specified panel cutout
Connection: M3 screw terminals
(nickel plated steel; torque 0.6 N·m)
Material: Flame resistant resin (black)
Scaling: Programming via the front buttons
Averaging: None or moving average
Security: Prohibiting certain operations; protecting
settings
DISPLAY
Display: 16 mm (.63) high, 4 digits (-1999 to 9999),
LED
Scaling: No scaling (input temperature indication)
Decimal point position: 10 –1 or none (fixed depending upon
the input type)
Minimum display/setting scale: 1°C or 1°F (0.1°C for K
and J, narrow span)
Read rate: Max. 40/second (25 milliseconds)
Over-range indication: ‘S.ERR’ flashing when the input
signal is out of the usable range.
Burnout indication: ‘B.ERR’ flashing
Alarm status indication*
LL indicator: Turns on when the LL alarm is tripped.
L indicator: Turns on when the L alarm is tripped.
H indicator: Turns on when the H alarm is tripped.
HH indicator: Turns on when the HH alarm is tripped.
P indicator: Turns on when none of the other alarms is
tripped.
Zero indication: Higher-digit zeros are suppressed.
Engineering unit indication: Sticker label attached
*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.

Input compensation
Input compensation: Offset temperature value is added at all measuring points. No gain setting.
Analog output 0% / 100%: 0% value < 100% value
Analog output 0% / 100% adjustment: Pressing [Shift] button switches the signal to increase or decrease, and then pressing [Up]
button controls it toward the desired output value. 0% value < 100% value
*1. °F indication is not available for K2 and J2 input type.
*2.
-199.9 to 999.9
for K2 and J2 input type
.
Temperature values must be re-set if the decimal point position is shifted due to an input
type change from K2/J2 to other types, or to K2/J2 from others.
