For all kinds of resistance weldingWELDING CURRENT METERＳＰ-３２８８ / ＳＰ-３２９０(Data Output from USB port)■ Outline :Model SP-3288 is handy type welding meter of secondary current and welding time for all kindsof resistance welding. Sensor is MEKANO patented toroidal coil for precise current detection.Measured data is digitally indicated in the display and stocked in built-in memory.RMS effective value calculated at each half cycle or Peak value of welding current is displayedtogether with welding time and conduction angle.In case of capacitor discharge type welder, it measures and displays peak value of current andtime(mSec) to peak current or time(mSec) to the end of current application.■ Features :◇ ・ More compact lighter body and touch key is improved for easier operation.◇ Measured data of maximum 100counts are stocked in built-in memory .◇ Wide range for measurement (Current: Max. 99.9kA, Time: Max. 999.5CY 2000ms) ／◇ The unit displays measured data; "Count No.", "Current (kA)", "Welding time (cycle / ms)"and "Conduction angle".◇ Additional new functions support measurement of designated time scope for any current typeand designated pulse number for multi-pulse current application.■ Data Output : (SP-3290)◇ SP-3290 has USB port for transfering the measured data as below to PC.[Data 1] Date(Y/M/D/H/M/S), Count No, Current value, Welding time, Conduction angle[Data 2] Divisional data per 1cycle (20mSec/16.7mSec at 50Hz/60Hz) for each welding count.[ Capacitor discharge type ] : Divisional data(time) per 10% of peak value.◇ Free software for PC application is available at Spotron website.■ Specifications :■ Option: Soft case for main unit, Toroidal coil PU-14[18φx800mm (260φ)]Made in Japan [May change without the preliminary announcement of a part of appearance and specification by product improvement etc. ] 2018.12Manufacturer Specialized in the measuring equipment for resistance welding DistributorMEKANO CORPORATION3-10-15, SIMO-ASAO ASAO-KU KAWASAKISI-SHIKANAGAWA  Single phase/3phase AC, Rectified Current, AC/DC Inverter, Capacitor discharge, Intermittent seam weld, etc.Ranges 0.50kA～9.99kA / 2.50kA～25.0kA / 10.0kA～99.9kAValue RMS value or PEAK value ±2% F.S. / RMS±(2%rdg+3dgt), PEAK±(2%rdg+9dgt) * Either the above two values which is smaller.
