The Surge function allows users to set Surge current, Normal current, Surge Time and Surge STEP according to test requirements.

Surge Time can be set from 10 to 1000ms, and Surge STEP can be set from 1 to 5.

Surge and normal current ranges for surge testing are model dependent:

• PEL-503-80-50
• 0-50A
• PEL-504-80-70
• 0-70A
• PEL-504-500-15
• 0-15A
• PEL-507-80-140
• 0-140A
• PEL-507-500-30
• 0-30A

The battery discharge test function can determine the conditions to stop the discharge according to the test requirements of the DUT, including setting the stop discharge voltage (Vbatt), discharge capacity (AH, WH) and stop discharge time.

The GO/NG function is applied to monitor the test result. When the test result exceeds the preset upper/lower limit, the front panel display screen will display NG. Otherwise, GO is displayed. The GO/NG function can edit the working procedures of the test in CC mode/CR mode/CV mode/CP mode. After the test procedures are executed, the test result will be displayed on the front panel display screen, which is represented by GO or NG.

With the operating mode of constant current, the PEL-500 series electronic load will sink a current in accordance with the programmed value regardless of the input voltage.
