5. Setup

5.1 Battery Installation

1. Locate the battery compartment on the rear of the device.
2. Slide the battery compartment cover downwards to open.
3. Insert two AA 1.5V alkaline batteries, ensuring correct polarity (+/-).
4. Replace the battery compartment cover, sliding it upwards until it clicks into place.

5.2 Probe Connection

1. Identify the two probe connection ports on the side of the MT160 unit.
2. Connect the two plugs from the ultrasonic probe cable into these ports. Ensure a firm connection.

6. Operation

6.1 Power On/Off

Press the red circular button once to power on the device. To power off, press and hold the same button until the display turns off. The device also features auto sleep and auto power off functions to conserve battery life.

6.2 Basic Measurement

1. Ensure the probe is connected and the device is powered on.
2. Apply a small amount of coupling agent to the surface of the material to be measured. This eliminates air gaps between the probe and the material, which would interfere with ultrasonic wave transmission.
3. Place the probe firmly and flatly onto the prepared surface.
4. The LCD display will show the thickness reading. The coupling status indicator will confirm proper contact.
5. Remove the probe from the surface after the reading stabilizes.

6.3 Calibration

Calibration is crucial for accurate measurements. The MT160 allows for calibration using a known thickness or by measuring sound speed.

1. Press the CAL button to enter calibration mode.
2. Follow the on-screen prompts to calibrate using a material of known thickness or by inputting the sound velocity.
3. Confirm the calibration settings.

6.4 Unit Selection

Press the IN/MM button to toggle between Metric (millimeters) and Imperial (inches) units for your measurements.

6.5 Scan Mode

For continuous measurement and to find the minimum thickness over an area, use the Scan Mode.

1. Press the SCAN button to activate Scan Mode.
2. Move the probe across the surface. The device will continuously update the display with readings (ten per second).
3. Press the SCAN button again to exit Scan Mode.

6.6 Memory Functions

The MT160 can store up to 20 files, with each file containing up to 99 values.

• Use the designated memory button (often indicated by a folder icon or similar) to save readings.
• Navigate through stored files and values using the arrow buttons.

6.7 Indicators

• Coupling Status Indicator: Displays the quality of contact between the probe and the material. A stable indicator means good coupling.
• Remaining Battery Indicator: Shows the current battery level in real-time.

7. Maintenance

7.1 Cleaning

• After each use, wipe the probe and the device with a soft, dry cloth to remove any coupling agent residue or dirt.
• Do not use abrasive cleaners or solvents, as these can damage the device's surface or display.

7.2 Storage

• Store the MT160 in its hard carrying case when not in use to protect it from dust, moisture, and physical damage.
• If storing for an extended period, remove the batteries to prevent leakage.
