4. Setup
4.1 TESMEN TOE-100BMAX GFCI Outlet Tester
- Battery Installation: The TOE-100BMAX is typically powered by internal batteries. Ensure batteries are correctly installed according to the polarity markings in the battery compartment (usually located on the back or side).
- Power On: Insert the tester into a standard 3-prong electrical outlet. The display should illuminate, indicating it is powered on and ready for use.
4.2 TESMEN TSM-522S Smart Digital Multimeter
- Battery Installation: Open the battery compartment (usually on the back) and insert the required batteries, observing correct polarity. Close the compartment securely.
- Connect Test Leads:
- Insert the black test lead into the "COM" (Common) input jack.
- Insert the red test lead into the "INPUT" jack for most voltage, resistance, continuity, capacitance, and frequency measurements.
- Power On: Press the power button to turn on the multimeter. The display will illuminate.
5. Operating Instructions
5.1 TESMEN TOE-100BMAX GFCI Outlet Tester
- Wiring Status Check:
- Plug the TOE-100BMAX into the outlet to be tested.
- Observe the display. The tester will automatically detect and display the wiring status (e.g., "CORRECT", "OPEN GROUND", "REVERSE").
- The display will also show the measured voltage (V) and potentially leakage current (mA) or trip time (ms) if applicable.
- GFCI Trip Test:
- After checking the wiring status, press the "GFCI" button on the tester.
- A functional GFCI outlet should trip (power off) within a specified time (typically 10-1000ms). The tester will indicate the trip time.
- If the GFCI does not trip, it indicates a fault, and the outlet should be serviced by a qualified electrician.
- Reset the GFCI outlet after the test.

5.2 TESMEN TSM-522S Smart Digital Multimeter
The TSM-522S operates in both auto and manual modes. In auto mode, it intelligently selects the measurement type. Use the "FUNC" button to cycle through specific functions if needed.
- Voltage Measurement (AC/DC):
- Connect the test leads as described in Section 4.2.
- Touch the red and black test probes to the points where voltage is to be measured (e.g., across a battery, across an outlet's hot and neutral slots).
- The multimeter will automatically detect AC or DC voltage and display the reading.
- Resistance Measurement:
- Ensure the circuit or component is de-energized before measuring resistance.
- Connect the test leads to the component.
- The multimeter will display the resistance in Ohms (Ω).
- Continuity Test:
- Ensure the circuit or component is de-energized.
- Connect the test leads across the points to be tested for continuity.
- A continuous beep and a low resistance reading indicate continuity. No beep or a high resistance reading indicates an open circuit.
- Non-Contact Voltage (NCV) Detection:
- Select the NCV function (if not in auto mode).
- Bring the top end of the multimeter (NCV sensing area) close to the conductor or outlet.
- The device will indicate the presence of AC voltage through audible beeps and/or visual indicators (e.g., LED lights, display segments).
- Live Wire Detection:
- Select the Live Wire function.
- Insert the red test probe into the suspected live slot of an outlet or touch it to a conductor.
- The multimeter will indicate if the wire is live.
