General
warnings
WARNING
It is dangerous to ignore the specified limits for
the instrument or its related accessories.
Do not use the instrument or accessory if it is not
in its normal condition.
Use the applicable protection and obey all safety
precautions.
Do not use the instrument in locations with
explosive gas, vapor or dust. There is a risk of an
explosion.
Electrical
warnings
To prevent electrical shocks or damage to the
instrument, do not connect more than 30V
between the terminals, or between the terminals
and the ground.
This instrument uses a Lithium-Ion battery pack.
To prevent an explosion or fire, do not short
circuit, do not disassemble, and keep it safe from
damage. For operating conditions, see section 6.1
on Page-47
To prevent battery leakage or heat generation,
only use the battery charger in the temperature
range 0 to 45°C (32 to 113°F). For operating
conditions, see section 6.1 on Page-49.
To make sure the display shows the correct data,
disconnect the test leads before you set the
power to on or change to another measure or
source function.
Cautions
To prevent damage to the display, do not use
sharp objects on the screen.
Before you start an operation or procedure in this
publication, make sure that you have the necessary
skills (if necessary, with qualifications from an

6of 52| P a g e User Manual
approved training establishment). Follow good
engineering practice at all times.

2. RC-12 Hardware Parts & Accessories
2.1 Unpacking & Inspection
At the factory each new RC12 passes a careful inspection. It should be
free of scrapes and scratches and in proper operation order upon
receipt. The receiver should, however, inspect the unit for any damage
that may have occurred during transit. If there are signs of obvious
mechanical damage, package contents are incomplete, or the
instrument does not operate according to specifications, contact the
purchasing sales office as soon as possible.
The standard accessories are as follows:
If you have to return the instrument to the factory for any reason, use the
original packing whenever possible. Include a detailed description of the
reason for the return.
2.2Operational Sections and Connections
All sections and connections are presented in detail on the next pages.
Note: Keep in mind that the next picture (as well as all pictures of RC-12
in this manual) has an example configuration of modules. The
configuration of your RC-12 may vary significantly from the one in the
picture.

Current Measurement
RC-12 supports current measurement using either RC-12 as the
loop power supply while at the same time measuring the current or
simply measuring the current while an external power supply is
used.
The following picture displays the connection for Current
Measurement for different mode. And also different ways of
providing the supply power to the loop.
mA Current Measurement
In this mode RC-12 not providing any supply voltage. For
proper measurement the external device should capable of
providing the voltage supply. If the external device should not
capable, an external Power Supply should be connected in
series.

mA Read Power Current Measurement
In this mode RC-12 works as Loop Power Supply while at
the same time measuring the current.
Voltage Measurement
RC-12is capable of voltage Measurement with two voltage
measurement ranges.
The following picture displays the connection for Voltage
Measurement for different mode.
RTD Terminals
Terminals for measuring & simulating RTD. For RTD/Ωtypes refer
specification sheet on page 50.
RTD/Resistance simulation
RC-12 is capable of RTD/Resistance generation. The following
picture displays the connection for RTD and Resistance
simulation. In RTD simulation RC-12 mimics an RTD. The
instrument under test generates the current for the RTD
measurement.
RC-12 controls the voltage across its terminals so that the
resistance (voltage to
Current ratio) corresponds to the simulated temperature. Use of 2-,
3-or 4-wire connection is up to the receiver instrument. Use only
the two leftmost terminals with every wiring option. Connect the
possible third and fourth wire according to the
Requirements of the connected instrument but use only the two left
most terminals.
