Measurement methods

Four terminal test method

Voltage

Voltage measurement range

0V~20V

Precision

± (0.1% of FS + 0.1% of reading)

resistance

Resistance measurement range

200mΩ2000mΩ two kinds can be automatically switched

Precision

0mΩ ~200mΩ ± (0.5% of FS + 0.2% of reading)

200mΩ~2000mΩ ± (0.5% of FS + 0.2% of reading)

A/D method

12-bit SAR successive comparison method

frequency

Test frequency

1kHz

Sampling Rate

100 times/S

Display refresh rate

5 times/S

Test current

MAX AC 20mA

Comparators

Open method

Manually open/close

Quantity

10 sets of voltage and internal resistance upper and lower limits

Abnormal alarm method

When using the comparator, the buzzer can be set to ON/OFF

When voltage or AC internal resistance exceeds the upper and lower limits of the comparator, the buzzer will sound

Green indicator light means qualified, red indicator light means unqualified

Storage function

Can store up to 100,000 sets of test data

View function

Can view historical test results

Calibration function

Zero point calibration

Calibrate the zero point of voltage and internal resistance at the same time

Voltage calibration

Use external DC 3V～20V (settable) reference calibration voltage

AC internal resistance calibration

Use 10~2000mΩ (settable) precision resistance to calibrate internal resistance

External control terminal expansion

Extensible automated testing, expandable USB communication (optional accessories, not included in the standard configuration)

Preheat time

More than 3min
