New Agilent 34405A digital multimeter 5.5 desktop reservations on the basis of cost,provide more performance.34405A with a wide range of measurement capabilities (including temperature measurement and capacitance measurements).Its dual-display characteristics can help through the standard USB interface to capturing the DC or AC measurements; and read rate can be as high as 19 readings / second,4.5 resolution.34405A also compatible SCPI language,you can easily from the existing test set for the transition.
Multimeter with voltage and current measurement
In the electronic productions,often with a multimeter in the measurement circuit voltage and current.
Will be light-emitting diodes and resistors,potentiometers,as Figure 3-4 to the circuit,rotating potential allows normal LED light-emitting diodes.LED is a special kind of diodes,learned people certain current,it will be transparent shell of luminescence.There are many color light-emitting diodes,and often do so in the light of the circuit.We will make use of this practice with a multimeter circuit voltage and current measurement.
