సెటప్ మరియు ప్రారంభ తయారీ
1. బ్యాటరీ ఇన్స్టాలేషన్
The GM100 requires three AAA batteries for operation. Ensure correct polarity when inserting the batteries into the compartment located on the back of the device.
- Open the battery cover on the rear of the unit.
- Insert 3 AAA batteries, observing the polarity markings (+/-).
- బ్యాటరీ కవర్ను సురక్షితంగా మూసివేయండి.

2. ప్రోబ్ కనెక్షన్
Connect the ultrasonic probe to the designated ports on the top of the GM100 unit. Ensure the connectors are firmly seated.
3. Applying Coupling Fluid
A coupling fluid (gel) is essential for accurate measurements. It facilitates the transmission of ultrasonic waves between the probe and the material being measured. Apply a small amount of coupling fluid to the surface of the material where the probe will be placed.
- కొలత ఉపరితలం శుభ్రంగా మరియు శిధిలాలు లేకుండా ఉందని నిర్ధారించుకోండి.
- Apply a small drop of coupling gel to the surface.
- Press the probe firmly onto the gelled surface to ensure good contact.
ఆపరేటింగ్ సూచనలు
1. పవర్ ఆన్/ఆఫ్
నొక్కండి శక్తి బటన్ (
) to turn the device on. The device will automatically power off after a period of inactivity to conserve battery life.
2. క్రమాంకనం
Before taking measurements, it is recommended to calibrate the device using the built-in metal calibration block or the included 4mm calibration block.
- Apply coupling fluid to the calibration block.
- Press the probe firmly onto the calibration block.
- నొక్కండి CAL బటన్ () to perform zero-point calibration. The device will automatically adjust to correct system errors.
3. Measuring Thickness
Once calibrated, apply coupling fluid to the material surface and press the probe firmly against it. The thickness reading will appear on the LED backlit screen. The device measures in both inches and millimeters.

4. Adjusting Sound Velocity (VEL)
Different materials have different sound velocities. For accurate measurements, adjust the sound velocity setting to match the material being tested. The GM100 allows adjustment from 1000 to 9999 m/s.
- నొక్కండి VEL బటన్ () to enter sound velocity adjustment mode.
- బాణం కీలను ఉపయోగించండి ( / ) to increase or decrease the value.
- Refer to the material sound velocity table below for common materials.
- The device also supports a reverse measurement ability: if you have a material sample of known thickness but unknown type, you can input the thickness, and the unit will derive the sound velocity, allowing you to identify the material or measure other items of the same type.

5. డేటా నిల్వ మరియు రీకాల్
The GM100 can store up to 10 thickness values and 12 sound velocity values.
- To store a reading, press the స్టోర్ బటన్ ().
- To recall stored data, use the Function Switch Key () and arrow keys to navigate through the memory slots.

నిర్వహణ
1. శుభ్రపరచడం
After each use, wipe the probe and the device's surface with a soft, dry cloth to remove any residual coupling fluid or dirt. Do not use abrasive cleaners or solvents.
2. నిల్వ
Store the GM100 in its protective case in a cool, dry place when not in use. Remove batteries if the device will not be used for an extended period to prevent leakage.
3. Coupling Fluid
Ensure you have an adequate supply of ultrasonic coupling gel. The device will not function correctly without it. Replacements can be sourced from reputable suppliers.
ట్రబుల్షూటింగ్
If you encounter issues with your GM100, refer to the following common problems and solutions:
- చదవడం లేదు లేదా అనియత రీడింగ్లు:
- Ensure sufficient coupling fluid is applied and there are no air bubbles.
- Verify the probe is pressed firmly and evenly against the surface.
- Check if the material surface is too rough or has non-parallel top and bottom surfaces (see Figure 5 reminders).
- Confirm the material is an ultrasonic wave conductor.
- సరికాని రీడింగ్లు:
- Perform a calibration using the included calibration block.
- Verify the correct sound velocity for the material is selected.
- Ensure the material is not at an extremely high temperature, which can affect readings (see Figure 5 reminders).
- పరికరం పవర్ ఆన్ అవ్వడం లేదు:
- బ్యాటరీ ఇన్స్టాలేషన్ను తనిఖీ చేయండి మరియు బ్యాటరీలు ఖాళీ కాలేదని నిర్ధారించుకోండి. అవసరమైతే భర్తీ చేయండి.
- Sound Velocity Readout Issues:
- While the device is designed to allow sound velocity measurement for unknown materials, ensure you are following the specific steps outlined in the operating instructions for this advanced function.
