• Scaled range

• Alarm setpoint

• Hysteresis (deadband)

• Others

(Refer to the instruction manual for details)

Read rate: 40 times/sec. (25 msec.)

Averaging: None or moving average

Lockout setting: Prohibiting certain operations; protecting

settings

DISPLAY

Display: 16 mm (.63) high, 4 digits, 7-segment LED

Display range: -9999 to 9999

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.
