该万用表便携性强，尺寸为113毫米（高）×53毫米（宽）×10毫米（厚），重量仅为78克。它使用3V CR2032电池供电，测量速率可达3次/秒。此外，KT-22还具备数据保持、超程显示和自动关机功能。
English Introduction
The KT-22 digital multimeter is a high-precision and multifunctional device produced by Japan s KAISE company. It features a large LCD display that provides clear readings with a resolution of 4000 digits and a character height of 19mm. The multimeter is equipped with a variety of measurement functions, including direct current (DC) voltage, alternating current (AC) voltage, resistance, frequency, continuity testing, diode testing, and electrostatic capacity.
In terms of DC voltage measurement, the KT-22 has a range from 400 millivolts to 600 volts, with a precision as high as ±1.0% of the reading. For AC voltage measurement, the range is from 4 volts to 600 volts, with a precision up to ±2.0% of the reading. Resistance measurement ranges from 400 ohms to 40 megaohms, with a precision up to ±1.0% of the reading.
The KT-22 is designed for portability, with dimensions of 113mm (height) × 53mm (width) × 10mm (thickness) and a weight of only 78 grams. It is powered by a 3V CR2032 battery and has a measurement rate of up to 3 times per second. Additionally, the KT-22 features data hold, over-range indication, and automatic shut-off functions.
