 Power Output: 
 Output energy range OUTPUT --- .0.2-2.0 kA (KA). 
 Supply voltage stability: 
 Accuracy of current screen display 0.05KA, resolution time display accuracy 0.01S. 
 Cut off the voltage reading exceeds the value of the charging circuit requires a resistor connected to the capacitors at both ends, the capacitor discharge to the required voltage level. Insensitive zone volume control circuit for the maximum voltage of about 0.6%. 
 Line fault step-down: 
 This is a safety feature, when the input power suddenly cut off, an automatic step-down resistor connected, the capacitor discharge. 
 Ignition circuit: 
 Require an external ignition closed accounts or low-touch control logic circuit. Internal filtering device to prevent electrical interference (RFI) caused by the ignition off. 
 Over-current protection: 
 When the system fails, the device automatically shut down to avoid equipment damage.
