurement tasks, the QNix® 9500 Premium+ offers a major advantage in that you can create up to 100 measurement tasks (jobs), each with 100 subcategories (areas). You can take up to 10,000 measurements in each subcategory (area). This opens up countless possibilities for documenting measurements in the hand-held device and evaluating them later on the PC.

The Premium+ also offers the following preconfigured adjustment and limit value settings:

Adjustment settings Limit value settings
ISO 19840 Zero Offset ISO 19840
ISO 19840 2-Point SSPC PA2 (80/120) (Level 1-5)
SSPC PA2 Zero Offset IMO PSPC (90/10)
SSPC PA2 2-Point

Tips:

You can preconfigure and individually name the individual jobs and areas using the PC software. You then transfer these pre-configurations from the PC software to the handset.

You can start the next area by clicking on the freely assignable Q button on the handset.

The first question you should ask yourself is whether or not you want to document and analyze your measured values. If your answer to this question is yes, the QNix® 9500 Premium or Premium+ is the right choice.

If you want to save your measured values in different folders (jobs) on the device, we recommend the QNix® 9500 Premium+.

QNix® 9500 FAQ's - Operation

The focus frame enables quick navigation through the most important information in the measurement process.

In the lower position, you can switch between the graphical and the number-based display of statistical data.

In the middle position (measured value area), you can scroll through each measured value of the temporarily saved current measurement series or the activated area. Individual, e.g. incorrect measured values can be deleted directly.

In the upper position, you can change the individual areas of a job, depending on the device version. The respective statistical data is displayed in the lower area and the respective measured values in the middle area to match the corresponding area.

You navigate intuitively through the handset. The menu shows 4 tabs with submenu items. The video shows how easy it is to navigate the menu.

Tip: The handset remembers your position in the submenu of the respective tab when you switch between several tabs. These shortcuts allow settings to be made more quickly.

  1. Open the menu on the handset
  2. Switch to the red tab for limit values and averaging
  3. Select the type of limit value:
    • “No limits” (limit values and averaging are deactivated)
    • “Simple limit values” (maximum, minimum, averaging, automatic range)
    • “Individual” (Like simple limit value + maximum and minimum per spot)
    • Limit values according to standard ISO 19840, IMO PSPC or SSPC PA2 Level 1-5 (Premium+)
  4. Activate Minimum, for example, and set the value for the minimum permissible layer thickness

1. open the menu on the handset

2. select “New job

3. select “New empty job” to create a new job

QNix® 9500 FAQ's - Functions

If you have set limit values, the integrated LED limit value display immediately shows any deviation: red LEDs light up on the probe. Green illuminated LEDs indicate a measurement within the limit values.

You therefore have full control over whether a measurement is within your limit values without having to look at the device.

It is best to clean the probe and device with a damp cloth. The QNix® 9500 and the standard probes are chemically resistant to acetone (except for soft rubber parts such as the keypad and surrounding bumper), nitro thinner and ethanol.

The measurement technology is built into the fully digital probe. The accuracy of a measurement result is therefore independent of the respective hand-held device. QNix® has been using fully digital probes for 3 generations of probes. With the QNix® 9500, we have also succeeded in developing a particularly small digital probe.

Tip: All standard probes of the modular version can also be used in the QNix® 5500 hand-held device.

QNix® 9500 FAQ's - Software

Connect the QNix® 9500 to your PC using the USB cable supplied. The device is recognized as a mass storage device like a USB stick. An additional drive with the name “QNix® 9500″ is added in the file manager (file explorer). Open the drive and copy the file “QN9500_Software” to your PC. Execute the file. There is no installation, the file is simply unpacked. Execute the file “setFirewallRole4QN9” to register the software with your virus scanner. Press “Start_QNix9500” to start the application.

First you need to start the QN9 software on your PC, connect your handset and synchronize it with the software using the “File Sync” button. Then click on the “Creation” tab in the quick menu and the following screen will open:

  1. Select the appropriate job
  2. Select a report template
  3. Click on create & save

The creation of a report template works via drag-and-drop and is therefore almost self-explanatory
