INSTRUCTION MANUAL MT155 COATING THICKNESS METER

Introduction

The MT155 Coating Thickness Meter measures non-magnetic coatings (e.g. paint, zinc) on steel and insulating coatings (e.g. paint  anodizing coatings) on non-ferrous metals. It has a user-friendly  MENU, memory for 1500 readings, error indication, and data transfer to PC via USB for analysis. It also has a disable Auto-Power-off function via MENU setting, LCD display with backlight, and V-Groove sleeve.

Usage Instructions

Ready to Start

To power on the device, press and hold the POWER button. If the LCD display does not switch on, check if the battery is correctly installed or flat. If displayed: “Low battery, replace battery immediately”. The gauge will take faulty measurements if the voltage is low. Note: When the power is on, keep away from any metal at least 10cm away before each measurement, zero calibration is recommended.

Inserting/Replacing Batteries

1. Switch off the tester, remove the battery cover and remove batteries.
2. Insert new batteries, observing correct polarity and close the cover.
3. Be aware of the danger of corrosion.

Introduction

Thank you for your purchase of the Coating Thickness Tester. The MT155 is a compact and handy gauge specifically designed for non-destructive, fast and precise coating thickness measurements. The principal application is for corrosion protection. It is ideal for manufacturers, for offices, specialist advisers, for paint shops, electroplaters, for the chemical, automobile, shipbuilding, aircraft industries and for light or heavy engineering. The gauge is suitable for laboratory, workshop or outdoor use. The probe can work on both principles, magnetic induction or the eddy current principle. Only 1 (one) probe is required for coating measurement both on ferrous and non- ferrous metal substrates. It is adaptable to specific tasks for instance they can be used on special geometries or on materials with special properties. You can select the probe mode via the MENU system.

Features

• Measured Coatings:
  • Non-magnetic coatings (e.g. paint, zinc) on steel;
  • Insulating coatings(e.g. paint, anodizing coatings) on no-ferrous metals

• Memory for 1500 readings
• Delete single readings or all group readings
• Error indication
• Data transferred to PC via USB for analysis
• Disable Auto-Power-off function via MENU setting
• LCD display with backlight
