Averaging: None or moving average Lockout setting: Prohibiting certain operations; protecting settings DISPLAY Display: 6 mm (.6) high, ½ digits, 7-segment LED Display range: to 9999 Decimal point position: 0, 0, 0, 0 or none Zero indication: Higher-digit zeros are suppressed. Over-range indication: or 9999 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 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.
