Each range on the DC display is used for two positions of the selector switch.
• The 10 range is used for 10V and the 1000 Volt selector switch positions
• The 50 range is used for 0.5V and the 50 Volt selector switch positions
• The 250 range is used for 2.5V and the 250 Volt selector switch positions

Some guideline to following to Protect the meter when measuring Voltage
• You do not want to “peg” the meter
–This means have the needle at full deflection
• Start measuring at highest range of the selector switch for unknown voltages
• Pay attention to circuit polarity and meter lead/probe placement
