1. Measuring Principles and Characteristics

• LH-330J

(Eddy Current measurement method: For measuring the thickness of insulating coatings on non-magnetic metal substrates)

An eddy current is produced in the surface of a metal when a coil through which a current of fixed frequency is brought near the metal. This eddy current and the voltage at the ends of the coil change in proportion to the distance between the coil and the metal surface. This change can be determined from the current value and this is used to calculate the thickness of the coating.

• LE-330J

(Electromagnetic measurement method : For measuring the thickness of non-magnetic coatings on magnetic metal substrates)

When an alternating current electromagnet is brought near iron (or other magnetic metal) the number of magnetic flux lines passing through the coil changes in proportion to the distance, thereby causing a change in the voltage at the ends of the coil. This change in voltage is determined from the current value and this is used to compute the thickness of the coating.

• LZ-330J(Dual Electromagnetic and Eddy Current Type)

The model LZ-330J is a dual type coating thickness tester which features both the electromagnetic and Eddy Current measurement methods.

6. Preparations for Operation

1. Insert the batteries

The battery cover is opened by sliding the battery cover on the rear of the case in the direction indicated by the arrowhead mark ( " ∆ " ). Insert 4 size AA alkaline batteries into the batter y compartment as indicated by the picture in the compartment. Take care to align the positive and negative ends of the batteries correctly.

2. Selecting and Connecting the probe (LZ-330J)

Select a probe appropriate to the type of sample to be measured with switching the main unit off.

4. Using the probe

The probe features a 1-point contact, fixed pressure design which ensures fixed load applied the chip on the tip the probe. As shown in the diagram, grip the probe near the tip and press it against the measurement surface so that it is perpendicular to the surface. To make the next measurement, lift the probe tip at least 10mm from the measurement surface and then press it down again.

•The probe adapter can be used to obtain stab le, reliab le measurements when measuring coatings on curved surfaces such as pipes , etc., or when making continuous measurements on a flat surface.

3. Adjustment preparation

Adjustments must be made attempting to make measurements. However, measurement calibrations are stored in the unit’s computer memory, therefore new adjustments are not required if the sample to be measured has been measured previously. In this case, the previous adjustments can be recalled from memory.

1A standard "substrate" of the same material,shape and

thickness as the sample to be measured is used to make calibration adjustments. Hav e the standard substrate ready before beginning the adjustment procedure.

•Use bare standard substrates which are free of coatings such as plating or paint. Standard substrates of this type are ref erred to as "z ero f oils" in this manual.

2In order to obtain the most accurate precise measurement

results possible, adjustments are perf ormed with zero foils and standard foils (samples of known thickness) using the Standard Foil 4-point Adjustment Method.

•Ref er to the chart to select a set of 3 standard foils appropriate for making adjustments for the thickness of the coating to be measured.

•The supplied standard f oil values will not necessarily be e xactly the same as those indicated in the chart. Instead, standard plates with actually measured values close to these values are supplied.

•An attached standard board is used for an easy accuracy check.

It attaches in the point of a probe with an adapter. Furthermore, a screw is tightened.

5. Calibration

Specify calibration memory address at which to store calibration settings.

The LZ-330J has the capacity to store up to a maximum of 4 calibration settings for both electromagnetic and eddy current measurement modes, and the LE-330J has the capacity to store up calibration settings for 4 electromagnetic mode and LH-330J also has the capacity to store up calibration setting for 4 eddy current mode. The calibrations used for a particular measurement are selected depending upon the type of sample being measured. The calibration memory address (APL#) at which a particular set of calibration settings is stored is selected at the beginning of the adjustment (calibration) procedure.

The memory addresses that can be used for electromagnetic and eddy current calibration settings are as follows:

(LE-330J • LZ-330J)

Electromagnetic Mode (Fe Probe) A1, A2, A3, A4

(LH-330J • LZ-330J)

Eddy Current Mode (NFe Probe) A5, A6, A7, A8

•After po wering on and after switching between electromagnetic and eddy current mode, the unit is automatically set to the previous APL#. If it is

not necessary to change this, press key.

9. Easy Calibration (For Eddy Current method only)

Simplified "easy" adjustment can be made in order to make Eddy Current measurement mode measurements. (Easy adjustment is not possible for the electromagnetic measurement mode.) If the coating thickness does not exceed 500µm, measurement results are as precise as those obtained using standard foil calibration adjustments. In the easy adjustment procedure, only the substance calibrations are perf ormed. Once substance calibrations have been registered it is not necessary to perform this procedure each time measurements are made. However, the substance calibration procedure must be redone in cases such as if the probe is replaced with a new one, etc.

•

This type of calibration adjustment is only valid for the eddy current measurement mode.

Press the ENT key 10 times.

Step

Operation Display Explanation

○○○○○○

○○○○○

Press the key.

Press the key 10 times while pressing the probe against the substrate.

•The substrate should be an uncoated (no plating, paint, etc.) sample of the same shape and material as that to be measured.

After pressing the key 10 times the buzzer will sound intermittently and "IF" will appear in the display.

Press the key while holding the probe toward the air.

•The probe must be in the air, don’t touch any surface or others.

10. Notes for Measuring and Handling

(1) Confirm the type of material being measured.

Be sure to check the type of material and select the correct probe type before beginning measurements.

(2) Do not damage the probe or get it dirty.

Accurate measurement results cannot be obtained if the chip on the tip of the probe is damaged or dirty. Do not pound the probe against the measurement surface or move the probe laterally while it is pressed down upon the surface. When finished making measurements, use a soft cloth wet with benzine or alcohol to clean the tip of the probe.

(3) Handle the calibration foils with care.

The thickness of the calibration foils has been measured v ery precisely. You will not be ab le to obtain accurate measurement results if you use calibration foils which ha ve been scr atched, bent or otherwise damaged. Be particularly careful not to subject the thinnest foil, the 10µm foil, to wear. If a standard foil becomes damaged while being used, please contact the dealer from whom you purchased the tester and order a replacement of the same thickness. Although the thickness of replacement foils may slightly different than that of the original foils, this does not pose a problem for calibration adjustments.

Caution

(4) Replace the batteries immediately if the low-voltage indicator is displayed.

When the batteries become weak, a "BAT" indicator will appear in the display when the power is first turned on or while the tester is in use. Immediately replace the batteries with 4 new size AA alkaline batteries when this indicator is displayed. Please note that calibration adjustments are maintained in the unit's non-volatile memory even when the batteries are exhausted.

(5) Adjustment & Inspection

In order to maintain precise performance the coating thickness testers should be inspected at least once per year. Please contact the merchant from whom you purchasd your unit regarding inspection.
