Part II: 5-3

WARNING: THE SENSORS USED IN THE MODELS 3010 OXY-

GEN ANALYZERS USE ELECTROLYTES WHICH
CONTAIN TOXIC SUBSTANCES, MAINLY LEAD AND
POTASSIUM HYDROXIDE, THAT CAN BE HARMFUL
IF TOUCHED, SWALLOWED, OR INHALED. AVOID
CONTACT WITH ANY FLUID OR POWDER IN OR
AROUND THE UNIT. WHAT MAY APPEAR TO BE
PLAIN WATER COULD CONTAIN ONE OF THESE
TOXIC SUBSTANCES. IN CASE OF EYE CONTACT,
IMMEDIATELY FLUSH EYES WITH WATER FOR AT
LEAST 15 MINUTES. CALL PHYSICIAN. (SEE AP-
PENDIX, MATERIAL SAFETY DATA SHEET.)

CAUTION:

Do not disturb the integrity of the cell package
until the cell is to actually be used. If the cell pack-
age is punctured and air is permitted to enter, the
cell will require an excessively long time to reach
zero after installation (possibly several hours).

5.2.2 When to Replace a Cell

If the 3010P analysis readings begin to drift downward uncharacteris-

tically, try recalibration. If recalibration raises the readings for a short time
only, suspect the cell, but first check for leaks downstream from the cell
where gases may be leaking into the system
.

You can check the output of the cell itself by going to the

System

function, selecting

More, and pressing

Enter

. The cell output reading will

be on the second line of the display.

Version Self—Test

Cell Output: ### µA

The “good” cell output range depends on the class of cell your ana-

lyzer is using. The B-1 cell is standard in the 3010P, but others can be
specified.

Check Specific Model Information in the Front Matter in this

manual for the class of cell you purchased. Then check Table 5-1, the
cell index table below, and do the simple calculation. If the resulting value
is below the

Cell Output reading, replace the cell.

To find out if your cell is too weak:

1. Flow span gas through the analyzer, and allow time to purge.
