CA6250 low resistance meter @CA6250%
CA6250 uses solid shell design, is designed for plant maintenance and use of all kinds of industrial field of lowresistance measuring instrument (10A). Principle of measurement instrument using 4 line method, at present in the different manufacturers of the same specificationinstrument, is the most low resistivity instrumentprecision, accuracy is 0.05%.
The operator can through unique design of front panel button, switch quickly measuring resistive or inductivematerial resistance. CA6250 has three measurement mode: resistive (immediately), inductive (continuousmeasurement) and automatic (repeated measures) mode.Can store up to 1500 sets of measurement data, can be directly connected through the RS-232 interface serialprinter to directly print the report, or the data into PC forsubsequent processing.
Product features:
Measuring range from 0.0001m Ω (resolution 0.1 µ Ω to 2500
The test current: 1mA / 10mA / 100mA / 1A / 10A
With the RTD (thermal resistance) temperature sensor interface, can be connected with the temperature sensor(optional) measuring temperature
Alternative metal material coefficient of the analyte
Temperature compensation automatic or manual temperature
To eliminate the interference of electric potential can be measured and
Two configurable alarm set point
