- Indicator symbols for battery level, hold function, and range.
Operational Guidelines
This section outlines how to perform various measurements using the EEDM503B.
1. Measuring DC Voltage
- Set the rotary switch to the DC voltage (V⎓) position.
- Connect the red test lead to the VΩmA socket and the black lead to the COM socket.
- Touch the probes across the circuit or component terminals.
- Read the voltage on the display.
2. Measuring AC Voltage
- Set the rotary switch to the AC voltage (V~) position.
- Follow the same connection procedure as for DC voltage.
- Ensure the probes are connected to the AC circuit and read the measurement.
3. Measuring DC and AC Current
- Switch the multimeter to the appropriate current setting (A⎓ for DC, A~ for AC).
- Connect the red test lead to the 10A socket if measuring above 200mA.
- Disconnect the circuit and connect the multimeter in series with the circuit.
- Restore the circuit and read the current value.
4. Measuring Resistance
- Set the rotary switch to the resistance (Ω) position.
- Connect the leads as before.
- Touch the probes to the resistor or circuit.
- Read the resistance value on the display.
5. Diode Testing
- Switch to the diode testing mode (diode symbol).
- Connect the red lead to the anode and the black lead to the cathode of the diode.
- A reading indicates the forward voltage drop; if the multimeter displays "OL," the diode is reverse-biased or faulty.
6. Continuity Testing
- Set the multimeter to the continuity test mode (sound symbol).
- Touch the probes to the circuit or wire.
- A beep indicates continuity; no sound indicates an open circuit.
Maintenance and Care
To ensure the longevity and accuracy of your Blue Point EEDM503B, regular maintenance is essential:
1. Calibrating the Multimeter
- Periodically check accuracy against a known standard.
- Calibration can be performed by a certified technician if necessary.
2. Cleaning the Device
- Use a soft, damp cloth to clean the exterior.
- Avoid using solvents or abrasive materials.
3. Battery Replacement
- Replace the battery when the low battery indicator appears.
- Follow the battery installation instructions for replacement.
Troubleshooting Common Issues
Even the best instruments can encounter issues. Here are common problems and their solutions:
1. Display Not Turning On
- Ensure the battery is installed correctly and has charge.
- Check for physical damage to the multimeter.
2. Inaccurate Readings
- Verify the probes are connected correctly.
- Ensure the correct measurement function is selected.
- Check for a faulty test lead.
3. Overload Indication
- If the display shows "OL," the measurement exceeds the maximum range.
- Switch to a higher range or check circuit conditions.
