Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials. The two major applications of eddy current testing are surface inspection and tubing inspections. Surface inspection is used extensively in the aerospace industry, but also in the petrochemical industry. The technique is very sensitive and can detect tight cracks. Surface inspection can be performed both on ferromagnetic and non-ferromagnetic materials

Function Introduction
Charge
Active, pre-charge, constant current and constant voltages are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries. For charging mode and current, please refer to the paragraphs of charging mode and charging current on page 2 & 3.
Tester will stop charging if one of the conditions below was met.
1) Remaining capacity 99% & current intensity = 0
2) Remaining capacity = full charge capacity
3) Current intensity reduce to end charge current when constant voltage charge
4) Remaining capacity reach up the set value
Discharge
Constant current discharge for double loads
Inner load: 0 ~ 1000mA, adjustable continuously via Battery Manager
External load: 0mA, 500mA, 1000mA, 1500mA, 2000mA, five gears with dip switches offered
Tester will stop discharging if one of the conditions below is met.
1) Remaining capacity set value
2) Voltage set value
3) Current intensity reduce to zero
Remarks:
Many batteries can not measure exact current intensity, which cause an else current value appears after you set a value. However, the actual discharging current is the same with your set value.
Test
Testing time is 12 seconds and the purpose is to check both the charging and discharging performances. After finishing test, LED flickers with green color and LCD reports the test result.
Normal: Test OK Shown on LCD
Abnormal: Test NG Shown on LCD
Possible causes and solutions for the abnormal:
1) Cause: battery voltage is too low to discharge
Solution: try to charge the battery to raise voltage
2) Cause: remaining capacity is too full to charge any more
Solution: try to discharge the battery to reduce the remaining capacity
3) Bad contact of battery connecting wires
4) Damaged battery
5) Tester trouble
Capacity Correction
The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip.
Remarks:
Discharging current can be set via Battery Manager. Deep discharge will cause a battery losing communication with tester, so battery dropping phenomenon may happen in the discharging process if the end capacity and voltage are set too low. In such a case, active charge will make the battery work again.
50% Capacity
CD50%: charge firstly, and then discharge to 50% capacity
DC50%: discharge firstly, and then charge to 50% capacity
Online Functions
Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine.
Monitoring
Battery information can be monitored via three windows.
1. Home screen
Battery bar and brief information can be read on home screen.
2. Battery detail information window
Show smart battery data in real time and the data can be saved and printed in image format.
3. Battery graph window
Voltage, current and capacity are traced in curves.
Control
Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the related commands.
Attention
All the functions of charge, discharge, capacity correction and 50% capacity are comply with the charging discharging conditions, which are showed on function introduction paragraph in page 4 & 5, so parameters should be set reasonably. Especially, deep discharge will cause a battery losing communication with tester.
Others
1. Active cooling
2. Active batteries of zero voltage
When a battery is deep discharged, the discharge protection circuit will start up and the voltage in the battery connector will become zero voltage. In this case, an appropriate voltage should be supplied to active the battery.
3. Battery identification
Battery information can be read from battery management chip after establishing communication.
4. Intelligent protection
Against over-current, over-voltage, over-charge, over-heat and short circuit.
5. Fan

Other modes: fan startup when temperature above 48
Fan stop working when temperature below 40
6. Trouble alarm
LED flickers in red color and current command stops when one of the conditions below happen.
1). There is not current for around 50 seconds when charge.
2). There is not current for around 25 seconds when discharge.
3). Charging time is above 8.8 hours.
