MEASURING AC CURRENT WARNING • Beware of electrocution. • Ensure that the test leads are disconnected from the meter before making current clamp measurements. • Set the rotary selector to the 40A or 400A range position. • Push the “REL” key to make sure that the LCD displays zero. •... -
Page 12: Measuring Ac Voltage
MEASURING AC VOLTAGE WARNING • Beware of electrocution. • Pay special attention to avoid electric shock when measuring high voltage. • Do not input voltage, which is more than 750V rms AC. • Plug the black test lead into the COM jack and the red test lead into the INPUT jack. -
