DC SIGNAL SOURCE
Signal Source & Calibrator
SS7012
DC Signal Source Supplies and
Measures Signals Simultaneously
The HIOKI DC SIGNAL SOURCE SS7012 can be used not only for instru-
mentation system (4-20 mA) maintenance, but also for maintaining and servicing
thermostatic devices, distributors, and industrial meters, as well as for evaluating
electronic circuits and devices, and for production facility maintenance.
The signal source also supplies thermoelectromotive force corresponding to eight
types of thermocouples. Furthermore, this compact DC signal source simultane-
ously sources and measures signals.

Two-Wire
Transmitter
Sensor
4-20 mA
Veri es proper sensor output (two-wire transmitter sensors). The
SS7012 applies distributor power to the sensor as a constant-
voltage (CV) output, and monitors current output from the sensor.

4-20 mA
Test distributor operation. Apply the default current from the
SS7012 as a substitute for sensor current output. Set SS7012 po-
larity to negative (to operate as a sink).
Loop test (distributor)
Substitute the output of sensors such as TC (thermocouple) volt-
age, current and resistance with TC, CV, CC and Rs (100 Ω) test
signals from the SS7012.

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.

Use the optional 9184 Temperature Probe to measure tempera-
tures from -25 to 80°C. As well as measuring ambient tempera-
ture, you can calibrate thermoelectric thermometers with refer-
ence junction compensation TC (RJ).
Temperature measurement
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, eld calibra-
tion, and servicing applications.

Output
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.
