簡介：STD-2000, 標(biāo)準(zhǔn)校準(zhǔn)儀
  • Desired value setting is possible by choosing a number for each digit.
  • Five ranges can be switched respectively for each function of DC current, DC voltage, AC voltage, and AC current. The resistance is comprised of two types of terminals: a common terminal for 0-200kΩ and 10Ω step, and a terminal dedicated for switching of 6 ranges between 190Ω and 19MΩ.
  • Use of electronic soft-touch push button switches except the power switch. Speedy value setting and operation are possible. The relay of the low thermal electromotive force type and semiconductor switch are used for circuit switches to enhance heat resistance and durability.
  • Overload protection in case of low voltage and current is performed on the semiconductor circuit, and overload protection in case of medium and high voltage is achieved by releasing the output terminal and output voltage circuit to assure safety. When overload current runs in the voltage range of 20V or more, the LED for DC and AC resetting lights up to give warning.
