1. Instrument Overview

This chapter provides a brief overview of the Olympus NORTEC 600 eddy current flaw detector, and includes the principle of operation, accessories, and all common operational requirements.

1.1 Operating Principle

The NORTEC 600 is a small, lightweight flaw detector designed to make fast, accurate, and repeatable measurements on conductive materials such as aluminum, copper, stainless steel, steel, and titanium.

The NORTEC 600 uses electromagnetic induction to detect flaws in conductive materials. Electromagnetic induction is achieved with a coil that carries a current and that is placed in proximity to the test material. The alternating current in the coil generates a changing magnetic field that interacts with the test material and causes eddy currents. Variations in the phase and magnitude of these eddy currents are monitored. Variations in the electrical conductivity or magnetic permeability of the test object, or the presence of any flaws, will cause a change in eddy current and a corresponding change in the phase and amplitude of the measured current.

Eddy current testing can detect very small cracks in or near the surface of non-ferrous material, and it is also useful for making electrical conductivity and coating thickness measurements. The surfaces being tested need minimal preparation.

The NORTEC 600 includes a clear plastic sheet protecting the instrument display window. Olympus strongly recommends leaving this protection sheet in place. Replacements are available in packages of ten sheets (Olympus P/N: 600-DP [U8780297]).

The display window is permanently bonded to the instrument case to fully seal the instrument. If the display window becomes damaged, the front part of the case must be replaced, along with the instrument’s keypad.

1.6.4 Environmental Ratings

The NORTEC 600 is an extremely rugged and durable instrument that can be used in harsh environments. To classify the instrument’s durability in wet or damp environments, Olympus has adopted the IP (ingress protection) system to rate how well the instrument is sealed.

The NORTEC 600 is designed and manufactured to meet the requirements of the IP66 ingress protection rating. To maintain this level of protection, you are responsible for the proper care of all routinely exposed membrane seals. Additionally, you are responsible for returning the instrument to an authorized Olympus service center each year to ensure that the instrument seals are properly maintained. Olympus

Chapter 146

Chapter 470

Figure 4‑2 The NORTEC 600 instrument controls

Page 81

DMTA-10040-01EN, Rev. E, February 2018

NOTE

4.2.1 Display

The NORTEC 600 instrument is configured with a color liquid crystal display (LCD) and offers 640 × 480 resolution (full VGA). The LCD display, also referred to as a screen, shows the eddy current signal, menus, status bar, messages, and full screen text when required. Several display modes are available (see “Display Menu — DISP Key” on page 87).

4.2.2 Power and Lock Buttons

The power button ( ) toggles the instrument power on and off. At startup, the instrument will normally attempt to restore its last configuration.

The instrument lock can be enabled or disabled by pressing the lock button ( ). When activated, the lock disables most of the instrument function keys, menu keys, and the knob. This prevents inadvertent key entries after the instrument is calibrated and ready to proceed with inspections.

When the lock is activated, an indicator light ( ) illuminates below the battery life indicator at the upper right side of the instrument screen, and only the NULL, ERASE

( ), and ANGLE ( ) direct-function keys remain functional.

When the instrument lock is enabled, the knob is available after the ANGLE direct-

function key ( ) is pressed.

4.2.3 Direct-Function Keys

The direct-function keys located on the left side of the instrument are used to directly select the instrument settings that are most often used for adjustment. Three of the

direct-function keys—A-LIFT NULL ( ), FREEZE ( ), and REF SAVE ( )—have more than one main function.

Control Functions 71

Page 82

DMTA-10040-01EN, Rev. E, February 2018

NOTE

A-LIFT NULL ( )

The primary function of the A-LIFT NULL key ( ) is to “null”, or initialize to zero, the instrument screen. The secondary function of this key is to enable the A‑ LIFT (Auto Liftoff) function, which automatically sets the probe liftoff from left to right (horizontally).

To enable A-LIFT (Auto Liftoff)

The steps that follow assume that the following criteria have been met:

• A probe is connected to the NORTEC 600 instrument.

• The probe has been “nulled” normally.

• The liftoff is not horizontal (see Figure 4-3 on page 73).

• The probe is in contact with the reference standard.

1. Press and hold the A-LIFT NULL direct-function key ( ) until a “beep” sound signal is heard (approximately 3 seconds) and the text “LIFT PROBE” is displayed on the instrument screen (see Figure 4-4 on page 73).

2. After the sound signal and LIFT PROBE message, lift the probe off the reference standard.

The instrument calculates the change required to correct the instrument ANGLE setting.

3. Null the probe again.

The probe liftoff should resemble the image shown in Figure 4-5 on page 74.

The accuracy of Auto Liftoff depends on factors such the angle at which the probe was lifted off the reference standard, and the material condition. Results may vary,

and minor adjustments using the ANGLE direct-function key ( ) may still be necessary.

ERASE ( )

Provides the ability to erase the instrument screen instantly; this key does not have a secondary function.

