7. DISPLAY MESSAGES :
“OLOL” - Appears when measurement e signal range.
“ULUL” - Appears when measurement exceeds - signal range
“. . . .” - Appears when display values display range.
“- . . .” - Appears when display values exceed - display range.
8. CONNECTION TYPE : 4 or 6 wire bridge
9. COMMON MODE RANGE ( w.r.t. input common): 0 to +5 VDC
Rejection: 80 db (DC to 120 Hz)
10. SENSOR INPUTS :
* After 20 minute warm-up. Accuracy is specified in two ways: Accuracy
over an 18 to 28
°
C and 10 to 75% RH environment; and accuracy over a 0 to
50
°
C and 0 to 85%RH (non-condensing environment). Accuracy over the 0 to
50
°
C range includes the temperature coefficient effect of the indicator.
** The indicator periodically (every 12 seconds) imposes a 500 msec delay
to compensate for internal zero drift. If the delay affects applications where step
response is critical, it can be defeated. Set the display update to 20/sec to
disable. In this case, add a zero error of 0.2% FS to the 24 mV input range over
the 0 to 50
°
C span.
