Imada Analog Mechanical Force Gauge User Manual

1. Introduction

This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your Imada Analog Mechanical Force Gauge. This device is designed for precise measurement of push and pull forces up to 100 lbs, offering reliability and ease of use without requiring external power.

2. Safety Information

Always read and understand all instructions before operating the force gauge. Failure to follow safety guidelines may result in injury or damage to the instrument.

• Do not exceed the maximum rated capacity of 100 lbs. The overload capacity is 165 lbs, but continuous operation beyond 100 lbs can affect accuracy and lifespan.
• Ensure the gauge is securely held or mounted during testing to prevent accidental drops or impacts.
• Avoid applying sudden shock loads, which can damage the internal mechanism.
• Keep the instrument clean and free from dust, moisture, and corrosive substances.
• This device is intrinsically safe in hazardous environments as it requires no batteries or external power.

3. Product Overview

The Imada Analog Mechanical Force Gauge is a robust and reliable instrument for various force measurement applications. Its design emphasizes durability and accuracy.

Key Features:

• Simple, Rugged Design: Built for longevity and minimal maintenance.
• High Accuracy: Retains a high degree of accuracy (0.3% FS) over extended periods.
• Ergonomic Construction: Heavy-duty metal construction for comfortable and secure handling.
• No Batteries Needed: Operates mechanically, making it suitable for environments where electrical devices are restricted.
• Push and Pull Measurement: Measures forces in both compression (push) and tension (pull).
• Real Time and Peak Mode: Allows for instantaneous readings and capturing the maximum force applied.
• Tare Ring: A rotational ring on the analog dial for zeroing the reading.
• Accessories: Includes a full set of accessories and a carrying case for convenience.

4. Setup

1. Unpacking: Carefully remove the force gauge and all accessories from its carrying case. Inspect for any signs of damage during transit.
2. Accessory Attachment: Select the appropriate attachment (e.g., flat head, hook, chisel) for your specific measurement application. Securely screw the attachment onto the threaded shaft at either the 'PULL' or 'PUSH' end of the gauge.
3. Initial Check: Before first use, gently apply a small force to the gauge to ensure the needle moves smoothly and returns to zero when the force is removed.
4. Zero Adjustment (Tare): If the needle does not rest precisely at zero, rotate the tare ring on the analog dial until the needle aligns with the zero mark.

5. Operating Instructions

5.1. Basic Force Measurement (Real Time Mode)

1. Ensure the gauge is zeroed using the tare ring.
2. For Push (compression) measurements, apply force to the 'PUSH' end of the gauge. For Pull (tension) measurements, apply force to the 'PULL' end.
3. Apply force smoothly and gradually. Read the current force value directly from the analog dial as the needle moves.
4. Once the force is removed, the needle will return to zero.

5.2. Peak Mode Measurement

The gauge is equipped with a peak hold feature, allowing it to retain the maximum force applied during a test.

1. Before starting, ensure the peak hold needle (often a secondary, black needle) is reset to zero by rotating the knob on the side of the gauge.
2. Apply force as described in Section 5.1. The main needle will move with the applied force, and the peak hold needle will follow, stopping at the maximum force reached.
3. After the test, remove the force. The main needle will return to zero, but the peak hold needle will remain at the maximum value.
4. Record the peak value. To reset for the next measurement, rotate the side knob to bring the peak hold needle back to zero.

6. Maintenance

Proper maintenance ensures the longevity and accuracy of your force gauge.

• Cleaning: Wipe the exterior of the gauge with a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild soap can be used, ensuring no moisture enters the internal mechanism. Do not use abrasive cleaners or solvents.
• Storage: Store the gauge in its original carrying case in a dry, clean environment, away from extreme temperatures, humidity, and direct sunlight.
• Calibration: While the gauge is designed to retain accuracy, periodic calibration by a qualified technician is recommended, especially for critical applications or after significant use. Refer to the manufacturer's recommendations for calibration intervals.
• Inspection: Regularly inspect the gauge for any signs of physical damage, loose parts, or unusual needle movement.
