Page 10: 5-5.Backlight/Hold Button
True RMS Multimeter User Manual • Momentarily press the MAX/MIN/AVG button to view the lowest reading. The “MIN” indicator will appear on the LCD display. The meter will display and hold the minimum reading and will update when a lower “min” occurs. •... -
Page 11: 5-7.Ac/Dc Voltage Measurememts
True RMS Multimeter User Manual • Press the PEAK button for approximately one second to switch between Peak MAX and Peak MIN readings. • Press and hold the PEAK button to exit PEAK and return to normal operation. NOTE: The meter does not Autorange when the Peak mode is active. The display will read OL if the range is exceeded. -
Page 12: 5-9.Low Z Voltage
True RMS Multimeter User Manual 5-9.Low Z Voltage WARNING: Observe all safety precautions when working on live voltages. Do not connect to circuits that exceed 600V AC/DC when the meter is set to Low Z. Low Z is used when there is a suspicion of a “ghost” voltage. Ghost voltages are present when non-powered wires are in close proximity to wires powered by AC voltage. -
