THIS FIRST LOT IS FOR 12 PRE-WWII METERS. THESE METER AND A FEW OTHER STARED THE SERIES PRODUCED FOR OVER 77 YEARS. I'M BUILDING THIS LISTING IN PIECES AS I HAVE TIME. I WILL LIST THE FOLLOWING: THESE 12 METERS ARE MODELS 230(B) BLACK, 235 (R) RED, 235 (B), 240 (R), 245 (R), 280 (R), 282 (R), 282 (B), 284 (R), 284 (B), 285 (B) AND 286 (R).

EACH METER IS NUMBERED IN HE PHOTOS. PAY NO ATTENTION TO THE A & B ON THE WHITE LABELS. 1 A BRIEF HISTORY OF THE MICRO METERS FROM THE LATE 1930S UP TO THE LAST METERS CATALOGED, THAT I KNOW OD, IN THE YEAR 2000. THE SIMPSON METER COMPANY WAS WELL KNOWN FOR THEIR EXCELLENT LINE OF MULTI METERS IN THE LATE 1930s. BY 1940 SIMPSON HAD INTRODUCED THEIR NEW MOCRO METER LINE.

THESE SMALL MICRO METERS WERE DESIGNED TO MEASURE ONLY ONE FUNCTION. By 1940, Simpson had introduce the following 7 meters. 281 AC Voltmeter 0-150, 300, 600 volts. 282 DC Ohm-meter 0-1000, 10K 100K 1M 10M Ohms. 283 DC MA 0-1, 5, 10, 25, 50, 100, 250, 500, 1000 MA.

284 DC UA 0-50, 100, 250, 500, 1000 UA. 0-1, 2.5, 5, 10, 25 Amps. 286 AC Volts 0-5, 10, 25, 100, 250, 500, 1000 Volts AC. 287 DC Volts 0-4, 2.5, 5, 10, 25, 50, 100, 250, 500, 1000 Volts DC.

There may be other meters, but this is all I discovered. IN ADDITION TO ABOVE, THE FOLLOWING METER WERE ALSO PRODUCED PRIOR TO WWII. 205 VOM DC VOLT AND CURRENT, RESISTANCE 10 FUNCTION?

230 VOM with 12 functions. 245 DC Volts and Battery tester, 0-2, to 150 Volts with or with out load. 280 AC Amps 0-1, 2.5, 5, 10, 25 Amps. THERE WAS A TOTAL OF 13 METERS DIFFERENT METERS PRODUCTED PRIOR TO WWII, that I know of.

Let me know if you know of more. All PRE WWII these meters measure 2.93 W, 5.33 H, 1.78 H, average weight 19 Oz. Colors were either Black or Red.

Not sure if all were produced in both colors. 3 I WILL DESCRIBE THE DETAIL CONDITION OF EACH METER I LIST. THESES METER CASES ARE FRAGILE AND EASILY CHIP OR CRACK. PLASTIC WAS SOMETHING NEW BACK IN THE LATE 1930s. 4 I WILL TEST EACH METER AS BEST I CAN.

WILL LIST MY FINDINGS AS TO METER FUNCTION. I DON'T PLANE TO DO MORE THAN A METER FUNCTION, I'M NOT GOING TO TRY TO CALIBRATE THE METERS.
