•Move from one field to another by pressing the arrow keys.

•Change a setting in a field by typing a number. Press ↵ to accept the new setting.

Note

For critical sampling applications, consider replacing the suc- tion line, pump tube, and discharge tube. Replacement elimi- nates the possibility of any cross contamination from previous sampling sites.

When you select OTHER FUNCTIONS from the main menu, and then select Maintenance, the following screen will be displayed:

SET CLOCK

PUMP TUBE ALARM

INTERNAL BATTERY

DIAGNOSTICS

Using these options, you can set the sampler’s time and date, set the number of pump counts for the pump tube warning, reset the battery warning for the internal battery, and run a set of diag- nostic tests for troubleshooting purposes.

Teledyne Isco ships samplers from the factory with the clocks set to the correct Central Standard Time. Reset the clock when installing the sampler in a different time zone, for daylight savings time, or when needed.

When setting the clock and calendar, use a 24-hour clock for times and the day-month-year format for dates. The illustration at the left shows blanks for each position that accepts an entry. The positions are called fields. When this screen appears on your sampler, the fields will contain the sampler’s current settings for the time and date.

•To move from one field to another without changing the setting, press the arrow keys. Use this technique when you want to change only one or two settings.

•Change the setting by typing a new number. Press ↵ to accept the new setting.

For example, to enter 2:00 p.m. (2:00 p.m is 14:00 on a 24-hour clock), type 14. Press ↵. Next, type 0 (zero) for the minutes, and press ↵. To enter a date, such as January 22, 2001, type: 22 ↵ 01 ↵ 01 ↵ .
