Products features1. High current, adopts new power techniques, can output current
long time and continuously, overcome the malpractice of
instantaneous current of the impulse type power, can effectively
break through the oxide film of the switch contact, get accurate
test results.
2. High stability, under strong interference, the last number
displayed by the LCD within the range of ±1, with steady reading
and good reproducibility.
3. High precision: adopts double channels high-speed 16bits Σ-Δ AD
to sample, digital signal processing technique, the maximum
resolution up to 0.01μΩ.
4. Intelligent: use high performance CPU, system can switch the
measurement range according the size of the signal when testing,
ensure the accuracy. The over-temperature protection circuit can
auto stop output the current when the device exceeds the rated
temperature to ensure the safety.
5. High quality: key components adopt imported components, uses
temperature compensating circuit in perfect design which eliminates
the effect to test results by temperature, meanwhile strengthen the
resistance to shock by using the connector.
6. Powerful: current could be 50A, 100A, 150A or 200A measurement
time 5s~599s, more powerful than other equipment.
7. Friendly man-machine interface: enter the data by rotating
mouse, easy and convenient, can set the data, time by yourself,
save and print the test results in time.
8. USB dump: Store the data to U disk by USB interface, combining
PC software for further analysis and processing of the measurement
data.
9. Easy to use: small in volume, light in weight.
