The Zero/Span valves can be set up to operate automatically. Table 6-2 in this section describes 
Autocal setup. 

1. 

Press SETUP-ACAL 

This button sequence will cause the AUTOCAL menu to be displayed. 

2. 

Press PREV or 
NEXT 

This selects a SEQUENCE. Up to 3 Sequences can be defined. A 
Sequence is a definition of zero/span calibrations along with timing 
information. 

3. 

Select MODE, then 
PREV or NEXT 

MODE allows you to select the order of zero, low-span or high-span 
that will be performed, MODES are listed in Table 6-3. Use PREV - 
NEXT to scroll the list of choices, then press ENTR to select. To 
disable a sequence, select DISABLE from the menu.  

4. 

Press SET 

This menu sets up several timers and selects calibration or calibration 
check. 

1.  TIMER ENABLE – If set to ON, the defined sequence will 

execute. If set to OFF, the sequence will remain in memory, but 
will not execute. 

2.  START DATE - calendar date to start sequence dd-mmm-yy, day-

month-year format.  

3.  START TIME - time of day sequence will start. hh-mm, hours-

minutes in 24 hr format.  

4.  DELTA DAYS and DELTA HOURS:MIN is the time between 

each activation of the sequence. By setting the Delta Hours 
variable to be other than an exact number of days, the sequence 
can move ahead or be delayed each time it is run. For example, by 
setting DELTA DAYS = 1 and DELTA HOURS = 1:00, the 
sequence will execute 1 hour later each day. To set it to move back 
½ hour each day, DELTA DAYS = 0, DELTA HOURS = 23:30. 

5.  DURATION -Amount of time for each zero/span point. 
6.  CALIBRATE – If set to ON, will calibrate(adjust slope and 

offset). If OFF will check, but not change calibration.
