Choosing the Range by Hand
On a manual-ranging meter the range switch sets the full-scale value, so choose the lowest range above the expected reading: a fresh 9 V battery shows two decimal places on the 20 V range but only one on the 200 V range. With an unknown value, start on the highest setting (250 V, or 10 A for current) and step down. For current, connect the meter in series, never straight across a supply.
Transistor, Diode and Continuity Checks
The hFE position reads the DC current gain of a small transistor plugged into the hFE socket. In the diode test, a good diode conducts one way only and shows over-range when reversed. The continuity buzzer sounds at about 10 Ω or less, so a lead or fuse can be checked by ear, and data hold freezes a reading taken in an awkward spot. Switch the circuit off before any resistance, diode or continuity test.
