content: In the Fluke 28 II review Dave did he noted that it has the same display that the 87v does. In particular he notes that it is a 4.5 digit display. Is this correct and Fluke's comparison site is wrong? On Flukes meter comparison site it notes a 3.5 digit display for the 28II. Can someone confirm? I am going to now see if I can find the manual online and see what it says.Melvin Stevens

content: Its got a 3.5 digit display until you hold down the button to activate 4.5 digit mode

content: From the User's Manual of 28IIDigital DMM........ 6000 counts, updates 4/sec (Model 28 II also has 19,999 counts in high-resolution mode) = slower mode.

content: I'm in the market for a new meter so I've been doing a lot of reading and internet research. I narrowed my choices down to 3 different Fluke meters: the 28II, 87V, or the 289. In my research I found several discrepancies in the data that comes from Fluke's web site. Whether they intentionally hide information for some marketing reason, or if it is just negligence/ignorance on the part of marketing, I can only guess. I eliminated the 289 from my choices because of its weight and battery life, although the specs are superb.After reading the user's manuals for the 28II and the 87V I narrowed the differences between these two meters to very few. If you do not read the user's manuals, and rely only on the specs listed on Fluke's web site, you will come to wrong conclusions. Both meters have a hi-resolution mode, although you will be hard pressed to find this spec listed for the 28II. Both meters have 3-1/2 digit displays in normal mode, and 4-1/2 digit displays in hi-res mode. Both meters have 2-level backlit displays. Both have the capability to measure pulse width. Both meters have .1 ohm resolution and .01 ohm resolution in hi-res mode. Both have 6000 count displays, 19,999 count in hi-res mode. Judging by the information on their web site, apparently, the folks at Fluke don't know this.Now for the differences between the 28II and the 87V. Here are all of them:28II has lighted keypads, 87V does not.87V uses up to 3V for diode test, the 28II only uses 2V (as pointed out by Dave).87V uses a 9V battery with a life of ~ 400 hours. The 28II uses 3 AA batteries with a life of ~ 800 hours.The 28II has an IP rating of 67. The 87V has a rating of 30.There is an obvious difference in size and weight between the two meters.And, of course, the difference in price!$

content: Yes, I think you covered it.They are essentially the same meter in terms of functionality.It just comes down to whether or not you want to trade off more size and weight for waterproof ruggedness.Dave.
