LIMIT
. During the RUN mode, this key is only operative in
case that the instrument incorporates one of the following
output options: 2 relays (ref. 2RE), 4 relays (ref. 4RE), 4
NPN transistors (ref. 4OP) or 4 PNP transistors (ref. 4OPP).
At one push of "LIMIT" key the display illuminates the "limit"
LED and reads the first programmed setpoint value with the
LED 1 activated. New strokes on the LIMIT key recall
successively the rest of the setpoints with the corresponding
LED (on the right) activated.
The setpoint values are shown at each push of the "LIMIT"
key independently of whether they are enabled or inhibited.
15 seconds after the last key operation or by a push of
"LIMIT" from the visualisation of the last setpoint, the
auxiliary display blanks and the meter returns to the normal
reading.
