1 Terminal Connection for RTD Measure and Source and EM Measure 2 Keypad Section 3 Color Display 4 USB Connection Slot for PC Communication and Charging

2.2.1 Terminal Connections

EM Measure Terminals

Input Terminal for measuring voltage, current and supplying loop power.

EM Measure Terminals

Range: 0.000 … 24.000 mA Resolution: 0.001 mA

mA(24V)

Range: 0.000 … 24.000 mA Resolution: 0.001 mA

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/Ω 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.

2.2.2 KeyPad

The PCE-LOC 20 has six different keys. The key description is given below.

This key has different functionalities in different menus. These are shown in the bottom left part of the display.
