Normal Operation
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. I

The instrument will display the Serial Number and Cell
Number, followed by the manufactured date.
Serial # 0000001

Maintenance
The electrochemical cells of the CAL 2000 LT require
periodic maintenance to provide optimum performance. It is
recomended that the electrolyte solution be replaced on an
annual basis.
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.
The electrolyte in the electrochemical cells can also dehy-
drate over time in dryer climates. A low electrolyte level will
ultimately result in a "Cell Failure" warning. Since only water
is evaporated, and the electrolyte salts are remaining in
solution, it is only necessary to replenish the electrolyte with
distilled or de-ionized water. Ordinary tap water (as well as
many bottled waters) should not be used as it contains
chemicals and minerals that could contaminate the cell.
Replenishing the cell with water is similar in procedure to
replacing the electrolyte shown above, but the remaining
electrolyte is not removed before the replenishment water is
added.
