Fowler Xtender-E PLUS Bore Gage Set

Hi everybody it is Nick here at Higher Precision and today we are going to be doing a video demo on the Fowler Extender-E Plus Dial Bore Gage Set, part number 54-646-535.


Today we are going to be doing a video demo on the Fowler Extender-E Plus Dial Bore Gage Set, part number 54-646-535. The range of this bore gage set covers 1.4-6.0” and has a resolution of .00005” or out to one micron. The bore gage set includes all carbide tipped anvils. It is IP54 protected so it can be used in a little bit more of a harsh environment. The nice part about this electronic indicator here it has an analog scale which users can watch for a reversal point or setting up tolerancing. It is included with a nice fitted case.

Let’s take a look at the bore gage and what is included. Within it you are going to get the Sylvac electronic indicator that comes with a lifetime warranty. It includes all carbide tipped anvils to measure the full 1.4-6.0”. Now when someone takes a look at the set it does appear there are three missing anvils however the 2” anvil is already preloaded in the 2-6” foot. The small 1.4” anvil is already located in the 1.4-2” foot and the largest anvil there should not be included. In addition to the anvils you are going to get a 2” extension, as well as 4 spacers to be able to set your bore gage up no matter what size you need to measure. In addition to all the parts in there you are going to get a detailed test manual coming from Fowler on how to set the bore gage up and which anvils can be used for specific dimensions. You are going to get a LIFETIME WARRANTY card for the electronic indicator. You are going to get a detailed test manual coming from Sylvac on the indicator itself and how to use all of the functions within it. The last thing you are going in the bore gage set is a detailed test certificate coming from Sylvac on the indicator. Now I am going to take a few minutes and get this bore gage set up to be able to set it in a ring and let’s take a deeper dive into the electronics and figure out how to use this indicator and bore gage.

We now have a more detailed view on the electronic readout on the indicator. Let’s figure out how to preset this for the bore gage. Looking at the indicator you have a “minus” and “plus” button at the top. There is “mode” button, a “set” button and then in the middle here is your favorite key button (can be preset). To turn the indicator on you are going to push the “set” button once. I am going to go through the basic and advanced functions on the indicator. For the basic functions there are three of them and can get to by tapping the mode button. By tapping the mode button, you will see “select”. When you are in normal mode this will set zero. If you are in Min, Max or TIR mode, this will calibrate the indicator to the preset value. Directly after that you will have the unit which you can toggle back and forth between inch and metric. The third channel here is the “preset” which will allow you to put in a preset of the setting ring which we will do very quickly here.

In addition to the basic functions there are advanced functions as well which you can hold down the “mode” button to get to. To hold down the “mode” button, you can get to “mode”. This is where you can select min, max, tir or normal. For bore gages though you do have to have it in “min” mode. You can also set the tolerancing, you can set the resolution, the counting direction, this is automatic shutoff where you want that on or off. The last selection you have is the LOC, this is the keypad lock. If you actually want to lock out all the buttons just so people don’t get a little bit happy and hit buttons and start screwing up the measurements.

Now that we have gone through the basic and advanced functions, lets get this gage preset. The first thing we are going to do is going into the “preset” mode and put in a 1.6” dimension. I can hit the “mode” button until I see “preset”. Now one I am in the “preset”, if I tap the middle button that will take me to the next digit and by tapping the “set” button it increases the digits one at the time. So now I take my time and input 1.6” (into the electronics). The next part we have to do is to have the gage already in “min” mode. We have the preset in. We can now actually sweep this in out ring. It is going to lock on a value which we do not care what this value is until we fully calibrate the gage. So now I am going to put this bore gage in a ring and quickly sweep it. It is going to lock on to a value, but we do not care what that value is. To fully calibrate the gage, I hit the “mode” button to select and hit that middle button and that will calibrate the gage.

So it is reading 1.63890”. When I put this in the ring and sweep it again, we should be right at 1.6”. Let’s see how we did here. We are dead on at 1.6”. In between measurements, it is going to be nice and easy as you can just hit the set button (to be set up for the next measurement).

That wraps up our video demo today on the Fowler Extender-E Plus Dial Bore Gage Set. I hope you did find it helpful. If you do have any further questions you can feel free to reach out to use at Higher Precision.com and until next time, we will see you again.
