Setup

The Pacific Arc Metric Scholastic Scale Ruler requires no assembly or complex setup. It is ready for immediate use upon unboxing.

1. Unpack: Carefully remove the ruler from its packaging.
2. Inspect: Check the ruler for any visible damage or defects. If any are found, contact customer support.
3. Clean (Optional): Wipe the ruler with a soft, dry cloth to remove any dust or residue from manufacturing or packaging.

Operating Instructions

Using your metric scale ruler effectively involves understanding its scales and applying them correctly to your drawings.

Understanding the Scales

The ruler features six different metric scales, each represented on one of its three faces. Each face typically has two scales, one on each edge. The scales are:

• 1:500
• 1:1000
• 1:1250
• 1:1500
• 1:2000
• 1:2500

The ratio (e.g., 1:500) indicates that one unit on the ruler represents 500 units in real life. For example, on the 1:500 scale, 1 centimeter on the ruler represents 500 centimeters (or 5 meters) in the actual object or structure being drawn.

Making Measurements

1. Identify Required Scale: Determine the scale of the drawing or the scale you need to apply for your measurement.
2. Select Ruler Face: Rotate the triangular ruler until the desired scale is facing upwards and is easily accessible. The color-coded grooves can help in quick identification.
3. Align Ruler: Place the ruler firmly on your drawing surface, aligning the zero mark of the selected scale with the starting point of the line or object you wish to measure.
4. Read Measurement: Read the value on the scale at the endpoint of the line or object. This value directly corresponds to the real-world dimension at the chosen scale.
5. Drawing Lines: When drawing, use the selected scale to mark points that correspond to real-world dimensions, then connect them to create scaled representations.

Care and Maintenance

Proper care will extend the life and maintain the accuracy of your Pacific Arc Metric Scholastic Scale Ruler.

• Cleaning: Wipe the ruler regularly with a soft, lint-free cloth. For stubborn marks, a slightly damp cloth with mild soap can be used, followed by immediate drying. Avoid abrasive cleaners or solvents, as they can damage the acrylic and markings.
• Storage: Store the ruler in a clean, dry place, away from direct sunlight or extreme temperatures. Keeping it in a protective sleeve or case can prevent scratches and damage.
• Handling: While durable, avoid dropping the ruler or subjecting it to excessive force, which could cause cracks or deformities.
• Avoid Chemicals: Do not expose the ruler to harsh chemicals, paints, or glues for prolonged periods, as these may stain or degrade the material.

Troubleshooting

This section addresses common questions or minor issues you might encounter.

Issue: Markings appear faded or unclear.

Solution: Ensure the ruler is clean. Dust, pencil lead, or other debris can accumulate in the engraved markings, making them difficult to read. Use a soft brush or a slightly damp cloth to clean the grooves thoroughly.

Issue: Ruler slides easily on the drawing surface.

Solution: Ensure both the ruler and the drawing surface are clean and free of dust or oily residues. Apply firm, even pressure when holding the ruler in place during measurements or drawing.

Issue: Difficulty finding the correct scale.

Solution: Familiarize yourself with the color-coded grooves and the scale markings on each face. Practice rotating the ruler to quickly locate the desired scale. Over time, this will become intuitive.
