DISPLAY

Display: 16 mm (.63) high, 4 ½ digits, 7-segment LED
Display range: -19999 to 19999
Decimal point position: 10–1, 10–2, 10–3, 10–4 or none
Zero indication: Higher-digit zeros are suppressed.
Over-range indication: ‘-19999’ or ‘19999’ blinking for
display values out of the display range.
‘S.ERR’ and ‘Min’ or ‘Max’ blinking when the input signal is
out of the usable range.
Alarm status indication
L indicator: Green turns on when the L alarm is tripped.
H indicator: Red turns on when the H alarm is tripped.
P indicator: Amber turns on when none of the other alarms
is tripped.
Only ‘P’ turns on when no-alarm is selected with
alarm setpoint.
Function indicators:
Zro, Spn, D/P, Tch, Fnc, Min, Max
