IWAVE WH-81 Coating Thickness Gauge magnetic thickness measurement method 0~1250μm

Introduction

IWave coating Thickness Gauge WH-81 has two models: single iron base and iron and aluminum double base, which respectively adopts magnetic thickness measurement method and magnetic eddy current dual-purpose thickness measurement method, which can quickly and accurately detect the thickness of the coating without destructiveness, and the applicable thickness measurement range is 0~1250 microns. WH-81 coating Thickness Gauge is an all-in-one probe Thickness Gauge, small size, very easy to carry, can be used in the laboratory or engineering site, in the manufacturing industry, metal processing industry, automotive industry, chemical industry, commodity inspection and other fields are widely used, such as spraying, painting, oxide film, electroplating, etc. WH-81 (single iron-based/iron-aluminum double-base) coating Thickness Gauge conforms to GB/T 4956-1985, GB/T 4957-1985, JB/T 8393=1996, JJG 889-95, JJG 818-93 and other standards.

Features

1. The WH-81 coating Thickness Gauge adopts two thickness measurement methods, magnetic and eddy current, which can measure the thickness of the non-magnetic covering layer on the magnetic metal collective and the thickness of the non-conductive covering layer on the non-magnetic metal matrix.

2. The coating Thickness Gauge can be calibrated by two methods: single-point calibration and two-point calibrationWH-81 Coating Thickness GaugeCalibration is carried out, and the systematic error of the measuring head can be corrected by the basic calibration method to ensure that the instrument is in the measurement processWH-81 Coating Thickness Gaugeaccuracy;

3、It can quickly and automatically identify ferrous and non-ferrous substrates;

4、WH-81 Coating Thickness GaugeIt has the function of power supply under-Voltage indication;

5、There is a beep prompt during the operation;

6、There are two shutdown modes: manual shutdown mode and automatic shutdown mode;

7、There is a negative number display function, guaranteedWH-81 Coating Thickness Gaugecalibration accuracy at the zero site;

8、There is a function to display the average, maximum, and minimum values.

buttons and display instructions

1) The operation panel of the WH-81 coating Thickness Gauge is a bear shape, from left to right, from top to bottom the buttons are as follows:

How to use:

1) Power on

After pressing the "ON" button, the WH-81 coating Thickness Gauge emits a beep, which will automatically restore the parameter settings before the last shutdown and display 0.0μm, indicating that the WH-81 coating Thickness Gauge has entered the pending state. Now it's time to measure the workpiece to be measured. If the WH-81 coating gauge is not used for a period of time, it will automatically shut down.

2) Shut down

In the absence of any operation, the WH-81 Coating Thickness Gauge automatically shuts down after approximately 3 minutes. Press the "ON" button once to power off immediately.

3) Unit Conversion (Metric to Imperial Conversion)

 In the state to be measured, the WH-81 coating Thickness Gauge is measured in μm/mil convertible.

4) Measurement

a) Prepare the artifact to be tested

b) Determine if calibration of the WH-81 coating Thickness Gauge is required and, if so, select the appropriate calibration method

c) Quickly put the measuring head perpendicular to the test surface and gently press the measuring head positioning sleeve, a beep, the screen displays the measured value, and the WH-81 coating Thickness Gauge will automatically sense the substrate to be measured: when it is a magnetic substrate, the WH-81 coating Thickness Gauge will show Fe, and when it is a non-magnetic metal, the WH-81 coating Thickness Gauge will show NFe. (Iron-aluminum bi-base type can be automatically recognized, single-iron-based type can only measure magnetic substrates)

Note: Keep the WH-81 Coating Thickness Gauge vertical while measuring. When the measuring head is lifted, the next coating measurement can be taken;

Troubleshooting methods

1) Replace the battery

If the WH-81 coating Thickness Gauge is not used for more than 5 consecutive days, the battery should be removed. When the WH-81 coating Thickness Gauge has a low Voltage prompt, the battery should be replaced, and the polarity should be paid attention to when replacing the battery.

2) Factory reset

In the power-on state, press the button, ▲, ▲, ▼, ▼ in order within 2 seconds, and the screen will display an English dialogue asking whether to confirm the factory reset, to restore the factory settings, select "<Yes>" and press μm/mil to confirm.

3) Calibration correction of the measuring head

If there is a large error (such as: improper calibration or operation error, etc.), a six-point correction calibration can be made to calibrate the WH-81 coating Thickness Gauge.
