0 to 1V = Discharge
1V to 1.5V graduated part of scale
2V full scaleIt could have been for testing Edison "Nickel Iron" cells in Car and other batteries (Made 1903 to 1972) as they are about 1.67V on trickle charge. The open cicuit voltage is 1.4 volts, dropping to 1.2 volts during discharge.
Or possibly to test large "Igniter"/No. 6/"Flag" type Zinc Carbon 1.5V Cells (screw terminal tops) by pressing the top clips on the terminals. The "wavy" part is likely a high current drain load for cell under test. A 1.5V Zinc Carbon battery is discharged at 0.9V to 1V and is a nominal 1.4V on load, with a no load new cell as high as 1.7V
A 2V Lead Acid Cell is discharged at about 1.6V and is close to 2.3V when fully charged so seems less likely.
