Hioki-SS7012 เครื่องกําเนิดสัญญาณ DC

HIOKI DC Signal Source Model SS7012

The Hioki SS7012 is a compact DC signal source and calibrator that is used to perform maintenance or loop tests of instrumentation systems and can be operated from a computer via a USB cable. It can also be used to calibrate thermometers and measure DC voltage and DC current.

Key Features

• Improve stability and reduce calibration costs compared with the previous HIOKI model
• For instrumentation systems (4 - 20 mA) and loop testing
• Check temperature control equipment and electric distribution
• 8 types of thermocouples to test thermoelectric power generation
• Ideal for electrical device testing and routine maintenance of production equipment such as calibrators
• Use the max. 25 mA DC sink as an electric load

Loop test (two-wire transmitter sensor) Verifi es proper sensor output (two-wire transmitter sensors). The SS7012 applies distributor power to the sensor as a constantvoltage (CV) output, and monitors current output from the sensor.	Loop test(distributor) Test distributor operation. Apply the default current from the SS7012 as a substitute for sensor current output. Set SS7012 polarity to negative (to operate as a sink).
Thermometer calibration (TC, CV, and CC source) Substitute the output of sensors such as TC (thermocouple) voltage, current and resistance with TC, CV, CC and Rs (100 Ω) test signals from the SS7012.	Store up to 20 steps in memory Up to 20 levels can be stored for each source function, which can be recalled manually or in sequence automatically (auto scan). Use this function for meter checking, repetitive adjustments, and linearity testing.
Temperature measurement Use the optional 9184 Temperature Probe to measure temperatures from -25 to 80°C. As well as measuring ambient temperature, you can calibrate thermoelectric thermometers with reference junction compensation TC (RJ).	Portable, precise and stable Despite the small size and light weight, the high precision and stability of ±0.03% for CV and CC sourcing, and ±0.05% ±0.5°C* for TC (0°C) sourcing, have one-year guaranteed accuracy. The compact hand-held design is convenient for travel, fi eld calibration, and servicing applications. * For TC (0°C) sourcing of K, E, J, and T thermoelectromotive force .
Simultaneous voltage and current sourcing and display Source up to ±25.000 V and ±25.000 mA while measuring up to ±28.000 V and ±28.000 mA. Isolated source and measurement circuits can increase operating efficiency for applications such as simultaneous input and output testing of transducers using a single instrument.	Small source applications Use as a portable signal source for electronic device testing and evaluation. Full external control is available via the USB interface.* * Only for communicating with a PC. Accessing USB memory is not supported.
