4.2. MEASUREMENT DESCRIPTION
4.2.1. DC Voltage measurement
WARNING
Maximum input for DC voltage is 500V . Do not attempt to take any
voltage measurement that exceeds the limits. Exceeding the limits could
cause electrical shock and damage the multimeter.
1. Select a proper range for DC voltage (2.5, 25, 250 or 500 DC V).
2. If the voltage range is not known beforehand, set the range switch to the highest range
and work down.
3. Insert the two long ends of test leads to the desired circuit, then reading will be
displayed in the corresponding black scale.
