® ® Analog bar-graph AutoHold Real-Read The analog bar graph provides a visual indication of measurement Accuracy: Specified accuracy ± 50 digits like a traditional analog meter needle. It is excellent in detecting Availability: Resistance, Continuity, LoZ AutoV, VFD Volts, faulty contacts, identifying potentiometer clicks, and indicating Voltage and Current functions signal spikes during adjustments. - Page 12 ® ® Note: 1)Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent hard signals, which confuse common multimeter voltage measurements. The AutoV mode provides low (ramp-up) input impedance (approx. 2.1kΩ at low voltage) to drain ghost voltages leaving mainly hard signal values on meter readings.
