401-100 — COMPACT DIGITAL CALIPER
The DITRON 401-100 is the smallest model listed on this catalogue page. Its 0–100mm range can suit smaller components and portable dimensional checks where a larger caliper is unnecessary.
The catalogue lists the following drawing dimensions for the 401-100:
a: 29.7mm
b: 16.6mm
c: 12.6mm
d: 170mm
e: 13mm
These dimensions differ from the larger models. Check the manufacturer’s drawing when assessing jaw reach and access around a component.
A compact body does not guarantee access to every restricted feature. Confirm that the measuring faces can contact the required surfaces.
SCREW-SECURED BATTERY COVER
The 401 series features a battery cover secured with a screw. The manufacturer describes this arrangement as helping prevent children from opening the compartment and accidentally swallowing the battery.
Keep the instrument and loose batteries away from children. Refit and secure the battery cover correctly after replacement.
The supplied page does not specify the battery voltage, exact battery code or operating duration. Confirm the correct replacement battery from the operating instructions or supplier.
CHOOSING THE MEASURING RANGE
For smaller components and users who prefer a compact instrument.
For general workshop measurements requiring more capacity than the 100mm model.
For components that exceed a 150mm measuring range.
For larger components requiring up to 300mm capacity.
Select according to the largest dimension being measured, required jaw reach and inspection tolerance. A longer range does not mean higher accuracy.
FOUR MEASUREMENT FUNCTIONS
Outside Measurement
Use the external jaws to check accessible dimensions such as thickness, width and outside diameter.
Inside Measurement
Use the internal jaws to check accessible internal dimensions. Correct jaw alignment is important for consistent readings.
Step Measurement
Use the step measuring faces to check suitable stepped features.
Depth Measurement
Use the depth rod to measure accessible holes or recesses. Keep the reference face seated correctly against the workpiece.
APPLICATIONS IN MALAYSIA
The DITRON 401 series can be considered for:
• General workshop dimensional checks.
• Maintenance and spare-part measurements.
• Incoming component inspection.
• Machining and fabrication checks.
• Assembly measurements.
• Supervised technical training.
The 100mm model can be considered for smaller parts and portable toolkits, provided its measuring capacity and jaw dimensions meet the task.
For workshops and inspection departments in Selangor, Kuala Lumpur, Johor and Penang, choose the model according to the workpiece and required tolerance.
RESOLUTION AND ACCURACY
All listed models have a metric display resolution of 0.01mm. This describes the displayed increment and is different from measurement accuracy.
Catalogue-stated accuracy:
401-100: ±0.02mm
401-150: ±0.02mm
401-200: ±0.03mm
401-300: ±0.04mm
A display reading to two decimal places does not establish ±0.01mm accuracy. Measuring technique, cleanliness, temperature and instrument condition also affect results.
For tight-tolerance inspection, assess whether a micrometer or another measuring instrument is more appropriate.
AUTOMATIC POWER FUNCTIONS
The catalogue lists automatic power-on and automatic power-off after five minutes of inactivity.
These functions support routine use, but the supplied page does not establish battery runtime or reference retention after switching off. Check the zero reading before measurement.
CARE AND BASIC CHECKS
• Clean the measuring faces and workpiece before use.
• Close the jaws gently and check the zero reading.
• Apply light, consistent measuring force.
• Keep the caliper aligned with the dimension being measured.
• Remove chips and residue before closing the jaws.
• Avoid measuring hot or moving components.
• Keep the battery cover correctly secured.
• Check performance against suitable reference standards according to your quality procedure.
The supplied catalogue page does not state an IP protection rating. Confirm suitability before use around water, coolant or heavy contamination.
