1.2 Description
The 7007 LoopMate 2 is a dedicated loop signal indicator (RxSim) with an in-built 24 V loop
drive supply (TxTest). The operator can select the loop type, and also the type of units,
either direct (mA) or % of span display. The loop signal is shown on an easy-to-read LCD
display to an accuracy of 0.05% either in mA, V, or % of span.
It is a cost-effective process instrument suitable for service and maintenance engineers. It
combines simple operation with the accuracy required for most process applications. Used in
conjunction with the 7006 LoopMate 1 they provide full process loop testing capabilities,
facilitating quick location of faults, testing and re-calibration.
In addition to TxTest (transmitter test) and RxSim (receiver simulation) the 7007 can be used
to measure DC voltage in the process loop up to 50 V.
The unit is powered by a PP3 type battery. Rechargeable batteries can be used if required.
It comes complete with carrying pouch, leads and user manual.

3Operation
3.1 Function Select
The Loop-Mate 2 has 3 functions:
1. Function 1 ..................Rx SIM
2. Function 2 ..................Tx TEST
3. Function 3 ..................Meas Volt DC
These are selected using the function select switch.
3.2 Display Select
For RxSim and TxTest the signal can be displayed either direct (mA) or % of span.
These are selected using the display select switch, which also turns off the Loop-Mate 2.
3.3 Description of typical process loop components
4 - 20 mA process loop
0 - 10 V process loop
4-20 mA Process loop
and
4 - 20 mA Control loop.
This can be used for
closed loop control.

Tx (transmitter):
This component converts physical signals such as pressure, temperature, flow, and level
etc, into the loop signals (4 - 20 mA or 0 - 10 V).
Rx (receiver):
This component measures the loop signal and either displays it (indicator) or converts it to
another form e.g. digital output for control purposes, (controller).
Process Controllers:
This device usually contains both Rx (signal loop) and Tx (control loop) components, which
operate in separate loops. The Rx and Tx can be either 4 - 20 mA or 0 - 10 V.
Loop excitation supply:
A DC power supply (nominally 24 V) that drives the loop.

3.4 Rx Sim function
The unit displays the loop current in either mA (0-50 mA) or percentage of span (4-20 mA),
depending on the position of the display select switch.
3.4.1 Operation
1. Connect the unit to the process loop observing the correct polarity.
2. Set the function switch to RxSim.
3. Turn the unit on, selecting the desired display units, using the display switch.
Note: If the loop current is less than 4 mA, negative % of span will be displayed.
