The last key, [
REQUIRE ACKNOWLEDGE
] will cause the audible alarm to beep until the
blinking [
ALARM RESET
] key is pressed. If the [
REQUIRE ACKNOWLEDGE
] key is yellow
(disabled), then the alarm will shut off by itself at the start of the next sample. The
[
BEEP ON ALARM
] key must be enabled, though, before there will be an audible alarm.
2.2.3 How to set an alarm level for flow
To set alarm levels for percent flow, press the [
MORE
] key on the lower right corner
of the alarms menu screen to take you to the flow alarm menu screen. Flow alarm
limits are entered in percent such that a low flow alarm setting of 90% would set an
alarm 10% below nominal.
If there is a flow alarm during the sample the data can be discarded by selecting
[
ENABLED
] or [
DISABLED
] on this screen. If [
ENABLED
] the unit will discard any sample
during which a flow alarm occurs. If the sample is discarded, it will not print,
transmit or be saved in the stored data memory when it is completed. The
occurrence of the alarm will be printed if the printer is enabled. The printout will
indicate that the sample has been discarded if that choice is enabled. Sampling will
continue.
A factory set flow alarm occurs if the flow drops below 80% for five seconds. In this
case sampling stops and a message appears stating that sampling has been halted
due to low flow rate.

NOTE: If setting a flow alarm, have at least 5 seconds initial
delay. A false alarm may occur if the sample period
begins before the flow reading has reached its full
level.
2.2.4 How to create and use a stored program
The CI-154 allows you to configure parameters and location IDs for a given sample
area and save them under a named program, so that the parameters can be easily
recalled every time you have to sample that area, or areas, with similar
requirements. Up to thirty separate programs can be saved in the internal memory.
The first step is to enter the various parameters, such as sample volume and delay
times, and any alarm settings. Once all the parameters have been set for sampling
the area, press the [
SAVE SETTINGS
] key on the set-up menu screen. Move the
highlight to the point in the list where you want to insert the new program name,
then press the [
INSERT
] key. This will take you to a screen with a keyboard where
you can type in the name (up to 16 alphanumeric characters) that you want to give
to this particular group of set-up parameters. Once the name has been entered,
press [
EXIT
] and the new program will appear on the list of programs. The new name
will be inserted before the cursor location. If no names have been entered, you can
leave the cursor on
NO CHANGE
, but once there is at least one name on the list, the
cursor must be moved past the
NO CHANGE
option. Once thirty programs have been
entered, no new programs can be entered without first deleting a program.
If you need to change one or more sampling parameters for a given program,
change the settings, as needed, then press [
SAVE SETTINGS
], highlight the program
whose settings you are changing, then press [
EXIT
]. You will be prompted to save
the settings. Press the [
YES
] key to accept the changes that you made to the
program.
