RESET PUMP COUNTER?
YES NO
__00000 PUMP COUNTS
TO WARNING
To set the Tubing Life reminder:
1. Select the TUBING LIFE option and press Enter.
2. The sampler displays the current pump count. The display
automatically advances in four seconds or press Enter to
continue.
3. If you have replaced the pump tube, use the Next and
Previous arrows to select YES, then press Enter.
Otherwise, select NO.
4. Enter an interval using the Number buttons and press
Enter. (The default value is "5.")
The sampler counts pump revolutions in both the forward and
reverse cycles with a resettable counter. When the counter
reaches the default of 1,000,000 counts, the sampler displays an
alert message, "WARNING! CHANGE PUMP TUBE." After
replacing the pump tube (see section 5.1.2), reset the count to
zero so the sampler can begin tallying the pump counts for the
new tube.
Note
Opening the pump housing and replacing the pump tube will
not reset the counter.
The default count of 1,000,000 represents the average interval at
which the pump tube should be inspected. Because liquid
properties and site conditions affect the life of the pump tube,
you can change this interval to better suit your application. If a
pump tube inspection (section 5.1.1) at 1,000,000 counts reveals
little or no wear, this value can be increased to avoid needless
replacements. Conversely, if an inspection reveals significant
wear at 1,000,000 counts, this value should be reduced to prevent
a pump tube failure. Pump tubes wear out sooner when the
sampled liquid contains a high percentage of suspended or
abrasive solids. Pump tubes typically last 1,000,000 counts when
pumping relatively clean liquids at normal temperatures.
Note
The importance of regular tubing replacement cannot be
overstated. The key is to replace the tube before failure, not
after. When a pump tube ruptures, grit and other abrasive
debris can enter the pump housing. Over time, this abrasive
material may degrade the sample collection performance.
Failure to maintain the pump tube may result in permanent
damage to the sampler. Check the condition of the pump tube
regularly and if the tube shows signs of fatigue or wear,
replace it immediately. A properly maintained sampler will
provide years of reliable service that is expected of a Teledyne
Isco Sampler.
