2. UC-12 Hardware Parts & Accessories
2.1 Unpacking & Inspection
At the factory each new UC-12 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.

EM (Electric Measurements and 24V Supply) Measure Terminals
Input Terminals for measuring voltage, current, supplying loop power,
and Frequency and pulse types refer specification sheet on page no.
95 Section 6.6 and page no. 97 Section 6.13, 6.14.
Current Measurement
UC-12 supports current measurement using either UC-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 UC-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 UC-12 works as Loop Power Supply while at the
same time measuring the current.
Voltage Measurement
UC-12 is capable of voltage measurement. The following picture
displays the connection for voltage measurement.
Frequency Measurement
UC-12 is capable of frequency measurement. The following picture
displays the connection for frequency measurement.
Also check the Trigger Level setting. There you can specify the
trigger level and whether to use a test voltage during the frequency
measurement

User Manual P a g e | 11 of 100
Pulse Count Measurement
UC-12 is capable to count number of pulses. The following picture
displays the connection for pulse count measurement.
Check the Trigger Level setting to specify the trigger level and
whether to use a test voltage during the pulse counting. Also check
the Trigger Edge (Rising or Falling) setting so it suits your need.

RTD Terminals
Terminals for measuring & simulating RTD / Ω. For RTD/Ωtypes refer
specification sheet on Page No.95- 97 Section 6.8, 6.9, 6.10, 6.11
RTD/Resistance Source
UC-12 is capable of RTD/Resistance generation. The following
picture displays the connection for RTD and Resistance simulation.
In RTD simulation UC-12 mimics an RTD. The instrument under test
generates the current for the RTD measurement.UC-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 leftmost terminals.

RTD / Resistance measurement
UC-12 is capable of RTD/Resistance measurement. The following
picture displays the connection for RTD and Resistance
measurement.
2-Wire RTD Measurement
Two leftmost terminals are used in 2-wire systems. UC-12
displays the selected wiring system in run page. UC-12
sources current through the resistor and measure the voltage
drop across same terminals. The result is acceptable, if the
resistance of the connection wires is significantly smaller than
actual measured resistance.
3-Wire RTD Measurement
UC-12 sources current through the resistor and measure the
voltage drop across the entire current loop and across the
upper side connection wire as shown in figure. If both left side
connection wires are identical, UC-12 can compensate for the
resistance of the connection wires.
4-Wire RTD Measurement
UC-12 sources current through the resistor from two left side
terminals and measure the voltage drop across the resistor
from the two right side terminals. The 4-wire method gives the

resistance between the terminals of the resistor; it is
insensitive to the resistance of the connection wires.
