The amperage rating is printed on the unit. On some meters both are fused. You could also just check how high the dial goesdo not attempt to test more currents than the highest dial setting.
A multimeter configured to measure current on the high amperage setting red probe in the A socket rotary dial turned to the A setting Note that whether either of the two amperage sockets have an internal fuse varies meter to meter.
Turn the central dial of the multimeter to the amperage. When the leads are separated the reading should be 1. Setting a digital multimeter range. Next turn the wheel to a higher amperage than whats expected.
