. Adopt 20*2 character LCD display, display parameters are eye-catching and intuitive.
2. Constant current output: the stability rate of output current should be within 1% to avoid the instability of input power supply voltage
The output voltage changes with the change of load, and the measurement result is not accurate.
3, with open circuit alarm function.
4. Adopt four-terminal measurement method to eliminate the influence of contact resistance.
5. Optional output frequency: 50Hz/60Hz.
6. Resistance offset can be set.
7. It has the alarm function of upper and lower limit of resistance to avoid misjudgment of the time part under test due to the open circuit of the test line;
8. With 20 memory groups, 20 different parameters can be saved.
9. Setting parameters have the function of power off memory.
10. Test parameters have maintenance function.
11. The maximum test time is 999.9s
12. A foot switch is attached
Main parameters:
Current setting: 3.0a ~ 30.0a
Resolution: 0.1a accuracy: (1% set value + 0.1a)
Output frequency 50Hz/60Hz is optional
Resolution: 1 m Rset=(30A/Iset) x 150m
Ammeter 3.0 ~ 30.0A resolution: 0.1a accuracy: (2% set value + 0.2a)
Resolution: 1 m accuracy: (2%+2 m)
Test time setting 1-999.9s 0=Continue resolution: 0.1s accuracy: 5%
The environment temperature 0 to 40 ℃; Relative temperature: no more than 75%
