4. Setup
Follow these steps to set up your INSIZE 1124-300A Electronic Caliper:
4.1. Battery Installation
The caliper uses a CR2032 battery. If the display does not turn on or is dim, replace the battery. Locate the battery compartment cover on the digital unit, slide it open, insert the new CR2032 battery with the positive (+) side facing up, and close the cover securely.
4.2. Attaching Interchangeable Points
The caliper comes with various interchangeable points for different measurement tasks. To attach a point:
- Select the appropriate pair of points for your measurement.
- Carefully align the points with the mounting slots on the caliper jaws.
- Securely fasten the points using the provided screws or locking mechanism. Ensure they are firmly attached to prevent movement during measurement.
The included points are:
- Spherical points: Used for measuring small holes.
- Flat points: Used for measuring external grooves.
- Blade points: Used for measuring narrow grooves.
4.3. Zero Setting
Before taking measurements, it is crucial to set the caliper to zero. This ensures accuracy.
- Ensure the caliper jaws are clean and free of debris.
- Bring the measurement faces of the caliper together (or against the zero setting block for external measurements).
- Press the "SET" button. The display should read "0.0000" or "0.00". If not, repeat the process.

5. Operating Instructions
5.1. Power On/Off
- To turn on the caliper, press the "ON/OFF" button or simply move the digital unit along the beam.
- To turn off the caliper, press the "ON/OFF" button. The caliper also features an automatic power-off function after a period of inactivity to conserve battery life.
5.2. Unit Conversion (Inch/mm)
To switch between inch and millimeter units, press the "INCH/MM" button. The display will instantly convert the reading to the selected unit.
5.3. Preset Function
The preset function allows you to set a specific starting value for your measurements. This is useful for comparative measurements or when measuring from a known reference point.
- Move the caliper jaws to the desired starting position.
- Press the "PRESET (+)" or "PRESET (-)" button to adjust the displayed value to your desired preset.
- Subsequent measurements will be relative to this preset value.
5.4. Taking Measurements
Ensure the caliper is clean and zeroed before each measurement.
- External Measurement: Place the object between the external jaws. Gently close the jaws until they make firm contact with the object. Read the value on the digital display.
- Internal Measurement: Use the internal jaws (the smaller jaws on top). Insert them into the opening to be measured and expand them until they make firm contact with the inner surfaces. Read the value.
- Depth Measurement: Extend the depth rod from the end of the caliper into the hole or step. Rest the end of the main beam on the surface and extend the rod until it touches the bottom. Read the value. (Note: An optional depth stop, model 6143, can enhance depth measurement stability).
5.5. Data Output
The caliper is equipped with a data output port. To connect to a data collection system, use an optional data output cable (e.g., 7302-SPC5A, 7305-SPC2A). Refer to the cable's instructions for specific connection and software requirements.
6. Maintenance
Proper maintenance will ensure the longevity and accuracy of your INSIZE Electronic Caliper.
- Cleaning: After each use, wipe the caliper clean with a soft, lint-free cloth. For stubborn dirt, use a mild, non-abrasive cleaner. Avoid using solvents that could damage the electronic components or the finish.
- Lubrication: Occasionally apply a thin coat of light machine oil to the sliding surfaces to ensure smooth operation and prevent corrosion.
- Battery Replacement: Replace the CR2032 battery when the display becomes dim or does not turn on. Dispose of old batteries responsibly.
- Storage: Store the caliper in its original hard plastic blow mold case when not in use. Keep it in a dry, clean environment, away from direct sunlight, extreme temperatures, and magnetic fields.
- Inspection: Periodically inspect the caliper for any signs of damage, wear, or misalignment. If any issues are found, contact customer support or a qualified technician for repair.
The caliper is made of stainless steel, which provides good corrosion resistance, but proper care is still essential.
7. Troubleshooting
If you encounter issues with your caliper, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Low or dead battery. | Replace the CR2032 battery. |
| Display shows erratic readings or "Error". | Dirt or debris on the measuring surfaces or beam; electromagnetic interference. | Clean the caliper thoroughly. Move away from strong electromagnetic fields. Try resetting by removing and reinserting the battery. |
| Caliper does not zero correctly. | Dirt between jaws; jaws not fully closed; mechanical damage. | Clean jaws thoroughly. Ensure jaws are fully closed before pressing "SET". Inspect for damage. |
| Jaws do not slide smoothly. | Lack of lubrication; dirt on the beam. | Clean the beam and apply a thin layer of light machine oil. |
If the problem persists after attempting these solutions, please contact INSIZE customer support for further assistance.
