The HD110B and HD115B Heavy Duty Digital Multimeters are 3-1/2 digit, manual ranging, AC-coupled average measuring RMS reading display instruments that measure: voltage, current, resistance, continuity, and diode junctions. The HD115B also measures capacitance. Menu selection allows Data Hold and AC or DC voltage and current selection. The HD115B has additional menu buttons for Probe HoldTM, Peak Hold, Maximum/Minimum and the Backlight. Both meters have a Safety TesterTM to indicate voltages present even if the meter’s battery is dead.
