Fluke BT521 Battery Testing Device

I cant download the sequence profile. Can you help me?

I bought this battery analyers for work, and this product has saved me alot of lost time troubleshooting

The latest firmware is awesome !!!, including strap test, according to IEEE 1188 standard.

The BT521 could measure the negative pole temperature but could not be displayed on the unit itself. The only way to review the temp data is to download the data to the PC. This temp data should be able to review on the unit itself during the site testing. All current test probes are straight only. If Fluke could provide the angled tip, it would be best for tight environment since the workable space on top of the battery bank are quite limited in most of the environment. All accessories are not upgradable, i.e. BT510 could not be upgraded to BT520, and BT520 could not be upgraded to BT521. However the time of purchasing this sort of instrument may not have adequate budget to purchase the top of the series model. If it is upgradable, it will be fine for the starter since most of the accessories could be an optional item. I'm not sure whether this BT5xx will be compatible with the Fluke Connect in the future. The BT521 is already equipped with Bluetooth connectivity to iOS devices. I hope it will be supported by Fluke Connect in coming soon such that my Fluke Connect ready equipment could be managed together under a single platform.

The BT521 is a high end battery tester. The Probes are interesting: the short pair of the advanced probes came broken, Fluke is warrantying them out. (But still....). The probes require calibration EACH TIME you switch a set. And calibration is challenging, to say the least. You need two people. And it takes time. And repeated attempts. The software: you CANNOT create templates without being connected to the instrument. ?!?! And I'm not sure what the Fluke Connect App really lets you do. It didn't seem to do anything. All in all: well made, intuitive to use, easy to use (except the calibration proceedure), and the data logging is a great way to capture readings. But it has a 'personality,' as mentioned above, that you need to get used to. But, I have to say, the same is true of my 190-504, my 435-ii, and my 1625-2. It seems as though as the instrument capability goes up, so does its price and quirks. That being said, I'd still rather own Fluke that anything else. If for no other reasons than Fluke's reliability, customer service, and the confidence it inspires in my clients, I'll keep them as my primary test tool.

I went with the Fluke bt521 for the reason of price and safety over other battery testers. I use this tester every 3 months when I test our 1200 batteries of our site.My biggest frustration with this tester is the probes, they are tethered together at the end of the probe. This gets to be very cumbersome when trying to reach into the back corner of a battery rack. Also only having straight probes does not work well in a lot of situations, they need to have angled probes for hard to get to areas. The temperature meter on the end of the negative probe is cool, but it gets in the way a lot, again when reaching into hard to get to areas.
