5.12Alarm High

5.12.1The instrument is fitted with a relay, which is set to activate on both high and low alarm conditions. The deadband is factory set. To set the ALARM HIGH proceed as follows.

a)Enter the menu and press CALL until ALARM HIGH is indicated. With the arrow buttons make the display read the desired alarm value. Press ENTER. The display will flash until ENTER is pressed again to confirm the entry.

b)Press RUN to place the instrument on line, or press CALL, for another menu selection.

5.13Alarm Low

5.13.1a) Press CALL until ALARM LOW is indicated. With the arrows make the meter read the desired value. Press ENTER. The display will flash until ENTER is pressed a second time to confirm entry.

b)Press RUN to place the instrument on line, or press CALL, for another menu selection.

NOTE: A low alarm point higher than the high alarm point is an invalid entry, which is indicated by the LED flashing when you return to RUN. To correct, return to the menu and reset the alarm points.

6.0OPERATING HINTS

6.1Cell Care

6.1.1If the sensor membrane is exposed to the atmosphere for more than 24 hours, the electrolyte inside the membrane can dry out. If this occurs, the cartridge will need to be replaced. To avoid membrane dry-out, place the sensor in a container of clean drinking water until it can be reinstalled into the aeration basin.

6.1.2Sensor cartridges can be stored for up to 5 years if the seal on its storage container is not broken and the temperature is between 70°F and 80°F with 50 to 80% humidity. Do not store sensor cartridges at temperatures below freezing point (32°F). The electrolyte solution will crystallize at 25-30°F.

6.1.3Cleaning the sensor membrane before each calibration is recommended. Use soft cloth and mild soap solution to remove material from the membrane. When cleaning, take care to avoid puncturing the sensor membrane. Should this occur, the complete sensor cartridge must be replaced.

6.2Calibration

6.2.1Depending on the application, system calibration should be performed periodically to maintain measurement accuracy. Frequent checks are suggested until the operational history indicates the optimum period between checks.
