• Exercise extreme caution when: measuring voltage >20 V
// current >10 mA // AC power line with inductive loads //
AC power line during electrical storms // current, when the
fuse blows in a circuit with open circuit voltage >600 V //
servicing CRT equipment.
• Always measure current in series with the load – NEVER
ACROSS a voltage source. Check fuse first. Never replace a
fuse with one of a different rating.
• Remove test leads before opening the case.
