简介：STD-2000, 标准校准仪
- 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.
