Safety Information

WARNING: Always read and understand all safety warnings and operating instructions before using these instruments. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Both the TSM-522S and TCM-300D are certified for safety with CAT III 600V ratings.
• Ensure the instruments are in good working condition before each use. Do not use if damaged.
• Always wear appropriate personal protective equipment (PPE), such as safety glasses and insulated gloves.
• Do not apply voltage or current that exceeds the maximum rated values specified for the instrument.
• Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
• Before measuring current with the clamp meter, ensure the circuit is de-energized if possible, and isolate the conductor.
• Always disconnect the test leads from the circuit before changing functions or ranges.
• Utilize the Non-Contact Voltage (NCV) feature to detect live wires before making contact.

Setup

1. Unpacking and Contents Check

Carefully unpack all items from the packaging. Verify that all components are present:

• TESMEN TSM-522S Smart Digital Multimeter
• TESMEN TCM-300D Smart Digital Clamp Meter
• Test Leads (for TSM-522S and TCM-300D)
• Storage Bag
• Temperature Probe Pens
• Batteries (pre-installed or separate)
• User Manuals (this document)

2. Battery Installation (if not pre-installed)

Locate the battery compartment on the back of each device. Use a screwdriver to open the compartment. Insert the specified batteries, observing the correct polarity (+/-). Securely close the battery compartment.

3. Connecting Test Leads

For the TSM-522S Multimeter, insert the red test lead into the "VΩHz" or "INPUT" jack and the black test lead into the "COM" jack. For the TCM-300D Clamp Meter, if using test leads for voltage, resistance, or continuity measurements, connect them similarly to the appropriate jacks.

Operating Instructions

General Operation

• Power On/Off: Press the power button to turn the device on or off.
• Backlight: Press the backlight button (if available) to illuminate the display in low-light conditions.
• Auto Power Off: Both devices feature an auto power-off function to conserve battery life. They will automatically shut down after a period of inactivity.
• Data Hold: Press the "HOLD" button to freeze the current reading on the display. Press again to release.

TESMEN TCM-300D Smart Digital Clamp Meter Functions

The TCM-300D offers both smart auto mode and manual selection for various measurements.

• AC/DC Current Measurement: Open the clamp jaws and enclose a single conductor. The device will display the current reading. Ensure the conductor is centered within the jaws for accuracy.
• Inrush Current Test: This function measures the initial surge of current when a device is first turned on. Select the Inrush function and clamp around the conductor of the device to be tested. The measurement range is typically 5A to 600A.

• Other Measurements: The TCM-300D can also measure AC/DC Voltage, Resistance, Continuity, Diodes, Frequency, Capacitance, and Temperature using the test leads. Refer to the on-screen prompts or the function button for mode selection.

TESMEN TSM-522S Smart Digital Multimeter Functions

The TSM-522S features a smart automatic mode that simplifies measurements by automatically detecting the type of input (voltage, resistance, continuity).

• AC/DC Voltage Measurement: Connect the test leads across the circuit or component to measure voltage. The smart mode will automatically detect AC or DC voltage.
