Electrical Specifications (23°C ±5°C, Four-wire Measurement)
DC Voltage Measurement
Range (60V / 6A) Resolution Accuracy
0 ~ 6 V 0.001 V ± 1 % ± (1 % of Vopen ± 9 mV)
6 ~ 10 V 0.001 V ± 1 % ± (1 % of Vopen ± 0.09 V)
10 ~ 60 V 0.01 V ± 1 % ± (1 % of Vopen ± 0.09 V)
Vopen: open circuit voltage of solar cell or module.
If users use alligator clips to measure voltage only (I+ clip is not connected),
clips (V- and I-) must be shorted together. Thus, 4-wire measurement is
converted to 2-wire measurement.
DC Current Measurement
Range (60V / 6A) Resolution Accuracy
0 ~ 0.6 A 0.1 mA ± 1 % ± (1 % of Ishort ± 0.9 mA)
0.6 ~ 1 A 0.1 mA ± 1 % ± (1 % of Ishort ± 9 mA)
1 ~ 6 A 1 mA ± 1 % ± (1 % of Ishort ± 9 mA)
Ishort: short circuit current of solar cell or module.
Internal Resistance at Ishort: 0.05 Ohm.
Ishort is measured with internal resistance, circuit resistance, and test lead
resistance.
DC Current Simulation
Range (60V / 6A) Resolution Accuracy
0 ~ 1 A 0.1 mA ± 1 % ± 0.9 mA
1 ~ 6 A 1 mA ± 1 % ± 9 mA
If Current is greater than 6A, test (Auto-Scan, Scan, or Test) can not be
Performed.
Maximum duration of simulation is 9.999 seconds if power is less than 100 W.
Duration of simulation is 10m seconds if power is greater than 100 W.
