2.0 Product Description

The MIZ-28 instrument is used for eddy current inspections of heat exchanger tubing in balance-of-plant applica-

tions. It works seamlessly with all existing Zetec software and hardware products.

Zetecs MIZ-28 offers a color display, selectable data presentation, menu-driven user interface, high digital sampling

rates, bandpass and differential filters, and two independent balance controls. This versatile, fully digital tester

provides maximum stability, reliability, and sensitivity.Testing capabilities include heat exchanger and air condi-

tioner tube testing, weld inspection, and a broad variety of other eddy current applications. Packaged in a rugged

portable carrying case, the MIZ-28 is ideal for industrial environments.

An active matrix color display shows test information from almost every angle. The use of color provides quick chan-

nel identification without having to read the setup screen. The real-time display constantly indicates the coil

impedance point shift and closely emulates a storage oscilloscope display.

The MIZ-28 presents the phase and amplitude vectors of the eddy current signal as a two-dimensional Lissajous fig-

ure. Simultaneous display of up to four Lissajous figures and two strip charts enables you to efficiently monitor mul-

tiple data channels.

The MIZ-28 internal hard drive adds 40 GB of data storage capacity to the MIZ-28 for data acquisition and tube list

storage.

Figure 2-1 MIZ-28 Front and Back Panels

It is recommended that you are familiar with Eddy Current theory and application before using the

MIZ-28, and that you use it only for the functions for which it has been designed.

Zetec offers a wide variety of courses dealing with electromagnetic inspection theory and applica-

tions. This includes classes that are specific to either eddy current testing (ECT) or remote field

testing (RFT). Some formal courses can be used to help qualify inspectors to meet specific certifi-

cation criteria for either data acquisition or data analysis. Other informal courses can be designed

with variable content and duration to meet specific application needs. Contact the Training Depart-

ment at 425-974-2700 for more details.

3.2 Initial Setup of the MIZ-28

Because the most common use of the MIZ-28 will be for examinations of heat exchanger tubing with a pair of bobbin

coils, that is the type of setup described here. This ECT technique provides a rapid volumetric inspection of the

tube wall, assuring 100% coverage. Many other probe designs can be accommodated if special inspection criterianeed to be met. Up to eight (8) coil pairs can be used.

1. Turn the instrument on.

2. Connect the bobbin probes to the Coil ports on the back plane. Specific probe adaptors will be required (see

system drawings in Appendix A). NOTE: It is possible to connect and/or disconnect the probe adaptors without

turning the power off.

4.2.1 Config Type

The MIZ-28 supports both multiplexed and simultaneous injection testing.

Mul t ip lexed

It is recommended you use the multiplexed mode for the following probes:

Bobbin (differential and absolute with external reference)

MRPC

Array probes (that do not require external multiplexing hardware)

AC3 probes

The MIZ-28 supports four test frequencies in multiplexed mode.

Simul t aneous Inject ion

In simultaneous injection mode, the number of available frequencies depends on the number of coils being used andthe number of boards present in the unit. With the two analog board MIZ-28, you can run a two coil test at four fre-

quencies, a four coil test at two frequencies, or an eight coil test at one frequency.

4.3 Adjusting the Sample Rate

You can adjust the sample rate from 1 up to a maximum of 16,000 samples per second. The maximum sample rate

allowed depends on the number of test frequencies in use and the value of the test frequencies.

To adjust the sample rate:

1. Press the SAMPLE RATE (F3) button to enable the function.

2. Use the Control Knob to select the samples per second.

3. In Simultaneous mode only, press the SELECT FILTER(F9) button to set the filter rate.

Figure 4-8 Sample Rate

4.3.1 Sample Rates in Multiplexed Mode

Four different filters 4K, 8K, 12K and 16K are available for use in the signal processing circuitry when operating

in multiplexed mode. The 4K filter produces the best signal-to-noise, though at the cost of sample rate. The 16K fil-

ter allows faster sampling rates at the cost of signal-to-noise. Switching from the 4K filter to the 8K filter, you can

expect to lose 3dB of signal-to-noise. Switching from 8K to 12K or 12K to 16K filter, you can expect to lose 1.5dB of

signal-to-noise. The instrument automatically selects the best possible filter for the configured parameters and dis-

plays it next to the maximum sample readout. As you increase or decrease the sample rate, the filter setting will

change.

4.3.2 Sample Rates in Simultaneous Mode

Four filters are available in simultaneous mode: 240Hz pass band, 400Hz pass band, 800Hz pass band and 1600Hz

pass band. The trade-off when using these filters is signal-to-noise versus pull speed. Given the general rule of 10Hz

of pass band per inch pulling speed, the 240Hz filter has about 24ips max pull speed and the 400Hz has about 40ips

max pull speed. As you start decreasing test frequencies, the max pull speed value displayed to the right of the

sample rate decreases. You should expect the 240Hz filter to have a 2.5dB gain in signal to noise.


