Technical
features
Adoption of high-performance CPU and
programmable LSIC results in simple circuit, less adjustment , stable
perfo-mances, excellent make up ,and high rel-iability.
Standard instrument construction is
suitable for both lab and field appli-cations . in case of field use , begin
packed with a soft bag , it is small and light.
Large capacity memory for power fail-ure
is provided . it can automatically store large amount of field test data, up to
256-1024 groups(usere).
Complete computer interface functions
enable synchronous transmission of real test data , featuring intelligent
instruments and meeting international trend.
Automatical selection of input power
supply brings about conveniences in field appllcations and prevents from damages
caused by incorrect connetion of power supply.
Switch-type power supply with broad
input range of input AC voltage stren-gthens the instrument's adaptability and
lowers its power consumption.
High accuracy clamp-type current meter
can be provided.
The dot-matrix LCD Chinese prompt
available can display real-time vector chart.
The instrument can work by directly
using PT voltage.
Built-in chargeable batteries enable
operation without extemal power supplu Besidex, private data can be used to
communicate with PC and srore the data into in it.
Basic
applications
