Often, and even with the best of intentions, bias on the part of the observer(s) is a factor in the results!

 

MY digital meters are VERY easy to "read" (and process) at a glance. Maybe I have been conditioned to them over the fourteen-years (since 1998) I have owned my two Z-4000's!

Aren't there also studies which always produce the same results?

Gentlemen:

 

My LIFE depends on hemodialysis modality protocols.

 

For example, one study produces an acceptable  range for the Pth (parathyroid hormone) of 150-300, while another a range of 150-600!

 

Th kicker is the Tennessee protocol is the first one, while my North Carolina unit uses the latter. Go figure.

 

BTW, the Pth hormone regulates serum calcium and phosphorus, which in turn, affects the bone structure in end stage renal disease (kidney failure), which can result in osteopenia or worse, osteoporous!

 

And the medication (Zemplar) level depends on the Pth level.

 

How does one reconcile two DIFFERENT conclusions from studies about the SAME subject?

 

Different data collection, observation methods, and many other variables? Or just FLAWED (biased?) studies similar to cancer research re: what causes cancer: resulting in a different "flavor of the month"!

 

Some studies do confirm one other, but many more conflict with one another.

 

A healthy dose of skepticism is in order!

You're correct, cjack. Bear in mind that Tinplate Art is a contrarian from way back. 

In fact, the superiority of analog instruments in transmitting information to the human brain has been settled now for so long, without contradiction, that it's pretty much set in stone. I did a little work with a psychologist who worked at NASA 40 plus years ago on ergonomic cockpit design, and it was well-settled a good deal prior to that time.

Gentlemen:

 

There are ALWAYS exceptions when it comes to human behavior.

 

I have been monitoring those digital meters on my Z-4000 for FOURTEEN-YEARS, and have made rapid adjustments to the voltage level whenever necessary without hesitation. Maybe I have a digital gene?

 

Seriously, I believe the new Lionel ZW-L will be a huge success, and it is a handsome design in spite of the analog meters!

 

Contrarian? Really?

Here's the guy with the meters, same vendor had the voltmeters: C:US:1123" target="_blank">AC 0-10A Analog Panel Ammeter

During the digital "craze" when the car manufacturers were going digital on the dashboard I felt that digital was a step backwards. Same for clocks. Reading digital gauges requires an extra line of code in the brain. It may be different for babies that grew up with digital.

Being a User Experience designer who does a lot of Usability testing, i would disagree. The scan time for a analog gauge is longer than a digital gauge.

Sadly, a lot of these organizations feel its their JOB to find something wrong with products... then "force" the designer to make appropriate adjustments so they could justify being involved in the process.  Giving products a blanket stamp of approval too often would give the appearance they're not justifying their worth to the process.  Frustrating, I'm sure. 

 

For the heck of it, I just checked our hairdrier rating, and sure enough... a whopping 1875 watts!    And it's UL listed, but I guess Conair gets the approval 'cause they're not marketing directly to "kids".  But I can only imagine the number of households where young kids use hairdriers everyday.    Silly that Lionel was required to reduce the new ZW's power output for the reason they stated.

 

 

More deaths have occurred from hairdryers than from toy train transformers, I can assure you that.

You're free to believe what you like.  I can point to a mission-critical application, the aircraft cockpit.  The reason they're still presenting analog representations in a glass cockpit is that a lot of pretty smart folks don't believe you.  There have also been extensive studies on the topic for aircraft cockpits, and the answers always come up the same.

Just for information. In reference to Analog Panel Ammeter. I was reading yesterday a members remarks about AllElectronics.com. I checked out their site and ordered the 0-15 amp and the 0-25 volt meters. The cost is more than the e-bay site, $12.00 each and $7.00 shipping. The good news is the order is shipped already from CA.

I had ordered 2 each from the e-bay site about 10 days ago and there still in China. I'm guessing meters are the same, but we will see. I needed them like yesterday.
