The display module features three types of meters. The analog meter is for "peaking-up" an experimental signal. The digital voltmeter provides a numeric readout. The "Digital Hold" button may be used to hold the digital meter’s reading. A 20-segment bar graph display may be used to show rapidly changing data.
