2. Safety Information

Important Safety Precautions: Adherence to these safety guidelines is crucial to prevent electric shock, injury, or damage to the meter.

1. When measuring voltage, do not input a limit voltage that exceeds the effective value of DC 1000V or AC 750V.
2. Voltages below 36V are considered safe. When measuring voltages higher than 36V DC or 25V AC, always verify that the test leads are in reliable contact, correctly connected, and well-insulated to avoid electric shock.
3. Before changing functions or ranges, ensure the test leads are disconnected from the test point.
4. Always select the correct function and range for the measurement. Incorrect operation can lead to inaccurate readings or damage to the device.
5. Do not operate the meter if it appears damaged, or if the battery cover is not properly closed.
6. Refer to the full safety guidelines in the included printed manual for comprehensive information.

5. Setup

5.1 Battery Installation

The ET8202 requires two 1.5V AAA batteries for operation.

1. Locate the battery compartment on the back of the meter (refer to Figure 4.3).
2. Use a screwdriver to open the battery cover.
3. Insert the two AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Securely close the battery cover and fasten the screw.

5.2 Connecting Test Leads

For most measurements, test leads are required.

1. Insert the red test lead into the "VΩHz" input jack.
2. Insert the black test lead into the "COM" (common) input jack.
3. For temperature measurements, connect the thermal contact probe to the "VΩHz" and "COM" input jacks.

6. Operating Instructions

6.1 Power On/Off

To power on the meter, rotate the function dial from the "OFF" position to any desired measurement function. To power off, rotate the dial back to "OFF". The meter features an auto power-off function to conserve battery life.

6.2 Function Selection

Rotate the central function dial to select the desired measurement mode. Use the SELECT button to toggle between specific functions within a single dial position (e.g., AC/DC voltage, Diode/Continuity).

6.3 Measurement Procedures

• AC Voltage Measurement (V~):
  1. Set the function dial to V~.
  2. Connect the red and black test leads in parallel to the circuit or component under test.
  3. Read the AC voltage value on the LCD.
• DC Voltage Measurement (V-):
  1. Set the function dial to V-.
  2. Connect the red and black test leads in parallel to the circuit or component under test.
  3. Read the DC voltage value on the LCD.
• AC Current Measurement (A~):
  1. Set the function dial to A~ (600A range).
  2. Open the clamp jaw by pressing the trigger.
  3. Enclose a single conductor (not a cable with multiple conductors) within the clamp jaw.
  4. Ensure the jaw is fully closed.
  5. Read the AC current value on the LCD.
• Resistance Measurement (Ω):
  1. Set the function dial to Ω.
  2. Ensure the circuit or component is de-energized before testing.
  3. Connect the test leads across the component.
  4. Read the resistance value on the LCD.
• Capacitance Measurement (F):
  1. Set the function dial to F.
  2. Ensure the capacitor is fully discharged before testing.
  3. Connect the test leads across the capacitor terminals.
  4. Read the capacitance value on the LCD.
• Frequency Measurement (Hz):
  1. Set the function dial to Hz.
