This is a resistance bridge type tester for resistance from 0.1 ohm to 1000 ohms.
The label on the unit translates to Yokogawa Electric Works Co., Ltd., Japan. The year of manufacture is Showa 19 or 1944. The month is March.
It uses a hand-cranked generator to power a bridge circuit. The indicator is a small meter, and a potentiometer is used to center the meter while the crank is rotated. The resistance is read from a scale on the potentiometer.
