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-47.
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.

2. TC-12 Hardware Parts & Accessories
2.1 Unpacking & Inspection
At the factory each new TC12 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:
Calibration Certificate
User Guide
1Test leads (2mm to 2mm )
1 Test lead Cu-Cu(Miniature TC Plug Cu type to 2mm Test lead)
2 Sets of 2mm Crocodile clips.
2 Sets of connecting plug 4mm to 2mm
USB A Male to USB mini B Male cable for PC communication and
charging.
5 VDC Charging Adaptor
Carrying Bag
TC-12 Configuration & Logging Software CD-mCAL.
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 ofTC-12
in this manual) has an example configuration of modules. The
configuration of your TC-12 may vary significantly from the one in the
picture.

Current Measurement
TC-12 supports current measurement using either TC-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 TC-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 modeTC-12 works as Loop Power Supply while at the
same time measuring the current.
