Battery Cell Tester (0327)
Info
Voltage/Amperemeter for testing battery cells. The dial has a voltage range from -2 to 2 Volt. The lower Amperes scale ranges from -150 to 150 A. The meter would be used by pressing the 2 pins onto the battery poles, as such applying a load to the battery by means of the resistor coil. By removing the coil, no-load voltage can be tested.
The casing looks like an early plastic. Doesn't seem bakelite at first glance.
The handle is some kind of hardwood.
There are no indications of maker or type.
