Volume-less system (nonadjustable circuits)

• Adoption of the volume-less system (nonadjustable circuits) enables a high degree of stability to be secured.
• Our charging/discharge testers come in a wide range of currents (200A, 150A, 100A, 50A, 20A, 10A, 6A, 5A, 3A, 2A, 1A, 100mA, 60mA, 30mA, 15mA, 10mA, 3mA, 1mA, 500μA, 100μA, 10μA FS) compatible with all sorts of electric double layer capacitors and secondary batteries.
• This system realizes high precision voltage and current of ±0.05%FS (rising to 0.1%, 0.2% or 0.4% FS in some cases).
• Adoption of five-digit displays in all products enhances test accuracy.
• Since charging/discharge testers possess auto-range functions (2 ranges or 2 x 3 ranges) concerning current measurement, testing can be performed to even higher levels of precision.

Automatic Calibration Device (Securing of Traceability)

• Use of automatic calibration devices facilitates automatic correction and calibration.
• Automatic calibration devices can calibrate individual units even while other units are in operation.
• Since automatic calibration sets can be leased out, users can freely schedule calibration according to their own needs.
• Since automatic calibration is conducted with only the four-terminal cable detached, stable calibration can be performed under the actual temperature of use.

Battery Swell Measurement (Patented)

• Battery swell and temperature are measured in real time while conducting charging/discharge testing.
• Available for use with square batteries and laminated batteries.

Multi-Battery Chucking Holder (Patented)

• We have a universal size battery holder that can hold the battery in the form to serve both cylindrical and rectangular.
• Holders are internally fitted with temperature sensors enabling temperature to be measured during testing.
• Protective covers can be attached to battery holders to mitigate explosive fly-off and direct winds.

Processing Speed

• Since units are fitted with CPUs, charging/discharge data processing is speeded up.
• Each unit computes current capacity and power capacity, and all data are stored in a server via LAN.
• Units can compile graphs and tables in extremely rapid time.
