at the rear LOGIC I/O CONNECTOR or by a RELEASE (RLS) command
received through the RS-232/485 Interface (see Appendices B and F).
To change the HIGH LATCH status, you can toggle between ON and OFF by
pressing the top or bottom segment of any display character.
j. When the desired HIGH LATCH status appears, press ENTER to return to the
"HILAT" display. Then press LIMIT again. The unit will display "LOL" (for "LOW
LIMIT").
k. Proceed to set the LOW LIMIT ("LOL"), LOW HYSTERESIS ("LOHYS"), and LOW
LATCH ("LOLAT") just as you did for the HIGH LIMIT. The LOW LIMIT value
cannot be greater than the existing HIGH LIMIT, and, like the HIGH LIMIT, auto-
matically assumes the decimal-point precision of the existing SCALING FAC-
TOR ("m"). The LOW HYSTERESIS WINDOW is just like the HIGH HYSTERESIS
WINDOW, except that it works in the opposite direction and with reference to
the "LOW LIMIT VIOLATION."
l. After you have entered the desired LOW LATCH status by pressing ENTER ,
press SETUP to return to the "Setup" display.
NOTE: You can include LIMIT-ZONE INDICATION in the data transmissions. See
Section 3.a.10, below, for instructions.

By means of the TARE/RESET button in SETUP MODE, you can establish a tare
offset to be continuously subtracted from the "live" data reading whenever the
unit is in "TARE" MODE. To do so,
a. Once you are in SETUP MODE, press the button labelled
The unit will display the word "TARE":
b. To display the contents of the unit's TARE REGISTER, press
The number in the TARE REGISTER represents the net data reading you want
to see (for the current value of input loading) when the tare offset has been
subtracted. It should be expressed in the desired engineering units and will
automatically reflect the existing precision of the SCALING FACTOR ("m").
When the unit is placed in "TARE" MODE,* the displayed data reading will be
brought to the existing TARE REGISTER value. From this point, the displayed
data will continue to track the "live" input, but now with the continuous applica-
tion of the offset determined by the difference between the reading that exist-
ed when "TARE" MODE was initiated and the last-entered TARE REGISTER
value (see Fig. 24, Section 5.c).
