This new generation of micro-ohmmeters
offers flexibility of measurement with high accuracy and exceptional
functionality. The DO5000 encompasses all the features required
of an ohmmeter in one instrument. Programmable measuring current
in 100 steps ensures that the DO5000 is suitable for all your
applications. Automatic temperature compensation references the
measurement to 20°C and Hi/Lo limits permits sorting of components
with the minimum of fuss. All these options are included in the
basic unit as well as a data logging function which stores up
to 4000 readings with date and time stamp. Statistical analysis
of these values allows you to display the Max/Min/Average values
as well as peak to peak and standard deviation. The DO5000 is
a truly remarkable instrument and ideally suited for laboratory
testing of samples, for production line testing, and with the
addition of the interfaces RS232/IEEE-4888 or PLC the DO5000 may
be remotely controlled and integrated into an automated testing
system. For those applications where speed is important, the DO5000
has a FAST measurement mode which measures at 50 measurements
per second.
DO-5001 Battery Version
The DO5000 is also available with rechargeable batteries; the
batteries are housed internally together with the intelligent
charger circuit. The batteries used are sealed lead acid type
and the built in charger maintains them in optimum condition.
The performance and functionality of the DO5001 is the same as
standard mains only version. When measuring on battery power,
the DO5001 automatically switches to single measurement mode to
preserve battery life and maximize the operating time. The DO5001
will both charge the batteries and provide full 10 Amps measuring
current when connected to mains supply. For real portability combined
with measurement accuracy, the DO5001 is the best choice
DO-5002 Low CurrentVersion
With all the functionality of standard DO5000 but with limited
measuring current and the ability to limit the open circuit voltage
to either 20mV or 50mV. This model has been primarily developed
to satisfy those applications where open circuit voltage and the
measuring current needs to be limited. A typical application is
for the measurement of switch contact resistance to conform to
standards such as NFC93050.
