Affordable and Feature-Rich
Measurement Tool
The 34405A represents the latest member
in the Agilent’s DMM family and this
expands Agilent’s offerings in the
electronics measurement tools. It provides
a broad range of features and
measurement functions such as DC
voltage, DC current, true-RMS AC voltage
and AC current, 2-wire resistance,
frequency, diode test and continuity
which are designed to meet general
industrial needs. Furthermore, its built-in
thermistor sensor is able to measure
temperature ranging from -80
o
C to 150oC.
The true value is more evident with its
capability to measure capacitance ranging
from 1000pF to 10000mF. Agilent 34405A
also improves efficiency and accuracy
with its 6 built-in math operations: Null,
dBm, dB, MinMax, Limit and Hold.
Quick Connection to the PC with USB 2.0
Interface
For those with a need to control and take
preset measurements with a PC, the builtin USB 2.0 interface provides an easy and
robust connection between the PC and
DMM. The USB interface that is compliant
with the TMC-488.2 Standards, works
seamlessly with Agilent Connectivity
software and can be controlled remotely
via industry standard SCPI commands or
through DMM Intuilink Connectivity
software. IVI-COM and LabVIEW drivers
are included to ensure an easy integration
with different programming environments.
Bright Display, Fast Reading Speed and
Configuration Storage
When high throughput and productivity
are the priority, Agilent 34405A VFD dual
display feature allows users to take more
than one measurement and display them
simultaneously on the front panel. For
speed critical applications, Agilent 34405A
can take up to 19 readings/sec at 4.5
digits resolution directly to the PC. In
addition, the user can configure and store
complete instrument setups and recall
them at anytime from any of the four builtin storing states.
Rugged and Reliable
The 34405A is designed and tested
according to major Safety and Regulatory
Standards. In addition, the shock
absorbing bumpers is designed to prevent
physical damage from your day-to-day
use.
