CI-90A User’s Manual 

Page 16 

 

To enable Secure Setup, the user must first enter the setup menu, if not already there, and then 

use the up/down arrows as necessary to scroll to the SECURE SETUP field.  The user can 
toggle this option on or off (Y or N) by using the left/right arrows. 

2.2.7  Secure sample? 

The Secure Sample feature of the CI-90A allows the user to essentially lock the keyboard 

during a sample. Only the DSPL key will function and allow changing the information displayed 
on the main screen third line. This prevents the sample from being stopped prior to its 
completion, and prevents user access to any of the CI-90A’s settings.  When in Secure Sample 
mode the user can access all features of the CI-90A until the [

START

] key is pressed. After this, 

only the DSPL key functions, preventing the user from changing the site ID, the user ID, the 
unit ID, or any of the parameters available under the setup menu.  The user, of course, can still 
stop the sample by pressing [POWER] to turn the unit off.  

 

To enable Secure Sample, the user must first enter the setup menu, if not already there, then 

use the up/down arrows as necessary to scroll to the SECURE SAMPLE field. The user can 
toggle this option on or off (Y or N) by using the left/right arrows. 

2.2.8  Date format 

The Date Format feature of the CI-90A allows the user to select either an MM/DD/YY or 

DD/MM/YY format for the date. All displays or printouts will be formatted according to the 
option selected. 

 

To select a date format, the user must first enter the setup menu, if not already there, and then 

use the up/down arrows as necessary to scroll to the DATE FORMAT field.  The user can 
toggle this option between MM/DD/YY or DD/MM/YY by using the left/right arrows. 

2.2.9  Date/time 

The CI-90A allows the user to set the current date and time. Once set, the CI-90A’s internal 

real time clock will continue to keep the date and time. The real time clock is powered off the 
internal battery, but a backup capacitor provides enough power (over 30 minutes) to allow the 
battery to be changed without losing the date/time setting.
