Elapsed Time Counter
The system records, as a background task, the total running hours of the unit and the pump running
hours. This facility assists with the scheduling of the 1000 hour and 3000 hour servicings.
Auto Zero
• This function optimizes airspeed accuracy at low airspeeds. The ADTS 505 performs an auto
zero when the following conditions are met:
1. The ADTS 505 is in Leak/Measure mode.
2. Ps and Pt pressures are stable.
3. The airspeed is less than 20 knots (or Qc equivalent).
• The auto zero starts five minutes after entering Leak/Measure mode providing conditions 2
and 3 are met and thereafter, every five minutes.
• The auto zero sequence can be interrupted at any time by entering a new command (key
press).
Hand Terminal Option A
• The hand terminal option connects to the front panel through an 18 metre cable and
connector. Both the hand terminal and front panel key-pad and display provide the same
information. All selections that can be made by the front panel key-pad can be made by the
hand terminal key-pad.
• The system auto-detects the hand terminal at power-up or when connected and
automatically disables the front panel key-pad. The front panel display can be set to show
the message "Remote Hand Terminal Operating" or to monitor mode showing the current
values and modes selected by the hand terminal. In monitor mode the front panel display
shows only these values and modes but no function key selections.
• To change between message and monitor selections go to set-up, display, F6 Hand Term
[Monitor]. Press F6 to switch between [Monitor] and [Message].

up-load and down-load user-defined test programs. When connected the system auto-
detects the advanced hand terminal and disables the front panel key-pad. The front panel
display shows "Remote Hand Terminal Operating" (message/monitor) or the current values
and modes of the advanced hand terminal (monitor). The display (Figure 6-6) shows the main
operation menu with selections for system set-up, test sequence file screen and manual
control screen.
