CR-20V2000m ohm battery voltage internal resistance tester
Equipment type: CR-20V2000m ohm, battery testing equipment, material coding: CR-20V2000m
Index item index parameter
Measurement method four terminal test method
Voltage and voltage measurement range 0V~20V
Accuracy is equal to (0.1% of FS + 0.1% of reading)
Resistance and resistance measurement range 200m ohm \2000m ohm two kinds of automatic switching
Accuracy 0m Omega ~200m + (0.5% of FS + 0.2% of reading)
200m Omega ~2000m + (0.5% of FS + 0.2% of reading)
A/D mode 12 bit SAR successive comparison method
Frequency test frequency 1kHz
The sampling rate was 100 times /S
Display refresh rate 5 times /S
Test current MAX AC 20mA
When the comparator abnormal alarm mode uses the comparator, the ON/OFF setting of the buzzer can be carried out
When the voltage or AC internal resistance exceeds the upper and lower limits of the comparator, the buzzer rings
The green indicator light is qualified, and the red indicator light is unqualified
Number 10 groups of voltage and internal resistance upper and lower limit
Turn on / off manually
Storage functions can store up to 100 thousand sets of test data
View the function to view the history test results
Calibration function zero calibration, simultaneous calibration of voltage and internal resistance zero
Voltage calibration uses external DC 3V to 20V (set) benchmark calibration voltage
AC internal resistance calibration uses 10~2000m ohm (can be set) precision resistance to calibrate internal resistance
External control terminals extend scalable automated testing, scalable USB communications (optional accessories, not included in the standard)
Preheating time is over 3min