FREEZE ( )

The primary function of the FREEZE key ( ) is to freeze the current image on

the instrument screen for further evaluation. When the FREEZE key ( ) is pressed, the data acquisition stops and an indicator (capital letter “F”) is displayed on the instrument screen below the battery charge indicator (see Figure 4-6 on page 75). When FREEZE is active, the functionality of the A-LIFT

NULL key ( ) and ERASE key ( ) is disabled, and a “beep” sound signal is emitted if either of these keys is pressed.

Chapter 474

Page 85

DMTA-10040-01EN, Rev. E, February 2018

Figure 4‑6 Freezing the current image on the instrument screen

The secondary function of the FREEZE key ( ) is to allow adjustment or manipulation of the frozen screen image. This is useful when calibrating for the inspection being performed. The direct-function keys that are functional while

FREEZE is enabled are GAIN ( ), ANGLE ( ), and FREEZE ( ):

— Pressing the GAIN key ( ) after FREEZE is enabled will alter the screen

image to estimate the effect of a reduction or addition of gain on the instrument after FREEZE is disabled. Gain may be altered vertically, horizontally, or combined vertically and horizontally (see “GAIN” on page 76 for more details on changing the gain).

— Pressing the ANGLE key ( ) after FREEZE is enabled will alter the

screen image to estimate the effect of changing the angle setting on the instrument signal after FREEZE is disabled. (see “ANGLE” on page 76 for more details on changing the angle).

— Pressing the REF SAVE key ( ) after FREEZE is enabled will save the screen

image and instrument settings to memory (see “REF SAVE” on page 76 for more details on REF SAVE). While FREEZE is active, the SET REF (set

reference) functionality is disabled. If the REF SAVE key ( ) is pressed and held for approximately 3 seconds, the instrument sounds a “beep,” which indicates that the image and settings are successfully saved.

To exit the FREEZE mode, press the FREEZE key ( ).

Multiple presses of the GAIN key ( ) will toggle between the combined horizontal and vertical gain settings, the horizontal gain settings only, or the vertical gain settings only. The knob is the primary method of changing this setting. For more information on gain, see “GAIN” on page 83.

ANGLE ( )

Used to adjust the instrument’s angle settings. Pressing this key provides direct access to the instrument’s angle settings while any instrument settings are displayed in the instrument’s settings menu (see Figure 2-5 on page 53). Pressing

the ANGLE key ( ) will display the instrument’s angle settings in the quickaccess bar shown in Figure 2-5 on page 53. The knob is the primary method of changing this setting. For more information on angle, see “ANGLE (rotation)” on page 82.

REF SAVE ( )

The primary function of the REF SAVE direct-function key ( ) is to save instrument’s settings and screen images to the instrument memory. When the REF

SAVE key ( ) is pressed once (and released), the currently displayed image and settings are saved. Saved settings can later be recalled for reoccurring inspections. Saved screen images can be used in reports. Saved images can also be displayed on-screen to aid inspections (for more details, see “MEM” on page 77).

The secondary function of the REF SAVE direct-function key ( ) is to set the

current image as the reference image. If the REF SAVE key ( ) is pressed and held (for approximately 3 seconds), the current instrument image is set as the reference memory display, as outlined in “SET REF (set reference image)” on page 94. After the image has been successfully saved in the reference memory, the instrument will sound a “beep.”

4.3 Menus

The NORTEC 600 menus described in this section are opened by pressing the corresponding menu keys, which are described in “Menu Keys” on page 77.

4.3.1 Frequency (FREQ 1) Menu — MAIN FILTER Key

FREQ (frequency)

The FREQ setting determines the frequency of the drive signal of the eddy current probe. This is adjustable from 10 Hz (0.01 kHz) to 12 MHz.

To adjust the frequency setting, press the MAIN FILTER menu key ( ), followed by the A key. With FREQ highlighted, rotate the knob until the desired frequency is displayed.

To speed up the frequency selection process, press the Enter key ( ) once while the FREQ function is highlighted to enable the coarse knob function. FREQ will be underlined when this function is enabled. To turn off the coarse-knob function, press

one more time.

ANGLE (rotation)

The phase angle (or rotation) of the eddy current signal is set using the ANGLE

key ( ). By default, the angle is set in 1 degree increments, from 0 to 359 degrees.

To adjust the angle setting, press the MAIN FILTER menu key ( ), followed by the B key. With ANGLE highlighted, rotate the knob until the desired angle is displayed.

Page 93

DMTA-10040-01EN, Rev. E, February 2018

TIP

To enable the fine-knob function, press the Enter key ( ) when ANGLE is highlighted. The fine-knob function can be used to adjust the angle more precisely. ANGLE will be underlined when this function is enabled. The angle can then be

changed in 0.1 degree increments. To turn off the fine-knob function, press one more time.

