Unit was dropped oroverloaded. Contact a dealer for repairLow bat displays even after theunit was charged for more thanone day.Voltage of battery is low. • End of battery life Contact a dealer for repair• Breakdown of battery• Breakdown of chargingIt doesn't display anything even ifpressing POWER Key.Battery is weak. Voltage of battery is lower. Please charge a battery.“BAT” isn't displayed onLCD even if charging up. • Breakdown of battery Contact a dealer for repair.• Breakdown of internalcircuit• Breakdown of AC adapterThe value becomes “0”automatically when measuringsmall value near 0.You can use tracking toprevent the fluctuation ofthe measuring value near“0”.Tracking is on. Please set tracking off.(Refer to“4.5.Tracking”)Value changes if you change thedirection of force gauge. This is not breakdown.This equipment ismeasuring the emptyweight of sensoron its own.Sensor or tools can addweight Push ZERO key aftersetting the direction tomeasure and clear themeasuring value.Although I downloaded“Toriemon”, it doesn't work even ifconnectingforce gauge. -Since “Toriemon” issoftware for RS-232Ctransmission,it doesn'trespond to USBtransmission.Please download“Toriemon USB” and use it.Questions Explanation ReferenceHow long does rechargeablebattery(Nickel hydride battery) last?Enable to use 500 times or more bycomplete electric discharge.

User cannot exchange battery. Ask our dealers to assist you with batteryreplacement.Do you have CAD data? Yes. Please contact our dealer.Is it possible to use in water? No. It is not waterproof structure. Please pay attention not to pour water.10.Support10.1.Repair and CalibrationWe recommend calibrating regularly for keeping up the accuracy of force gauge.
