• Input type

• Alarm setpoint

• Hysteresis (deadband)

• Moving average

• 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 ½ digits, 7-segment LED

Display range: -19999 to 19999

Zero indication: Higher-digit zeros are suppressed.

Over-range indication: ‘-19999’ or ‘19999’ blinking for

display values out of the scaled range.

‘S.ERR’ and ‘Max’ blinking when the input signal is out of

the usable range.

Alarm status indication

LL indicator: Green turns on when the LL alarm is tripped.

L indicator: Green turns on when the L alarm is tripped.

H indicator: Red turns on when the H alarm is tripped.

HH indicator: Red turns on when the HH alarm is tripped.

P indicator: Amber turns on when none of the other alarms

is tripped.

Note: 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.

Function indicators:

Zro, Spn, D/P, Tch, Fnc, Min, Max
