Disassemble the PDP-8 program

This is a PDP-8 program. Please, anyone can take it apart.

Binary representation   Octal Representation
111000000001            7001
010000011100            2034
101000010001            5021
101000010000            5020

I want to know what this code does.

PS: This is not homework. I just found this code in the video. There is no explanation for this.

7001         IAC      Increment the accumulator 
2034         ISZ 24 Increment location 0024, skip next instruction if zero 
5021         JMP .-1  Jump back one place 
5020         JMP .-3  Jump back to beginning

The source , about half the page, is an accurate program.

This whole program adds one to the battery, then it calculates from 0 to 4096, then adds another one to the battery and so on ... adding up to 4096 is a sufficient delay so that higher-order batteries can be turned on and off, and not just flicker fast.
