VOLTMETER SAFETY PRECAUTIONSJust as with ammeters, voltmeters require safety precautions to prevent injury to personnel anddamage to the voltmeter or equipment. The following is a list of the MINIMUM safety precautions forusing a voltmeter. Always connect voltmeters in parallel. Always start with the highest range of a voltmeter. Deenergize and discharge the circuit completely before connecting or disconnecting thevoltmeter. In dc voltmeters, observe the proper circuit polarity to prevent damage to the meter. Never use a dc voltmeter to measure ac voltage. Observe the general safety precautions of electrical and electronic devices.
