Description: NO OVERSEAS/INTERNATIONAL BIDS!!!! Sale is intended for the U.S.A only. NOTE: Please contact me for a shipping rate quote if you live in Alaska or Hawaii. 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 a Federal EHE-1xxx series gage head*, I was able to deflect the meter moment from left to right of full scale. (See photos).NOTE: There was an anomaly when I attempted to perform a calibration in that at the far right of the scale the amplifier will deviate more than 1 division from nominal. As an example, I could obtain accurate readings (well within mfrs. spec of 4/5 of division) at -.010”, -.005”, 0 and at +.005”. However, when measuring at +.009” the display would read +.010” (or 2 divisions, that is each division being .0005"). If you split the error of 2 divisions (by adjusting the calibration/gain potentiometer) and compensate the readings at -.010”, -.005”, 0, and +.005” you may obtain an error of less than 1 to 1-1/2 divisions.*NOTE: Does not include any EHE-1xxx series gage heads. NOTE: There are some cosmetic imperfections (see photos). Due to its age, and the nature of vintage test equipment it is being sold “AS-IS”. All SALES ARE FINAL. NO RETURNS.This listing is for the following:(1) Federal EAS-1233 electronic gaging amplifier NOTE: The 5.4V mercury cell battery pack which was normally furnished when this item was originally made has been replaced with a battery holder and (4) new Duracell “C” cell batteries. NOTE: In 1996, the United States Congress passed the “Mercury-Containing and Rechargeable Battery Management Act” that prohibited further sale of mercury-containing batteries unless manufacturers provided a reclamation facility, effectively banning their sale. NOTE: I have an optional Federal EAT-1002 battery eliminator for sale in a separate auction. 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 AMPLIFIERFEATURES:“CLICK-SCALE” PRESENTATION…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. LINEAR RESPONSE…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 AMPLIFIERSBUILT-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. SPECIFICATIONS:Analog Models Model RANGE MINIMUM GRADUATION MAGNIFICATION EAS-1233 ±.010” .0005” 220X ±.002” .0001” 1100X ±.0004” .00002” 55000X The “gaging amplifier” will only be shipped by USPS priority mail within the U.S.A. I will not ship to post office boxes, unconfirmed addresses or third parties. I reserve the right to close the auction early in order to permit a local sale.
