CHOOSING THE MEASURING RANGE
300mm Model
For components requiring up to 300mm measuring capacity with the listed 100mm lower jaw dimension.
500mm and 600mm Models
For larger components, with a choice of 100mm or 150mm lower jaw dimensions.
1000mm Models
For components requiring up to 1000mm capacity, with 150mm or 200mm lower jaw dimensions.
1500mm Model
For large components requiring up to 1500mm capacity, with a listed 150mm lower jaw dimension.
Maximum opening alone does not determine suitability. Check the measuring contact location, available clearance and the accuracy required by the inspection task.
WHY JAW LENGTH MATTERS
Longer jaws can help reach measuring surfaces that are set back from the edge of a component.
For example, the 106-500/100 and 106-500/150 both have a 0–500mm measuring range, but different lower jaw dimensions. The correct choice depends on where the jaws must contact the workpiece.
Jaw length is not a guarantee of usable recess depth. Jaw shape, component geometry and surrounding obstructions must also be checked.
For the 1000mm models, the catalogue lists different accuracy values:
• 106-1000/150: ±0.07mm.
• 106-1000/200: ±0.08mm.
OUTSIDE AND INSIDE MEASUREMENT
Outside Measurement
Use the appropriate lower measuring faces to check accessible external dimensions, including outside diameter and width.
Inside Measurement
Use the upper inside jaws for accessible internal dimensions. Confirm the minimum measurable opening and the correct reading method from the manufacturer’s instructions.
Recessed Feature Measurement
The extended lower knife-edge jaws can reach suitable recessed measuring surfaces where a shorter jaw cannot make contact. Confirm suitability using a component drawing or sample.
Do not assume that depth or step measurement functions are included. These functions are not specified on the supplied catalogue page.
APPLICATIONS IN MALAYSIA
The DITRON 106 series can be considered for dimensional checks involving:
• Large machined components.
• Fabricated rings and frames.
• Accessible flange and housing dimensions.
• Maintenance and replacement-part assessment.
• Incoming inspection of larger components.
• Recessed features requiring additional jaw reach.
For engineering workshops and fabrication facilities in Selangor, Kuala Lumpur, Johor and Penang, model selection should be based on the actual component geometry and tolerance.
RESOLUTION AND ACCURACY
All listed models have a vernier resolution of 0.02mm. This is the reading increment, rather than a guarantee of ±0.02mm accuracy.
Catalogue-stated accuracy varies from ±0.04mm to ±0.11mm across the listed models.
For large workpieces, instrument support, alignment, measuring force and temperature are particularly important. Assess whether the selected caliper meets the inspection requirement before using it for acceptance decisions.
BASIC MEASURING PROCEDURE
1. Clean the measuring faces and workpiece.
2. Check the zero alignment and slider movement.
3. Support the caliper and workpiece securely.
4. Position the correct measuring faces against the feature.
5. Keep the instrument aligned with the dimension being measured.
6. Apply light, consistent contact force.
7. Read the main scale and aligned vernier graduation.
8. Repeat the measurement to assess consistency.
Avoid using the long jaws as levers or forcing them against the workpiece.
CARE AND STORAGE
• Keep the scale and sliding surfaces clean.
• Remove chips before bringing the measuring faces together.
• Avoid impact and excessive force on the jaws.
• Clean and dry the instrument after use.
• Follow the manufacturer’s maintenance instructions.
• Store with adequate support to protect the beam and jaws.
• Check performance against suitable reference standards according to your quality procedure.
FREQUENTLY ASKED QUESTIONS

What does 106-500/150 mean?
The catalogue lists this model with a 0–500mm measuring range and a 150mm jaw dimension a.
Are all models equally accurate?
No. Accuracy varies by model. Check the individual specification before selecting.
Do longer jaws provide better accuracy?
Not necessarily. Longer jaws provide additional reach. The catalogue lists ±0.07mm for the 106-1000/150 and ±0.08mm for the 106-1000/200.
Can the 106 series measure inside dimensions?
Yes. The catalogue includes upper inside measuring jaws and describes OD and ID measurement.
Can it measure recessed features?
The catalogue describes extended lower knife-edge jaws for suitable recessed features. Confirm that the jaw geometry can reach the intended measuring surfaces.
Does it require a battery?
No. It uses a mechanical main scale and vernier readout.
Can it measure depth?
A depth measurement function is not specified on the supplied page.
Is a calibration certificate included?
The supplied page does not confirm that an individual calibration certificate is included. Specify documentation requirements when requesting a quotation.