42/169

Configuration

Setting Test Frequency Values

Page 4-9

4.4 Setting Test Frequency Values

The MIZ-28 supports up to four test frequencies from 5 Hz to 10 MHz. To eliminate cross talk between frequencies in

simultaneous mode, a minimum frequency separation rule must be followed. If there is not enough separation

between test frequencies, the frequencies in violation will turn red and the message, Not enough frequency sepa-ration will be displayed at the bottom of the screen.

A special filter design is implemented in the MIZ-28 to improve performance at low test frequencies. This is to

improve RTF testing performance and signal noise. This filter will automatically be selected if the configuration

allows for it. When the filter is applied, you will see an increase in the max pull speed (ips) value on the configura-

tion screen and an LF (low frequency filter) will appear. This filter is only applicable in the SI mode.

You can select up to four instrument test frequencies, depending on the test configuration.

To select a test frequency:

1. Press the FREQUENCY SELECT(F4) button.

2. Use the Control Knob to select the frequency you want to change.

3. Press the ADJUST (F9) button and use the Control Knob to adjust the frequency value.

Selecting a Channel

Page 4-11

4.6 Selecting a Channel

Each channel is described by a frequency and coil combination. You can turn a channel ON or OFF. Once a coil has

been activated, a balance number is associated with it. The balance assignment is by coil. There are two separate

balances available in the MIZ-28.

In multiplexed mode, you can turn on two coils per timeslot per board for a total of four channels per timeslot.

In simultaneous mode, the number of available coils depends on the number of test frequencies used. The two ana-

log board MIZ-28 is capable of running a two coil test at four frequencies, a four coil test at two frequencies, or an

eight coil test at one frequency.

To select a channel:

1. Press the CHANNEL SELECT (F6) button.

2. Press the COIL NUMBER(F8) button, and then use the Control Knob to select a coil number.

3. Press the FIELD (F9) button to set the field.

4. When the field is in one of the frequency lines, press the TOGGLE ON OFF (F10) button to toggle the channels

ON or OFF. In simultaneous mode all channels for that coil will be turned ON or OFF.

5. When the cursor is scrolled down to the balance number line, the F10 button label changes to BALANCE NUM-

BER. Press F10 and use the Control Knob to assign a balance number to the channels configured to that coil.

2. Scroll the tube end signal to the cursor and press the SET THRESHOLD button. This will take the peak measure-ment of the tube end and save it to NVRAM. A message at the bottom of the page will display saying, Thresh-

old has been set.

Tube End Detect ion

Press the TUBE END DETECTION (F2) button to enable or disable the function.

When tube end detection is enabled, every time the pusher starts running the data will be monitored for a signal

that is greater than 80% of the set threshold limit (tube end signal). When a signal of great enough amplitude is

detected, the instrument will turn off the pusher. The exception is when Standard Run is enabled. In this case, the

instrument will not monitor for the threshold signal.

Thr eshold Delay

Press the THRESHOLD DELAY (F10) button, and then use the Control Knob to change the delay time in milliseconds

(mS).

The Threshold Delay is the amount of time that the instrument will wait to begin processing data after a pusher

move has been initiated. This delay allows the probe to enter the tube without triggering a threshold event.

Auto Retr act

Press the AUTO RETRACT (F11) button to enable or disable the function. When auto retract is enabled and a thresh-

old event is encountered in the forward direction, recording will be started and the pusher will automatically start

running in the reverse direction. The next threshold event will stop the pusher and stop recording.

In addition, when auto retract is enabled, the pusher will start running in the reverse direction whenever the START

RECORDING button is pressed. Any time the pusher is running and the STOP RECORDING button is pressed, the

pusher will be stopped.

6.2.7 Filter Setup

Filter adjustments do not affect the analog probe signal. They are digital filters that optimize the presentation and

aid in signal analysis. This allows you to experimentally change the filters in review mode without the need to re-

acquire the data. There are two types of filters available with the MIZ-28: a first order differential filter and a low

pass filter. The differential filter is adjustable from 2 to 40 points; the low pass filter is adjustable from 0 Hz to

about half of the current sample rate. When a channel has a filter associated with it, you will see the words DIFF, LP,

or LP+DIFF on the end of the X-Y channel information.

Figure 6-19 Filter Setup Screen





Fi l te r Type

Press the FILTER TYPE (F9) button and rotate the Control Knob to change the filter type associated with the

selected channel. The options are off, low pass, differential, or a combination of low pass and differential. The

low pass filter is a 41 coefficient digital filter with sharp cutoff characteristics. Its useful in suppressing a variety ofunwanted signals including electrical interference. The first order differential filter displays the difference between

the present data point and a previous data point. The closer the data points are together in time, the more high-

pass action the filter creates. The process is sometimes known as continuous balance, because the displayed signal

has been compared to some recent value, rather than a fixed point. This filter is useful when the probe is scanned

across dissimilar materials, as it tends to keep the signal on screen. The differential filter is sensitive to the direc-

tion of data change. Rising edges will show as positive signals, and falling edges will show as negative signals. For

this reason, a single unfiltered pulse, which deflects upwards and then returns to null, will appear filtered as a pos-

itive and then a negative signal.
