HURRISE Model-100 Anti-Static Resistivity Meter User Manual

1. Introduction

The HURRISE Model-100 Anti-Static Resistivity Meter is a precise instrument designed for accurately measuring the surface resistivity and grounding of various materials. This device is essential for evaluating conductive, antistatic, and static dissipative properties, ensuring compliance with industry standards such as ANSI ESD S20.20 and IEC61340-5-1.

Its versatile applications include engineering, maintenance, quality control, incoming inspection, manufacturing, and training environments where static control is critical.

2. Safety Information

Please read and understand all safety instructions before operating the device. Failure to follow these instructions may result in inaccurate readings or damage to the instrument.

• Do not expose the meter to extreme temperatures, humidity, or direct sunlight.
• Avoid dropping the device or subjecting it to severe impacts.
• Ensure the battery compartment is securely closed during operation.
• Do not attempt to open or repair the device yourself. Refer all servicing to qualified personnel.
• Keep the meter clean and free from dust and debris.

3. Product Overview

The HURRISE Model-100 features a clear indicator panel and a simple interface for ease of use. Below is a diagram illustrating the key components of the device.

• Flash Indicator (LEDs): A series of LEDs indicating the measured resistance range, from 10³ to 10¹² Ohms per square. These LEDs are grouped into Conductive, Static Dissipative, and Insulative categories.
• Insulation Indicator Light: A dedicated LED that illuminates when the material being tested is insulative.
• Test Button: A red button used to initiate a measurement.
• Earth Leakage Port: A connection point for an external ground wire to perform grounding tests.
• Model-100 Label: Identifies the specific model of the resistivity meter.
• Resistivity Meter Label: Indicates the primary function of the device.

4. Setup

Before using the HURRISE Model-100, ensure it is properly set up.

4.1 Battery Installation

1. Locate the battery compartment on the back of the meter.
2. Slide open the battery compartment cover.
3. Insert one 9V (6F22) battery, ensuring correct polarity. The device is shipped with a matching battery.
4. Close the battery compartment cover securely.

4.2 Connecting the Ground Wire (Optional)

For specific grounding tests, the included ground wire can be connected.

1. Insert the jack end of the ground wire into the Earth Leakage port on the front of the meter.
2. Connect the alligator clip end of the ground wire to a known ground point or the material being tested for grounding.

5. Operating Instructions

The HURRISE Model-100 utilizes the ASTM standard D 257 parallel grid induction method for precise and high-speed measurements.

5.1 Surface Resistivity Measurement

1. Place the meter directly onto the surface of the material you wish to test. Ensure good contact between the meter's electrodes and the material.
2. Press and hold the red TEST button.
3. Observe the Flash Indicator LEDs. The LED corresponding to the material's surface resistivity will illuminate.
4. Release the TEST button to turn off the indicators.

5.2 Interpreting Results

The illuminated LED indicates the resistance range in Ohms per square (Ω/sq).

• Conductive: LEDs from 10³ to 10⁵ Ω/sq. Materials in this range are highly conductive and allow static charges to dissipate rapidly.
• Static Dissipative: LEDs from 10⁶ to 10¹⁰ Ω/sq. These materials allow static charges to dissipate at a controlled rate, preventing rapid discharge.
• Insulative: LEDs at 10¹¹ Ω/sq and 10¹² Ω/sq, or the dedicated Insulation Indicator Light. Materials in this range resist the flow of static charges and can accumulate them.

5.3 Grounding Measurement (using Earth Leakage Port)

To measure the resistance to ground, connect the ground wire as described in Section 4.2.

1. Connect the alligator clip of the ground wire to the material or object whose resistance to ground you wish to measure.
2. Place the meter on the material, ensuring good contact.
3. Press and hold the red TEST button.
4. Read the illuminated LED indicator to determine the resistance to ground.

6. Maintenance

6.1 Cleaning

Wipe the meter with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the ABS material and electronic components.

6.2 Battery Replacement

When the indicator lights become dim or the meter fails to power on, replace the 9V battery as described in Section 4.1. Remove the battery if the meter will not be used for an extended period to prevent leakage.

6.3 Storage

Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case to prevent damage.

7. Troubleshooting

• Meter does not power on: Check if the 9V battery is installed correctly and has sufficient charge. Replace the battery if necessary.
• Inconsistent or no readings: Ensure the meter's electrodes are making firm and clean contact with the material surface. Clean the electrodes if they appear dirty. Verify the material is suitable for testing.
• Readings affected by humidity: Note that humidity levels above 65%RH can affect the measurement accuracy of the instrument. Perform tests in a controlled environment if precise readings are critical.
