Siglent Technologies SDM3045X 4-1/2 Digit Digital Multimeter, DMM

For the price you cant beat this product, it looks great, is sturdy and measures with great accuracy, obviously for more precision your going to have to fork out some more money but if your doing that kind of work you probably aren't looking into this product or at least I hope your not, as you probably have a bad understanding of the necessary electronics to handle great precision and big ranges, at the same time, things like that don't come cheap.The LCD screen is great and has an easy to use menu and allows viewing measurements over a period of time rather than just the current value. I do wish it was LAN capable but I also understand that Siglent have to make money somehow and entice you into buying their higher end products so I'm not mad it would just be nice to have.The certificate of calibration is great because you know its measuring correctly and up to standards right out of the box and can be recalibrated in the future, if its off just recalibrate unlike some really cheap electronics that when not measuring correctly are just broken and useless.

I have run this meter through the paces for over a month now, and I continue to enjoy the huge array of features it has for the price. I use the trend graphing, voltage, and 2&4 resistance measurements the most. I have noticed no quirks or issues yet, and I believe it will hold up. As a hobbyist, I just could not justify spending $900 for a similar competing model, when this one has the basic accuracy and functions I need. I will be keeping this one in the center of my bench for a number of years.

This 4-1/2 digit digital multimeter has a lot of functionality for the price. Also, it is very easy to use. The instructions and documentation for this device is very straight-forward and easy to follow. It also has the capability to be used with automated test procedures in several programming languages. Siglent also has a computer application called, EasyDMM that can be used to control and monitor this device via a computer. Don't let the price fool you. The quality and materials of this device is of very high quality.

I recently purchased a new O'scope. I finally decided on a Siglent. Differing views on quality made it a bit of a decision. But, the unit was actually better than expected and side by side with on old Rigol of similar specs, it was easier to use and seems to have all the features I need.So, I decided to add a new DMM and chose another Siglent. Based on the o'scope I figured it would be a safe choice and I did less research. Came on time, looked good on the bench. Plugged it in, hit the on button and the Siglent logo came up just like the O'scope. But, like a deadbeat relative or a stray cat, the logo never left. It just stared at me until the screen saver kicked in and let me look at a black screen instead of the logo.Research quickly indicated that others have that issue. Firmware update was not possible--could not get to the screen to do that. Not wanting to send a brand new unit back to Siglent as they wanted, I sent it back to Amazon.Might be a good machine, but there seems to be a known issue relating to the boot failure. My old GW/Instek is gonna have to hang in there for a little while until I decide what I really want. With a 50/50 good/bad on Siglent, I am going to tread carefully if I go that direction.

This is a Nice and easy-to-use Meter but it really needs to have better leads.The stock leads are not gold plated and even after cleaning the leads theystill had additional resistance in the leads leading to erroneous measurements.I purchased a set of Probe Master test leads and the meter now performs properly.The Probe Master leads are gold-plated (the gold-plating makes a difference here).Note: This Meter did come in with a Current Calibration Certificate.

**update** Siglent replied with a link to the SW update. Put it in a flash drive, updated, and now works like a champ. Would buy again!Worked great, flawless I would say for over a year. Then, after being unplugged for 6 months, it would not boot. This may be corrupted firmware or something but I’m waiting for Siglent’s reply on the path forward.

I’ve been using DVM’s for more than 50 years. I have worked In commercial labs and test systems. I have used some of the highest and an accurate equipment made. It is nice to see a reasonably priced laboratory grade DVM in this price range. I only wish that it would power on and boot up faster than it does.

About 1.5 years out of cal, actually. Really should send it back, but is for my home shop and is close enough for my needs.Other than that I love the thing. It does everything possible in a multimeter in this price range.No other company has a display this crisp and readable. The 2nd display is now larger than manyreviewers have claimed. (fixed in a firmware update).Nothing wrong with the included leads, but you will want additional leads and adapters - take myadvice and find leads with in-line connectors instead of right angles. They'll fit easier.One other niggle I see: Amazon claims this comes from the Siglent Storefront, but Siglent website fails to list Amazon as a qualified seller. I'm sure the warranty is fine, but hope never to haveto find out. I saved a few bucks...
