Measuring Mode; Selecting The Substrate; Single Measurement / Continuous Measurement; Upper Limit - Automation Dr. Nix QNix 8500 Instruction Manual

A combined measurement can be useful when working on a ferromagnetic substrate that has
been coated in a metallic but non-ferromagnetic coating (i.e. zinc, chrome, etc.) and addi-
tionally in a synthetic coat of lacquer.
IMPORTANT: The metallic non-ferromagnetic coating must have minimum thickness of
50 µm (2mils).
8.2.2

Single Measurement / Continuous Measurement

In addition to the single measuring mode (standard), a continuous measuring mode can be
selected. In the continuous mode, the probe repeatedly takes readings in short intervals as
long as it is placed on the surface.
The continuous mode is indicated with the symbol.

Upper Limit

8.2.3.1 Setting the Upper Limit
When no limit has been set, press the ► button to see the last reading.
When a limit has been set, pressing the ► button will show the current limit..
Use the ▲ and ▼ Buttons to set the upper limit and confirm by pressing ►.
Readings exceeding the upper limit are indicated with the symbol ^ in the display and with an
audio warning signal.
8.2.3.2 Deleting the Upper Limit
To delete the upper limit press the ► button and confirm "OK" by pressing ► again.
8.2.4

Lower Limit

To set or delete the lower limit please follow the instructions given under § 8.2.3.
Readings below the lower limit are indicated in the display with the ˇ symbol and with an au-
dio warning signal.
8.2.5

Averaging

When working on substrates with large variations in coating thickness, or to meet the re-
quirements of a test standard, the gauge can be set to calculate and then display the valid
coating thickness value from a predefined number of measurements.
To activate the averaging set the number of readings by using the ▲ and ▼ buttons in the
next menu level; then confirm with ►.
The symbol x indicates this mode in the display.
While taking measurements in this mode, the individual values are displayed in a small font
size together with a counter for the remaining measurements. When all individual values
have been recorded, the average is displayed in standard font size.
8.3

Data Memory

With this menu option, you activate/deactivate the memory function and manage/configure
the batches.
After pressing the ► button, the marker will always jump to the active item in the next menu
level: with the data memory mode deactivated the marker jumps to "OFF"; with activated da-
ta memory mode, the currently active batch is highlighted.
8.3.1 Delete All
Confirming this menu item by pressing the ► button deletes the entire memory content after
a confirmation dialog.
