- Main Unit (TM-5000/TM-5010E): Features a 6-digit LCD display, measurement buttons, and input key.
- TM-4015 Remote Sensor: Used for non-contact measurements in difficult-to-reach locations. Connects to the sensor probe input on the main unit.
- In-Contact Adapter: Attaches to the main unit for contact measurements.
- Rubber Tip: Used with the contact adapter for rotational speed measurements.
- Surface Speed Wheel: Used with the contact adapter for linear speed measurements (e.g., m/min, cm/s). Available in 1/10m or 1/10y circumference.
- Photodetector Part: Located on the main unit for non-contact measurements.
- Display Unit: Shows measured values, units, battery alarm, and memory indicators.
5. Setup
5.1. Battery Installation
- Locate the battery compartment cover on the back of the TM-5000 unit.
- Slide or unclip the cover to open it.
- Insert four (4) AAA alkaline batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Replace the battery compartment cover securely.
Note: The device uses 4 pieces of AAA Alkaline Battery. Continuous measurement is approximately 20 hours.
5.2. Attaching Accessories
Depending on the measurement method, attach the appropriate accessory:
- For Contact Measurement:
- Attach the in-contact adapter to the main unit.
- Select either the rubber tip (for rotational speed) or the surface speed wheel (for linear speed) and securely attach it to the in-contact adapter.
- For Remote Sensor Non-Contact Measurement:
- Connect the TM-4015 Remote Sensor cable to the sensor probe input jack on the main unit.
- Ensure the connection is firm.
6. Operating Instructions
6.1. Powering On/Off
Press the POWER button to turn the tachometer on. The display will illuminate. The unit features an auto-power-off function that activates after 3 minutes of inactivity to conserve battery life.
6.2. Measurement Method Selection
The TM-5000 supports both non-contact and contact measurement methods. The method is typically selected automatically based on whether a contact adapter is attached or if the remote sensor is active.
- Non-Contact Measurement:
For non-contact measurements, ensure the contact adapter is removed. Apply a piece of reflective tape to the rotating object. Point the photodetector part of the main unit (or the remote sensor) at the reflective tape from a suitable distance. The display will show the rotational speed.
- Contact Measurement:
Attach the in-contact adapter with either the rubber tip or surface speed wheel. Gently press the tip or wheel against the rotating shaft or surface. The display will show the rotational or linear speed.
6.3. Unit Conversion
The TM-5000 allows for instant conversion of measured values to different units. Use the UNIT button (if available, or refer to specific model buttons) to cycle through available units: RPM, RPS, m/min, cm/s, inch/s, ft/min, and yd/min. The selected unit will be displayed on the LCD.
6.4. Data Storage and Recall
The tachometer can store up to 8 measured values. To store a value, press the MEM button (or equivalent). To recall stored values, press the RECALL button (or equivalent) and use navigation buttons to browse through the memory. The display will indicate the memory number (e.g., MEM-1).
The unit also displays MIN/MAX values during measurement. These are automatically updated and can be viewed by pressing the appropriate button (e.g., MIN/MAX).
7. Maintenance
- Cleaning: Wipe the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: When the battery alarm appears on the display, replace all four AAA batteries promptly to ensure accurate readings and prevent data loss.
- Storage: Store the tachometer in its carrying case in a cool, dry place when not in use for extended periods. Remove batteries if storing for several months.
- Contact Adapters: Inspect the rubber tip and surface speed wheel for wear or damage. Replace if necessary to maintain measurement accuracy.
- Reflective Tape: Ensure reflective tape is clean and securely applied for non-contact measurements.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or unit does not power on. | Dead or incorrectly installed batteries. | Check battery polarity. Replace with new AAA alkaline batteries. |
| "Battery alarm" displayed. | Low battery power. | Replace all four AAA batteries. |
| Inaccurate or unstable readings (Non-Contact). | Insufficient reflective tape, improper distance/angle, ambient light interference. | Ensure reflective tape is clean and properly applied. Adjust distance and angle to the target. Minimize strong ambient light. |
| Inaccurate or unstable readings (Contact). | Worn rubber tip/surface wheel, insufficient contact pressure, slippage. | Inspect and replace worn contact accessories. Apply firm, consistent pressure. Ensure no slippage during measurement. |
| "Measurement data: Until the next data is defined" message. | Indicates no new measurement data has been recorded since the last data hold or memory recall. | Initiate a new measurement to update the display. |
