IWK-CG304Wireless Coating Thickness Tester

USER GUIDE Coating Thickness Tester With Bluetooth® Model CG304 CG304-EU-EN v1.0 6/14 2 Introduction Congratulations on your purchase of the Extech CG304 Coating Thickness Tester. The CG304 is a portable meter designed for non‐invasive coating thickness measurements with automatic recognition of the material under test. The meter uses two measurement methods: magnetic induction (for ferrous metal substrates) and eddy current (for non‐ferrous metal substrates). The Bluetooth® feature wirelessly transmits measurement data to a PC for further analysis and to generate report documentation. Proper use and care of this meter will provide many years of reliable service . Description Meter Description 1. LCD display 2. Power key 3. Probe 4.

The display will switch ON. If the display does not switch ON, install or replace the batteries. Measurements Use the film references and zero reference metal substrates to learn how the meter operates before moving to a professional application. The round metal substrate is the ferrous (magnetic) substrate and the rectangular shaped metal substrate is the non‐ferrous (non‐magnetic) substrate. The meter automatically senses ferrous and non‐ferrous substrates. 1. Place a reference film (250μm, for example) on the round, ferrous substrate. 2. Place the spring‐loaded meter sensor against the reference film. 3. In the single mode the meter will emit an audible tone indicating that the measurement has been taken. 4. In the continuous mode the display will continually measure and update the display 5. The LCD will show the reading (250μm) at the center of the display area. 6. A typical display will also show the following:  NO = 1 (reading number one) on the lower left of the LCD  AVG = 250μm (running average) on the lower right  DIR = DIR mode of operation on the upper left  Fe = Ferrous substrate on the upper right of the LCD Experiment with the remaining reference films and the substrate before using the meter professionally. Automatic Power OFF In order to conserve battery life, the meter will automatically turn off after approximately 10 minutes. To defeat this feature use the programming menu detailed in the next section (menu parameter AUTO POWER OFF under OPTIONS). DIR um AVG=250NO=1 250 Fe CG304-EU-EN v1.0 6/14 4 Programming Menu The meter can be configured and calibrated through simple button presses in the programming menu. Press the LEFT button to access the menu and refer to the menu ‘tree’ below. The menu uses UP/DOWN, LEFT/RIGHT presses for navigation and selection. In the table below the factory default settings are in bold with an asterisk. Each parameter is explained in detail in the subsequent sections.

CG304-EU-EN v1.0 6/14 5 STATISTICAL VIEWS Menu 1. Press the LEFT button to access the programming menu 2. Press the LEFT button to choose STATISTCAL VIEW 3. Use the UP and DOWN buttons to scroll through the AVERAGE, MINIMUM, MAXIMUM, NUMBER OF DATA, and SDEV (Standard Deviation) values for the stored readings. 4. ‘NO DATA’ will display if no readings are available for the meter to analyze. Stored readings will clear when the meter powers down unless the GROUP feature is used (refer to GROUP function explanation later in this section). 5. Press the BACK and then the ESC soft‐keys to return to the normal operating mode. OPTIONS Menu 1. Press the LEFT button to access the programming menu 2. Use the UP/DOWN button to scroll down to OPTIONS 3. Press LEFT button to select OPTIONS 4. Use the UP and DOWN buttons to scroll to the MEASURE MODE, WORKING MODE, PROBE USED, UNIT SETTINGS, BACKLIGHT, LCD STATISTICS, AND AUTO POWER OFF parameters. Use the LEFT soft‐key to select the desired par…

FCC ID IWK-CG304 Frequency Hopping system filing requirements Requirements EUT Condition Comply Pseudorandom Frequency Hopping Sequence Describe how the hopping sequence is generated. Provide an example of the hopping sequence channels, in order to demonstrate that the sequence meets the requirement specified in the definition of a frequency hopping spread spectrum system, found in Section 2.1. The channel is represented by a pseudo-random hopping sequence hopping through the 79 RF channels. The hopping sequence is unique for the piconet and is determined by the Bluetooth device address of the master; the phase in the hopping sequence is determined by the Bluetooth clock of the master. The channel is divided into time slots where each slot corresponds to an RF hop frequency. Consecutive hops correspond to different RF hop frequencies. The nominal hop rate is 1 600 hops/s. Example of a 79 hopping sequence in data mode: 40, 21, 45, 23, 42, 53, 46, 55, 48, 31, 51, 35, 50, 65, 54, 67, 56, 37, 60, 39, 58, 69, 62, 77, 64, 25, 68, 27, 66, 57, 70, 59, 72, 29, 76, 33, 74, 61, 78, 63, 01, 41, 05, 43, 03, 73, 07, 75, 09, 44, 15, 47, 11, 71, 13, 00, 64, 49, 66, 53, 68, 02, 70, 06, 01, 52, 03, 55, 05, 04 Y Equal Hopping Frequency Use Describe how each individual EUT meets the requirement that each of its hopping channels is used equally on average (e.g., that each new transmission event begins on the next channel in the hopping sequence after the final channel used in the previous All Bluetooth units participating in the piconet are time and hop-synchronized to the channel. Y Page 2 of 2 transmission event). System Receiver Input Bandwidth Describe how the associated receiver(s) complies with the requirement that its input bandwidth (either RF or IF) matches the bandwidth of the transmitted signal. Each channel bandwidth is 1 MHz Y Equipment Description 15.247(a)(1) that the rx input bandwidths shift frequencies in synchronization with the transmitted 15.247(g): In accordance with the Bluetooth Industry Standard, the system is designed to comply with all of the regulations in Section 15.247 when the transmitter is presented with a continuous data (or information) system. 15.247(h): In accordance with the Bluetooth Industry Standard, the system does not coordinate it channels selection/ hopping sequence with other frequency hopping systems for the express purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters.
