EXTREME1 Digital Data Recorder

On-Board Shunt Test
The EXTREME1 incorporates a unique feature, a built-in Shunt Test, with user-selected shunt resistance.  Use the Function button to scroll to ARM. Then, while pressing the UP or DOWN button, press the SELECT button to start the SHUNT TEST.  A recording of a shunt sequence will automatically be made.

The recording will consist of 0.06 seconds of nominal  signal,  0.1 seconds of a user-select resistance shunted between the sensor supply and the sensor positive output, then a final 0.063 Seconds of nominal signal.  These times were selected in order to fit the complete Shunt Test sequence into a single sub-file (1/10 total memory).
