programming

Linearization: Standard

Setting: (Front button)

• Input type

• Alarm setpoint

• Hysteresis (deadband)

• Moving average

• Others

(Refer to the instruction manual for details)

Sampling rate: 20 times/sec. (50 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: -1999 to 9999

Minimum display/setting scale: 0.1°C or 1°F

Zero indication: Higher-digit zeros are suppressed.

Over-range indication: ‘S.ERR’ and ‘Min’ or ‘Max’ blinking

when the input signal is out of the usable range.

Burnout indication: ‘B.ERR’ blinking

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:

Ini, Alm, D/P, Adj, Fnc, Min, Max
