Hioki SS7012 DC Signal Source

• For Instrumentation systems (4 – 20 mA) and loop testing
• Improve stability and reduce calibration costs compared with the previous HIOKI model
• Check temperature control equipment and electric distribution
• 8 types of thermocouples to test thermoelectric power generation

Loop test (two-wire transmitter sensor)

Verifies proper sensor output (two-wire transmitter sensors). The SS7012 applies distributor power to the sensor as a constant voltage (CV) output and monitors the 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.
