4. Product Overview

4.1. Components

• Indicator Body: Houses the electronic components and display.
• Spindle/Plunger: The movable rod that extends and retracts to measure displacement.
• Stem: The cylindrical part used for mounting the indicator, typically 3/8" diameter.
• Probes: Interchangeable tips attached to the end of the spindle for contacting the workpiece.
• Back Plate: The rear attachment point, which can be a flat back or a lug back for mounting.

4.2. Controls and Display

• LCD Display: Extra large screen showing measurement readings, units (inch/mm), and mode (INC/ABS).
• TOL Button: (Tolerance) Used for setting tolerance limits (refer to advanced operations if applicable, not detailed in basic product info).
• mm/inch Button: Switches between millimeter and inch measurement units.
• ON/OFF Button: Powers the indicator on or off.
• ZERO Button: Sets the current position as the zero reference point for incremental measurements.
• ABS/INC Button: Toggles between Absolute and Incremental measurement modes.

5. Setup

5.1. Battery Installation

The indicator comes with a pre-installed battery and an extra battery. If replacement is needed:

1. Locate the battery compartment cover on the back of the indicator.
2. Carefully remove the cover.
3. Insert a new CR2032 lithium coin cell battery with the positive (+) side facing up.
4. Replace the battery compartment cover securely.

5.2. Mounting the Indicator

The indicator can be mounted using its 3/8" stem or by attaching the lug back to a compatible fixture, such as a magnetic base.

1. For Stem Mounting: Insert the 3/8" stem into a suitable clamp or holder on your measurement stand or fixture. Secure it firmly without overtightening.
2. For Lug Back Mounting: If the flat back is installed, remove it by unscrewing the small screws. Attach the included lug back using the same screws. Then, mount the lug back onto a compatible magnetic base or fixture.
3. Ensure the indicator is stable and securely positioned to prevent movement during measurement.

6. Operating Instructions

6.1. Power On/Off

• Press the ON/OFF button to turn the indicator on.
• Press and hold the ON/OFF button for a few seconds to turn the indicator off.

6.2. Zero Setting

The ZERO function allows you to set any point as your reference zero for incremental measurements.

1. Position the probe at the desired reference point on your workpiece or fixture.
2. Press the ZERO button. The display will show "0.0000" (or "0.00" in mm), and subsequent movements will be measured relative to this point.

6.3. Inch/Metric Conversion

To switch between inch and millimeter units:

• Press the mm/inch button. The display will toggle between "in" (inches) and "mm" (millimeters).

6.4. Absolute (ABS) and Incremental (INC) Measurement

The indicator supports two measurement modes:

• Absolute (ABS) Mode: Measures the distance from a fixed, absolute zero point (usually the fully retracted position of the spindle). This mode is useful for measuring overall dimensions from a datum.
• Incremental (INC) Mode: Measures the distance from the last zeroed position. This mode is useful for measuring differences or steps between features.

To switch between modes:

• Press the ABS/INC button. The display will indicate "ABS" or "INC" to show the current mode.

6.5. Using Probes

The indicator comes with four interchangeable probes for various applications:

• Carbide Ball Probe: General purpose, durable for most surfaces.
• Large Flat Probe: Ideal for measuring flat surfaces or large contact areas.
• Small Flat Probe: Suitable for smaller flat surfaces or confined areas.
• Point Probe: Used for precise contact on small features, holes, or scribed lines.

To change a probe:

1. Gently unscrew the currently installed probe from the end of the spindle.
2. Carefully screw the desired probe onto the spindle until it is finger-tight. Do not overtighten.
3. After changing probes, it is recommended to re-zero the indicator if working in incremental mode.

7. Maintenance

7.1. Cleaning

• Wipe the indicator body and spindle with a clean, soft, lint-free cloth.
• For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by immediate drying.
• Do not use harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish or electronic components.
• Ensure no liquid enters the display or button areas.

7.2. Storage

• Always store the indicator in its protective case when not in use.
• Store in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.
• Keep out of reach of children.

7.3. Battery Replacement

When the display becomes dim or erratic, it's time to replace the battery. Refer to Section 5.1 for battery installation instructions. Dispose of old batteries responsibly according to local regulations.
