The DM-817 and DM-850 are two digital multimeters (DMMs) offered by Elitech, a well-known brand in the test and measurement industry. Both models share some similarities but also have distinct differences that may influence your buying decision. Here's a thorough analysis of the pros and cons of each multimeter, followed by a conclusion and recommendation.
DM-817: Pros:1. Wide measurement range: The DM-817 supports a broad range of measurements, including AC/DC voltage, resistance, capacitance, frequency, and temperature.
2. Data Hold function: This function allows users to lock the current reading on the display, making it ideal for comparing multiple readings.
3. Auto Power Off: This feature helps conserve battery life by automatically turning off the multimeter after a specified period of inactivity.
4. RoHS Compliance: The DM-817 meets the RoHS (Restriction of Hazardous Substances) directive, ensuring that it contains minimal hazardous materials.
Cons:1. Backlit display: While a backlit display can be helpful in low-light conditions, it may drain the battery faster, reducing operational time between charges.
2. Size and weight: The DM-817 is slightly larger and heavier than the DM-850, making it less portable.
DM-850: Pros:1. Compact size: The DM-850 is more compact and lightweight than the DM-817, making it easier to carry around.
2. Auto-ranging: This feature simplifies the measurement process by automatically selecting the appropriate measurement range based on the input signal.
3. Min/Max/Avg function: This function allows users to record the minimum, maximum, or average value of a signal over a specified period of time.
Cons:1. Limited measurement range: The DM-850 has a more limited measurement range compared to the DM-817, making it less suitable for more complex test applications.
2. No Data Hold function: The absence of a Data Hold function may make it more difficult to compare multiple readings.
Conclusion:Both the DM-817 and DM-850 are excellent multimeters with their unique strengths and weaknesses. The DM-817 is more feature-rich and suitable for more complex test applications due to its wide measurement range and Data Hold function. On the other hand, the DM-850 is more compact, lightweight, and easier to use, making it an ideal choice for beginners or users with simpler test requirements.
Recommendation:If you need a multimeter for more complex test applications with a wider measurement range and the ability to compare readings, the DM-817 is the better choice. However, if you're looking for a more portable and user-friendly multimeter with a more limited measurement range, the DM-850 is a great option. Ultimately, your decision should depend on your specific test requirements and personal preferences.
