Menu selections 03, 04, 05, and 06 set the criteria for delay and threshold that have to be
met for a change in output signal.
Set the rotary switch to 7. To change the mode to 2-state High, press the RED (+) button
for more than one second: the LCD displays C: Hi. When the button is released, the loop-
current will switch to 20 mA if the probe is covered, or 4 mA if it is uncovered.
To change the mode to 2-state Low, press the BLUE (–) button for more than one second:
the LCD displays C: Lo. When the button is released, the loop-current will switch to 4 mA,
and if the probe is uncovered, or 20 mA if the probe is covered.
Analog Mode may be restored at any time by pressing both buttons simultaneously for
more than one second. The LCD displays C: An while the two buttons are pressed, and
displays the current reading when the buttons are released.
The loop-current will be between 3.8 and 20.5 mA, and will saturate to one of these
values if the level goes beyond the Upper or Lower range settings.
