SPECIFICATION
Electrical Specifications
(23°C ±5°C, Four-wire Measurement)
DC Voltage Measurement
Range Resolution Accuracy
0 ~ 10 V 0.001 V ± 1 % ± (1 % of Vopen ± 0.1 V)
10 ~ 60 V 0.01 V ± 1 % ± (1 % of Vopen ± 0.1 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 Resolution Accuracy
0.01 ~ 10 A 1 mA ± 1 % ± (1 % of Ishort ± 9 mA)
10 ~ 12 A 10 mA ± 1 % ± (1 % of Ishort ± 0.09A)
Ishort: short circuit current of solar cell or module.
Circuit resistance is compensated in the AUTO SCAN. Ishort is measured at
zero circuit resistance. Circuit resistance is not compensated in the Manual
Scan or Single Point Test.
DC Current Simulation
Range Resolution Accuracy
0.01 ~ 10 A 1 mA ± 1 % ± 9 mA
10 ~ 12 A 10 mA ± 1 % ± 0.09A
If current is greater than 12A, test (Auto-Scan, Scan, or Test) can not be
performed.
