Debug Level 
 
P086  Ping Delay (From Software Revision 6.4.1) 
This parameter is used to delay the time between each ping in order to prevent the 
risk of a second ping interfering with the initial return echo and causing 
problematic readings. It delays the time between each ping. 
 
P087 Fail Time 2 
 
 
This parameter determines the time after an event, such as “Loss of Echo”, that a 
warning message will appear in the Auxiliary line of the display. 
Values:  Min. 0.1 min 
  Max. 9999 min 
 
P088 Hard Default 
 
 
P88 allows both User and Service parameters to be reset to their Factory Default 
values. 
N.B. P930 Factory Defaults will allow the user to reset only those parameters 
which are accessible via the User Passcode (Default 1997), but will not reset any 
parameters which are accessed via the Service Code 552621. Thus ensuring any 
adjustments carried out by Service personnel are protected. 
Options:  
0 = No 
1 = Yes
