Features he HP34401A is setup for bench-top use with AC power supply. It performs at 1000 readings/sec and has a 6½-digit display. The HP34401A will automatically adjust the range to the characteristic being measured. It is also extremely accurate: 0.0015% error for DC, 0.06% for AC.
Breadboard and circuit components (if needed) 2. Turn on the Multimeter. The front panel display will light up while the meter performs the power-on self –test. After this is complete, the HP34401A is ready to perform measurements. Overview of Controls Probe Input Panel...
T A K I N G M E A S U R E M E N T S Section How to Measure DC and AC Voltage To measure a voltage, connect the probes to the HI and LO input terminals of the DMM. In order to activate the DMM for voltage measurements, select either the AC V or DC V button on the front panel (Figure 2).
T A K I N G M E A S U R E M E N T S How to Measure DC and AC Current To use the DMM as an ammeter, connect the leads in which the current flows to the current (I) and LO terminals (Figure 4).
T A K I N G M E A S U R E M E N T S How to Measure Resistance To use the DMM for resistance measurements, connect the resistor to the terminals labeled HI and LO, select the resistance measurement function by pushing the [ ] button on the front panel as shown below in Figure 6.
