A TRULY HISTORIC ELECTRICAL INSTRUMENT, STILL IN WORKING CONDITION.. THIS POTENTIOMETER WAS MADE TO USE WITH AN EXTERNAL GALVONOMETER AND AN EXTERNAL REFERENCE VOLTAGE SOURCE, PROBABLY A STANDARD CELL TO MEASURE VOLTAGE,CURRENT AND RESISTANCE TO AS MUCH AS 4 DIGIT ACCURACY. WE HAVE NO MANUAL FOR IT, ALL SETUP FEATURES ARE BY SWITCHES AND JUMPER STRAPS. I CANNOT TEST THIS BUT IT LOOKS COMPLETE, IN GOOD CONDITION AND USABLE THE WAY IT IS. SOLD AS- , NO RETURNS. CABINET 101
