I retired a number of years ago after spending the majority of my career working in testing and calibration labs and relocated to the northeast. I wrote calibration procedures and was the calibration procedure release focal for the largest aerospace manufacture in the U.S.A. My main area of expertise was in dimensional metrology. I also participated in writing many ASME B89 dimensional metrology standards.
I performed a “functional test” only of the amplifier.
1.) Depressing the gage head, I was able to deflect the meter moment from left to right of full scale.
2.) Using a Boeckeler 20 millionths micrometer head, I was able to perform a calibration and adjustment of the “gain” potentiometer on the amplifier on the +/-.004” range per the instruction manual.
This listing is for the following:
(1) Federal EHE-1048 gage head (with post back)
The features noted below are taken from Federal Products sales literature and may not reflect the actual performance and options of the item for sale and is provided as an overview and for informational purposes only. I will not be held responsible for its accuracy and/or content.
ELECTRONIC GAGING AMPLIFIER
Gives you your choice of magnifications without the confusion of multiple scale values. Turn the Range Selector Switch, and “Click-Scale” action (patented) makes visible the one correct set of scale values for the magnification you have selected. No chance of reading the wrong numbers or assigning the wrong values.
DUAL SPEED ELECTRICAL ZEROING…
long range approach and fine adjustment in one control for quicker, more convenient set-up. Coarse control A (outer skirt) is driven by knob B which provides independent fine adjustment when direction is reversed. This exclusive feature lets you master quickly without repositioning the gage head critically, even when height stand or fixture has no fine adjustment.
So good that Federal electronic gages can be mastered at any point on the scale. No need for a nominal size master every time.
COMPLETELY SOLID STATE OPERATION…
All Federal Multi-Choice Amplifiers are transistorized for instant use, greater dependability, cooler operation.
ADJUSTABLE AMPLIFIER POSITION…
Swivel legs provide a stable support but let you adjust amplifier position for easier viewing. They double as carrying handle.
“230” STYLE AMPLIFIERS
BUILT-IN CIRCUIT TESTER – shows overall gain of gage head- amplifier combination, not just battery voltage. Just turn Range Switch to first operating position and note whether meter hand is within “Gain OK” area. Gain readjustment is made quickly and conveniently through hole in knob.
TRULY PORTABLE – each amplifier is its own carrying case. Compartment at back houses gage head, cord, and mounting accessories. Gage Head can be used with cover in place. Battery is readily accessible by removing compartment panel.
CHOICE OF MAGNIFICATIONS – Three switch-selected scales provide popular combinations having at least 20 to 1 ratio between highest and lowest magnification to satisfy virtually every gaging requirement.
Calibration Accuracy: to within 4/5* scale division
Power: Battery Pack normally furnished.
Range of Zero Adjustment : approx. ±.005”
• Reversing spring allows measurement in either direction.
Model EHE-1048 gage head has approximately 2.5 - 4 grams gaging pressure, in either direction (knob on head reverses direction)… positive yet so light you don’t need cumbersome fixtures. Use regular test sets or height stands without the fear of lost motion.
