Double integral method
Sampling time
0.5 s
Display refresh period
0.5 s
Process value averaging method
Simple average/movement average
No. of process value averaging
operation
1, 2, 4, or 8 times
Max. displayed digits
4 digits (--1,999 to +9,999)
Display
7-segment red or green LED with a character height of 14.2 mm
Decimal display
Selected by the Up and Down Keys and parameter selector
Scaling function
Shift/Scaling adjustment is possible with the Up and Down Keys and parameter selector
Scaling range
--1,999 to +9,999
Zero-limit range
0to99digits
Overflow display
Flashes
Zero-suppress function
Available
External control
Process value hold (by short-circuiting the rear terminals)
Enclosure rating
Front panel: IP51 (see note)
Case: IP20 Refer to IEC
