Test Plug Procedure
If you come across an operating problem, the Test Plug gives information that can let you know if a
Sensor, Monitor or Transmitter is working correctly. The Test Plug sends a constant electronic signal to
the Monitor. This data can be read on the Monitor Signals screen. The normal signal range is about
24-29 nA (nanoamperes).
1. Disconnect the Sensor from the Transmitter’s Sensor connector.
2. Press the SEL button until the SEARCH screen appears, and start the search for the Transmitter. See
Chapter 2: Getting Started.
3. Connect the Sensor Connector end of the Transmitter to the Transmitter Connector end of the Test
plug (see Figure 4.1). Press the parts together until the snap arms on the Cable Connector come
together with a click.

If the Monitor recognizes the Transmitter, the Monitor will enter the Initialization mode. The
Monitor will display INIT and 2:20 h.
5. The Monitor will count the minutes down from 2:20 h. Data is first sent in the 2:13 to 2:10 h. To
check the correct ISIG values (ISIG stands for Input Signal, which is the Sensor current) you must
wait for data to be first sent. Let the Monitor reach this range in time; it will take between seven to
ten minutes. This wait period ensures that the reading from the Transmitter is stable.
