Vintage Simpson 262 series 3 20,000 OHMS DC 5000 OHMS AC. VAC VDC

The Vintage Simpson 262 series 3 meter. It works but I have no idea if its accurate. When OHMS test a new D battery the needle moved to the right on zero. Im not an electrician, but when I tested a new D battery it read 144 or 1.44v. When I tested with my digital multimeter it read 1.62 v. I dont know if can be adjusted or not so im selling it “as is” . It comes with original box and Manuel. Last picture is a test of new D battery.
