CI-90A User’s Manual Firmware Revision History Revision 1.00 – May 26, 2005 Initial Release Revision 2.00 – January 29, 2008 Introduction of Sample Volume linked to Site ID. Revision 2.05 – October 8, 2008 Added automatic retry for printer errors.
Service by qualified personnel only. 1.2 Notes 1.2.1 Notice The CI-90A should never be operated with the transit lid installed. This may result in damage to the blower or other internal components. 1.2.2 Battery life Batteries offer portability, but all batteries have limited life. The choice of Nickel...
1.3.5 Storage If the CI-90A is to be stored for three months or longer without use, the battery should be disconnected to prevent damage to the battery from a deep discharge. To gain access to the battery, unscrew the two thumbscrews on the battery cover on the bottom of the unit.
CI-90A User’s Manual 1.3.6 Packing for shipment The packing container used for shipping the CI-90A has been tested according to the standards of the National Safe Transit Association. For this reason, it is recommended that the original packing container be saved for reuse if it has no obvious damage. The packing container consists of an outer double-walled cardboard box, two foam inserts, and an internal cardboard box used to hold accessories.
The CI-90A has menu options that allow the user to set up a UNIT ID name to identify the CI-90A used, a USER ID name to identify the user who took the sample, and a SITE (LOCATION) ID to identify where the sample was taken.

CI-90A User’s Manual observed approaches the number of perforations, the greater the undercount. The easiest way to correct the observed values into Probable Statistical Totals is to use the table in the appendix. Look up the observed value in column A, and find the Probable Total in the adjacent column B to the right.
CI-90A User’s Manual Section 2: Operation 2.1 Basic operation of the CI-90A 2.1.1 How to take a sample Before taking a sample, first make sure the aluminum transit cover is removed. This will prevent possible damage to the internal blower or other electronics.
EXIT 2.2.1 Sample volume The CI-90A has a number of preset sample volumes from which the user can choose. The minimum sample volume is 5 liters, which equates to a 3 second long sample time. The maximum sample volume is 1100 liters, which is 1.1 cubic meters and takes 11 minutes to complete.
The CI-90A will start the pump 2 seconds before the end of the sample delay to get the flow up to speed for the start of the actual sample. The CI-90A has a range of sample delays from which the user can choose.
The user can opt to have 0, 1, 2, or 3 labels printed after the sample. If the CI-90A should run out of paper during the printing of a label, the user can add more label paper and reprint the particular label.
(ERRLBS) of labels with Sample Status marked INVALID will be printed. Furthermore, the red alarm LED will continue flashing. After the user has recorded any relevant information, the CI-90A must be turned off and then back on to resume normal operation. ENABLE FLOW ALARM? Y...
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.
2.3.1 Creating an ID The CI-90A User ID’s can be assigned a 1 to 9 character identification which will appear on all label printouts. The operator can enter up to 10 ID names. To create a User ID, press [...
2.4.1 Creating an ID The CI-90A location (Site) ID’s can be assigned a 1 to 15 character identification which will appear on all label printouts. The user can enter up to 100 ID names. To create a Site ID, press ] from the main screen and observe the Site screen appears.

The loose end of the label roll then needs to be hand-fed forward into the printer. This must be done with the CI-90A powered on so that the user can press the [TOF] button then feed the labels into the printer. The printer is equipped with an optical sensor that detects when paper is being loaded.
CI-90A User’s Manual 2.6.4 Print options at the end of a sample At the end of a sample a menu screen will appear which provides the user with some print related options. The menu screen is illustrated below. SAMPLE COMPLETE...
CI-90A User’s Manual SAMPLE COMPLETE PRINT EXTRA LABEL? FEED If you would like to print another label for your last sample you can by pressing the [YES] button. Note that pressing the [YES] button will only print one label if you want more just press [YES] again until you have the desired amount of labels.

Auxiliary connections 3.1 RS-232 interface The CI-90A has an RS-232 interface that allows the CI-90A to communicate with the serial port of a PC. There are two commands that are primarily used for maintenance, and two others that provide the ability to rapidly enter Site and User ID’s into the unit. The Site and User ID names are created in the separately purchased program named CI-9x Loader (see next page), then downloaded serially into the CI-90.
ID’s are sent, and it routinely does it in about half the timer duration. When the k command is received the CI-90A responds by first starting a 4 second timer, then storing the next 90 characters it receives into non-volatile memory and setting the current user ID to the blank (00).
PC, the site and user ID’s are entered into the program’s site and user lists, and then the lists are separately downloaded into the CI-90A (the 90A must be on and not sampling). The list of site and user ID’s can also be saved as a named file for use at a later time. For detailed instructions on how to use CI-9x Loader, please consult the manual that comes with the software.
4.2 Tripod 4.2.1 Recommended Tripod / Tripod head The CI-90A microbial sampler has two locations where a tripod can be attached as shown earlier on page 7. CLiMET Instruments recommends that the Manfrotto #3001N basic tripod without head and the Manfrotto #488RC2 midi ball head with RC2 rapid connect system be used.
5.1.2 Long term storage If the CI-90A is to be stored for three months or longer without use, the battery should be disconnected to prevent damage to the battery from a deep discharge. To gain access to the battery, unscrew the two thumbscrews on the battery door.
The purpose of the calibration is to establish that the unit is in tolerance, and that sample volume is therefore accurate. The accuracy and consistency of your CI-90A can be degraded by unqualified and marginally experienced calibration services. To insure that the flow rate of the instrument is maintained to factory specifications, you may ship your unit to either our Eastern or Western service facility, or arrange for on-site service.
CI-90A User’s Manual Appendix — Feller Correction There is a statistical analysis that corrects the observation to a probable statistical total. This compensates for the fact that the probability of a colony forming unit (CFU) passing through a given perforation increases with the actual concentration of microbes per cubic meter.
