P800 Display Units 
This  parameter  determines  whether  the  reading  displayed  is  in 
Measurement Units (P104), or as a percentage of span. 
Display is in Measurement Units (P104) 
Display is in percentage of span. 
 
 
P801 Decimal Places 
This parameter determines the number of decimal places on the reading 
during run mode.     
Minimum = 0 (No decimal places), Maximum 3 = (3 decimal Places) 
Default = 2 
P808 Fail-safe Mode 
By  default,  if  a  fail-safe  condition  occurs,  then  the  display  and  the  mA 
output are held at their last known values until a valid reading is obtained. 
If required, then you can change this so that the unit goes to high (100% of 
span), or low (empty) as follows: 
Remain at the last known value 
Will fail to the high value (100% of Span). 
Will fail to the low value (empty) 
 
P809 Fail-safe Time 
In the event of a fail-safe condition occurring the fail-safe timer determines 
the time before fail-safe mode is activated. Default = 2.00 mins 
If the timer activates, the unit goes into fail-safe, as determined by P808, 
(Display  and  P840  (mA  Output).  When  this  happens,  you  will  see  the 
message “LOE!” on the display. 
When a valid measurement is obtained then the display and mA output will 
be restored and the timer is reset.
