GW Instek GDM-8245 Pros/Cons and My Thought

The GW Instek GDM-8245 is a 50,000 counts digital multimeter (DMM) with a variety of features, including True RMS AC/DC voltage and current measurement, resistance, capacitance, frequency, duty cycle, diode test, continuity, and more. It also has a dual display that can show either ACV and Hz, or DCV and dBm.

Pros:

• Large, easy-to-read LED display
• True RMS measurement for accurate readings of AC signals
• Wide range of measurement functions
• Dual display for convenient viewing of multiple measurements
• Built-in memory for storing and recalling measurements
• Auto power-off to save battery life

User reviews:

• Positive: "I love the large LED display on this DMM. It's so easy to read, even in bright sunlight. The True RMS measurement is also very accurate. I've used it to troubleshoot a few electrical problems in my home, and it's been a lifesaver." - FriendlyWire
• Negative: "I wish this DMM had a backlit display. It can be difficult to read the measurements in low-light conditions. I also wish it had a USB port for data transfer. I would like to be able to save my measurements to a computer." - Coromonadalix

My thoughts:

Overall, the GW Instek GDM-8245 is a great DMM for the price. It has a lot of features and is very accurate. The large LED display is easy to read, and the dual display is a nice touch. The only real downside is the lack of a backlit display and a USB port. However, if you can live with those two things, then the GDM-8245 is a great choice.

Here are some additional thoughts on the GDM-8245:

• The True RMS measurement is very important for accurate AC voltage and current readings. Most cheaper DMMs only measure AC voltage and current in the peak-to-peak mode, which can lead to inaccurate readings.
• The dual display is a great feature for viewing multiple measurements at the same time. This can be helpful for troubleshooting electrical problems.
• The built-in memory is also a nice feature. This allows you to store and recall measurements for later analysis.
• The auto power-off feature is a great way to save battery life. The DMM will automatically turn off after a certain period of inactivity.
• The durable construction is another plus. The GDM-8245 is built to last and can withstand the rigors of everyday use.

Overall, I think the GW Instek GDM-8245 is a great DMM for the price. It has a lot of features, is very accurate, and is built to last. If you're looking for a new DMM, I would definitely recommend checking it out.