GAIN

Gain is adjustable from 0.0 dB to 100.0 dB. The displayed gain setting is adjusted in 0.1 dB steps. At full gain (100 dB), with the instrument’s probe drive set to MEDIUM, instrument sensitivity is 10 V/Ω, as measured at the rear panel horizontal and vertical outputs. In other words, ten screen divisions represents an impedance change of one ohm on the display.

Gain can be adjusted independently in the horizontal or vertical direction, or in both directions simultaneously. The primary method of adjusting gain is by turning the knob. However, gain may also be adjusted by using the knobless function (for more details, see “Knobless Entry” on page 78).

To adjust the horizontal and vertical gain simultaneously, press the MAIN FILTER

menu key ( ), followed by the C key. The gain may then be adjusted with the knob. The selected value will be applied to both the horizontal and the vertical gain, and the difference between the horizontal and vertical gains will remain constant; they will increase or decrease at the same rate.

To adjust the horizontal gain only (without changing the vertical gain), press the

MAIN FILTER menu key ( ), followed by the D key. The knob will then adjust only the horizontal gain. To adjust only the vertical gain, press the E key. The knob will then adjust only the vertical gain.

To speed up the gain selection process (while the combined horizontal and vertical

gain, horizontal gain, or vertical gain function is highlighted), press once. This enables the coarse-knob function. GAIN, H GAIN, or V GAIN will be underlined

when this function is enabled. The gain can then be changed in 1.0 dB increments. To

turn off the coarse-knob function, press one more time, which returns the gain adjustments to 0.1 dB increments.

4.3.2 Filter Menu — MAIN FILTER Key

Filters

High-pass filters may be set from 0 Hz (OFF) to 100 Hz in 1 Hz increments, and from 100 Hz to 1000 Hz in 5 Hz increments. To adjust the HI PASS filter settings,

press the MAIN FILTER menu key ( ) two times, followed by the A key, and then rotate the knob to the desired value.

Low-pass filters may be set from 10 Hz to 100 Hz in 1 Hz increments, up to 500 Hz in 5 Hz increments, and up to 2000 Hz in 25 Hz increments, followed by wide band. To adjust the LO PASS filter settings, press the MAIN FILTER menu

key ( ) two times, followed by the B key, and then rotate the knob to the desired value.

CONT NUL (continuous null)

CONT NUL allows a very low-frequency high-pass filter to be turned on, which

is useful to keep the null point of the eddy current probe at the specified point, if required. When turned on, this function adds a 0.2 Hz, 0.5 Hz, or 1 Hz high-pass filter. By default, this feature is set to OFF.

To turn on continuous null, press the MAIN FILTER menu key ( ) two times, followed by the C key, and then rotate the knob to the desired value.

To adjust the SCAN RPM setting, press the MAIN FILTER menu key ( ) two times, followed by the E key, and then rotate the knob to the desired value.

4.3.3 Special Menu — MAIN FILTER Key

PRB DRV (probe drive)

The NORTEC 600 instrument has three levels of probe drive that can be selected: LOW, MEDIUM, and HIGH. The approximate peak-to-peak voltages are 2 V, 6 V, and 12 V, respectively.

MEDIUM probe drive (the default setting) is normally sufficient for most eddy current testing. However, HIGH probe drive is desirable in the following cases:

a) If gain is insufficient at the lower probe-drive settings.

b) During testing of lower conductivity materials.

c) For finding smaller flaws in the test material.

d) For deeper penetration into the test material.

DMTA-10040-01EN, Rev. E, February 2018

To adjust the probe-drive level, press the MAIN FILTER menu key ( ) three times, followed by the A key. With PRB DRV highlighted, rotate the knob to the desired level.

PRB CONN (probe connection)

The NORTEC 600 instrument supports two types of probe connections: BNC and 16-pin LEMO. The probe input by default is set to 16-pin LEMO. If the BNC connector is used, the connection input needs to be changed manually.

To adjust the probe-connection input, press the MAIN FILTER menu key ( ) three times, followed by the B key. With PRB CONN highlighted, rotate the knob to select the desired connector: LEMO‑16 or BNC.

NOTE

predetermined amount of time. This time may be set from 0.1 s to 10 s, in 0.1 s increments. By default this feature is set to OFF.

PERSIST erases all information at a particular point after the selected amount of time has expired, even if more information is displayed there at a later time. As a result, the displayed signal might appear broken where the eddy current signals intersect the signals being erased. However, the resulting display is very useful for repetitive testing, because it is no longer necessary to manually erase the screen.

To activate variable persistence, press the DISP menu key ( ), followed by the Ckey. With PERSIST highlighted, rotate the knob to adjust to the desired value.

PERSIST is not available if display erase (D ERASE) or sweep mode (SWEEP) is activated. In some applications, PERSIST may slow down the instrument’s data acquisition rate, resulting in decreased instrument performance. If this is the case, it is recommended to use display erase instead.
