1.0 INTRODUCTION

Checkline’s 3000PS Series gauges provide precise, non-destructive digital coating
thickness measurement on steel and non-ferrous metals.

Three models are available:

DCF-3000PS: For testing non-magnetic coatings such as varnish, paint, enamel,

chrome, copper, zinc, etc., on steel and iron.

DCN-3000PS: For testing varnish, paint and anodizing on non-ferrous metals and

on austenitic stainless steels.

DCFN-3000PS: Combines the ferrous and non-ferrous testing capabilities of the

DCF-3000PS and DCN-3000PS.

3000PS Series gauges employ the same familiar menu technique that is used in
cellular telephones.

There are 4 main menu sections:

- Calibrations,

- Statistics,

- Limit Values and

- Options.

All gauge functions are accessed from one of these main sections. The steps
necessary to reach and activate a particular gauge function appear on the display in
clear, easily understood language - place probe on Cal foil, for example. A
confirming message appears on the display as each step is completed.

Chapter 13 provides a diagram of the menu structure.

It will be helpful to take a few minutes to study this chapter while practicing using the
UP, DOWN, OK and ESC keys to move through the menus selections. The 3000PS
Series gauges are very easy to use. A few minutes spent familiarizing yourself with
using the keys to move through the menus is all the training required.

7.0 DATA TRANSFER

For data transfer from a 3000PS series gauge to a PC you must not use a possible
enclosed drive disc. For the infrared data transmission from the gauge to a printer or
to a PC, the following three requirements must be met:

1. The infrared adapter (accessory part) must be connected to the printer or PC.
The infrared window of the gauge and of the adapter must be parallel and face
each other at a distance of approximately 30cm to 50cm (12” to 20”) for the data
transmission.

2. The serial interface parameters of the PC and the printer must be set as follows:

Baud rate: 9600
Data bits: 8
Stop bit: 1
Parity: none
Handshake: none

3. A data transmission program must be installed for the data transmission to a
PC.

General information regarding the infrared data transfer using 3000PS

It is of special importance with reference to the infrared data transfer that the
transmitted light-induced pulses can be perfectly received and evaluated. The
infrared adapter receiving the light-induced pulses must therefore be protected from
any external interferences. For this reason, please observe the following:

• Do not expose the window of the infrared adapter to direct solar radiation.

• Do not operate any filament and halogen lamps in the immediate vicinity of the
adapter. The distance between adapter and lamp should be more than 1 meter.

• The infrared windows of the test instrument and of the adapter must be parallel
and facing each other at a distance of around 30 cm to 50 cm.

After pressing OK to start infrared data transmission, keep the gauge´s infrared
window pointed at the IR adapter as long as the green LED is lit.

4.4 Zero Offset

In this menu item, a constant positive or negative value can be set. This value is
automatically added to the measured value or subtracted from the measured value
every time a measurement is carried out. The display then shows the addition or the
difference. Moreover, the zero offset setting is always indicated below in the display
as a reminder.

This measuring mode is useful when determining the upper coating layer of a multi­layer system. If the lower layer(s) is (are) known and show an adequately uniform
thickness, the coating thickness of this (these) layer(s) can be set as a negative
offset value. The display then only shows the thickness of the top layer.

When measuring coated rough metal surfaces, this mode can also be selected. In
this case, the roughness effect, which is determined on the basis of the uncoated
rough metal surface, is set as a negative offset value. The instrument will then
