Range: 0.000 … 30.000 V Resolution: 0.001 V
Current Measurement
The PCE-RTD 20 supports current measurement using either PCE-RTD 20 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, the PCE-RTD 20 does not provide 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, the PCE-RTD 20 works as Loop Power Supply while at the same time measuring
the current.
Voltage Measurement
The PCE-RTD 20 is 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 and simulating RTD. For RTD/ types refer to the specifications.
RTD/Resistance simulation
The PCE-RTD 20 is capable of RTD/Resistance generation. The following picture displays the connection for RTD and Resistance simulation. In RTD simulation RTD 20 mimics an RTD. The instrument under test generates the current for the RTD measurement. The PCE-RTD 20 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.

RTD/Resistance measurement
The PCE-RTD 20 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. The PCE-RTD 20 displays the selected
wiring system in run page. PCE-RTD 20 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 The PCE-RTD 20 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, the PCE-RTD 20 can compensate for the resistance of the connection wires.
4-Wire RTD Measurement The PCE-RTD 20 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.

In Periodic mode, changing of any Measure or Source parameter is not allowed. So
while Periodic Logging is Running, the user can’t enter into MEASURE, SOURCE and DISPLAY menu. But in Key Press Logging mode, there is no restriction.
In Periodic Mode, if an error message like “Not Sufficient Memory” comes while starting
the Logging, try reducing the logging time or increase the sampling period or try deleting some existing files.
In Key Press Mode, if the no. of samples reaches its maximum limit that is 484, the next sample will start from the first overwriting the memory.
While Logging is running, entering into the LOGGING menu shows below page.
for Periodic Mode for Key Press Mode
For Periodic Mode, this page contains information of Number of Samples Taken
and Time Remaining for Logging in HH:MM: SS.
Both Periodic and Key Press logging can be stop manually by pressing F1 key on
STOP LOGGING Button. For Periodic Mode, Logging will automatically stopped when defined log time ends and a message “LOGGING DONE” pops up.
