II.

Normal Operation: Diffusion Mode

To start the generator, press and hold the POWER switch,

located in the middle left front of the instrument, until the

display reads A. C. D., approximately three (3) seconds.

Release the switch immediately thereafter.

The instrument will sequence through several screens as

follows:

A. C. D. VI

Please Note: If you would like to change the language of

the menus, see section IV. Menu Options: Foreign

Language Option, for instructions.

The instrument will display the Serial Number and Cell

Number, followed by the manufactured date.

Serial # 0000001

Cell # 000001

Manufactured

01 Jan 2000

Calibration Date

Maintenance

The electrochemical cells of the CAL 2000 require periodic

maintenance to provide optimum performance. It is

recomended that the electrolyte solution be replaced on an

annual basis for most gases generated by the CAL 2000.

The exception to this is the ClO2 electrolyte. Please refer to

the instructions enclosed with every chlorine dioxide cell or

replacement electrolyte pack.

If the instrument is returned with the cell on an annual basis

to maintain NIST certification, the electrolyte will be replaced

by the factory.

The following steps should be taken to replace electrolyte.

........a. Remove cell as described in section I. General

Description: Cell Installation and Removal.

........b. Unscrew solid fill plugs on reservoir and

remove liquid.

........c. Use syringe (provided with electrolyte) to add

liquid to within 1/8 inch from the bottom of fill hole.

Warning: Do not over-fill reservoir. Trapped air must be

allowed to escape through vent plug as fill screw is

replaced. Contact the factory for more information.

........d. Replace fill plugs.

Caution

Both the electrochemical cell and the alkaline batteries used

in the CAL 2000 instrument contain corrosive chemicals. In

addition, depending on the type of cell being used, the gas

being generated can be corrosive. The design of the

instrument takes this into consideration, and the 300

second purge cycle allows the corrosive gases to be swept

out of the instrument. It is important not to remove the

generating cell before this purge cycle is completed. While it

is not expected that the chemicals in the cell or alkaline

batteries will leak during normal operation, it is recom-

mended that both the generating cell and the alkaline

batteries be removed from the instrument if it is being stored

for periods longer than one week between use.
