Accuracy Assurance Period

1 year With better engineering that makes time-dependent changes smaller (in both generation and measurement), this period is actually longer in practical terms.

1 year; however, two accuracy specifications (6-month/1-year) are specified. In addition, the accuracy for 1-year is two times worse than that for 6 months.

2. MAJOR APPLICATIONS FOR MODEL SS7012

-1. Maintenance of Instrumentation Equipment (Loop testing)

1) Test of 2-wire Transmitters

The SS7012 can generate up to 25V of DC voltage and monitor up to 28mA of DC current simultaneously. With this feature, you can simulate performances of 2-wire

transmitters (such as Temperature meters, Pressure meters, Flow meters and the

like) used in factories, generating stations, buildings, vessels, disposal centers, waterworks, sewage centers, etc.

2) Test of Distributors

Can accept up to 25mA of load current (DC) from the 24VDC voltage output

terminals of the EUT. With this feature, you can simulate performances of

Distributors (Allotters).

Pic. 2-1: 2-wire Transmitter

3) Other Equipment

With its 1-5VDC output capability, you can also simulate performances of

Meters/Indicators. The SS7012 can save output settings like 4/8/12/16/20mA or 1/2/3/4/5V (for

meters) and then generate it repeatedly. This function drives better efficiency

during maintenance of instrumentation instruments.

-2. Simulation Signal for Manufacturing Facilities, Automated Machines,

Manufacturing Equipments for Semiconductors, etc.

Because the SS7012 is a battery-activated instrument, generates +/-25VDC or +/-25mADC and has a high accuracy specification, i.e., ±0.03%±300 V @ 2.5V

range, at its “mV” generation function, you can use it as simulation signals before

connecting various sensors that are connected to automated facilities or power conditioners or controlling equipment.

-3. Calibration of Temperature Meters

Model SS7012 can generate a thermocouple-output equivalent signal from 8 kinds (K, E, J, T, R, S, B and N) of thermocouples for temperature meter calibration. Also,

the SS7012 lets you setup generation settings in the actual temperature values (not

voltage values).

The SS7012 also has the capability to generate resistance values (100ohm),

allowing you to confirm the 0°C level of temperature meters that use a Pt100

thermister (not with thermocouples).

Because the SS7012 is a light-weight and highly-portable instrument, it offers better efficiency with this type of simulation work.

Can be used as calibration input signals on temperature meter calibration or as pseudo-output signals from temperature sensors.

With the optional 9184 RJ Sensor, you can calibrate temperature meters when the ambient temperature is used as the reference temperature value.

(when ambient temperature is regarded as the reference temperature value)

-4. Design and Evaluation of Electronic Equipment

Because Model SS7012 can simultaneously generate and monitor current or

voltage), you can apply it as a power source to various modules or electronic devices. You can also use the SS7012 as a precision power supply or a load for

small equipment, instruments or devices.

In addition, the generation circuits and the measurement (monitoring) circuits of the

SS7012 are isolated from one another, allowing you to monitor the output signal of electronic instruments or devices that is being applied with a signal generated by

the SS7012 at the very same time.

3. ADVANTAGES OF MODEL SS7012

-1. Generate +/-25VDC or +/-25mADC even when only using batteries to

power the unit

Output Voltage : +/-25VDC (1mV resolution)

: +/-2.5VDC (100 V resolution) Output Current : +/-25mADC (1 A resolution)

Therefore, you can conduct “Loop tests” of instrumentation equipment accurately.

-2. Generation (Output) Circuits & Measurement (Monitoring) Circuits Isolated

Because the generation (output) circuits and the measurement (monitoring)

circuits of the SS7012 are isolated, you can monitor voltage or current measurements while generating the same.

-3. Measure Load Current, Load Voltage, Ambient Temperature, etc. using the

Measurement (Monitoring) Function

You can measure load current or load voltage while generating the signal from the SS7012. You can also monitor ambient temperature if you connect the

optional 9184 RJ Sensor to the SS7012.

-4. Generate 8 kinds of Thermocouple-equivalent Signals

(”N” is newly-added to the SS7012.)

SS7012 allows you to generate voltage signals in accordance with 8 kinds (K, E,

J, T, R, S, B and N) of thermocouples which the IEC 584-1 has registered. You can set up the output voltage in temperature values, enabling you to perform

efficient calibration of temperature meters with thermocouples.

Because the basic accuracy of the SS7012’s output signal is quite high at 0.03%, you can satisfy the requirements of customers who require good accuracy.

Simultaneously evaluate input and output characteristics of low-voltage electronic devices. Differences in potential between generation circuits and measurement circuits MUST be within 60VDC.

With this feature, you can easily conduct “Loop tests”!!

For temperature meters with a thermister, you can also check 0ºC using the 100ohm (Pt100) Output Function of the SS7012.

-5. Memory Generation Function

You can store up to 20 steps of generation for each of the 4 Generation Functions

(Voltage, Current, Thermocouples and Pt100) into the internal memory of SS7012. Also, you can generate the stored settings by using the RECALL mode

(i.e., recall settings manually) or SCAN mode (i.e., automatic sequential output).

-6. Ni-MH Rechargeable Battery or AA Alkaline Battery Operation

You can power the SS7012 simply with 4 pieces of commercially-available Ni-MH

Rechargeable Batteries (AA type) or AA Alkaline Batteries.

* Please note that HIOKI cannot assure the exact duration of continuous

operation because each battery has different characteristics.

-7. External Control via the USB Interface

With the optional SS9000 Communication Package (including 1 USB Cable and 1

USB Driver Software), you can externally control the SS7012 from your PC.

* Please note that the USB Interface on SS7012 is not for memory sticks.

The SS9000 consists of only the USB cable and driver. To externally control the SS7012, download and install the free application software, available soon from the HIOKI website.

Rechargeable batteries must be recharged by a commercially-available charger. (Not by the SS7012 itself)

Having 8 pieces of fully charged rechargeable batteries can alleviate any anxieties about

battery-low problems on site.

A step-by-step voltage output, which is widely used in the maintenance of instrumentation equipment (i.e., 1, 2, 3, 4 and 5V outputs), is equipped in the 25VDC Output Function.

Also, a step-by-step current output, which is widely used among 4-20mA applications (that is, -4, -8, -12, -16 and -20mA outputs), is equipped in the 25mADC Output Function. Please note that those current values are indicated as minus values because the “4-20mA” output is used for current absorption.
