DISPLAY

Display: 16 mm (.63) high, 4 digits, 7-segment LED
Display range: -9999 to 9999
Decimal point position: 10^-1, 10^-2, 10^-3 or none
Zero indication: Higher-digit zeros are suppressed.
Over-range indication: ‘-9999’ or ‘9999’ blinking for display values out of the display range.
Alarm status indication
LL indicator: Green LED turns on when the LL alarm is tripped.
L indicator: Green LED turns on when the L alarm is tripped.
H indicator: Red LED turns on when the H alarm is tripped.
HH indicator: Red LED turns on when the HH alarm is tripped.
P indicator: Amber LED turns on when none of the other alarms is tripped.
Only ‘P’ turns on with no-alarm-output type. ‘LL’ or ‘HH’ does not turn on with dual-alarm-output type.
All setpoints can be independently set either for Hi or Lo alarm trip.
