Casella CEL Apex personal sampling pump - Manual (Page 2)

Select Set Flow then set the flow to less than 0.8 litre/min to
activate the mode.
In Bag Mode, the display shows BAG . The speed of the pump
motor is fixed and the display shows only percentage flow,
with no volume or time information.
Once the pump has started, or may be used to change
the flow rate to a different percentage.
Fixed Duration Sampling (DUR)
The duration of a sample can be selected from the instrument
keypad. On the Apex Pro it can also be selected via Pump
Manager software.
This mode allows the pump to sample for a fixed period and
switch off automatically when the period has ended. This is
useful when a stated volume of air must be sampled over a
long period.
In Hold Mode press or several times until DUR blinks
on the display. Press to select.
The programmed duration blinks to indicate it can be changed
by and . Run durations between 3 minutes and 1 hour
can be set in 1-minute steps, and durations between 1 and 25
hours in 10-minute steps.
Press to accept a duration and start sampling.
In addition to the symbol, the display shows PROG. to
indicate that a program is active. While the program is running,
the display cycles through current sample time, volume
sampled, air temperature, and programmed duration.
Once completed, the pump will switch off and the display
show and a PROGEnd message.
Press any key to return the pump to Hold Mode.
Locking The Keypad
The keypad may be partially or fully locked to prevent
unauthorised tampering with instrument settings.
Press three times within 2 seconds to activate Partial Lock
Mode at any time. The symbol is displayed, the counters
and flow cannot be changed but the following options remain
available: start/stop sampling, switch the pump off, unlock
Partial Lock, and select Full Lock. (Press three times within
2 seconds to unlock.)
Only when the PUMP IS RUNNING, press three times
again within 2 seconds while in Partial Lock Mode to activate
Full Lock Mode. The symbol is displayed, the pump cannot
be switched off and the only option available is to release Full
Lock Mode by pressing three times within 2 seconds.
TWA Sampling (Apex Pro only)
This feature is available only when the Apex Pro Program
Mode has been enabled from within Configuration Mode.
This allows the pump to operate for a fixed percentage of a
specified sample time. The instrument calculates the required
on/off cycle automatically to spread the total exposure time
over the entire sample time (as shown).
In Hold Mode press or several times until TWA blinks
on the display. Press to select.
RUN is displayed and the sample time blinks to indicate that it
can be changed by and . Run times between 3 minutes
and 1 hour can be set in 1-minute steps, and times between 1
and 25 hours in 10-minute steps.
Press to accept a sample time.
EXP is displayed, and the exposure time blinks to show it can
be changed by and .
The available range is 2 minutes to 1-minute-less-than-the-run-
time, in 1-minute steps.
Press to accept an exposure time and start sampling. In
addition to the usual and symbols the display shows
PROG. to indicate that a program is active.
The pump exposure (on) times are fixed at 1 minute, and the
instrument calculates the necessary off-times to spread these 1
minute intervals throughout the sample time. While the
program is running, the display cycles through current
accumulated sample time, volume sampled, air temperature
and calculated TWA (as percentage of run time).
During off-times (pump not running) the and symbols
are displayed to show the instrument is paused.
Once the sample is completed, the pump will switch off and
the display show the symbol and a PROGEnd message.
Press any key to return to Hold Mode.
User Program Modes (Apex Pro only)
This feature is available only when the Apex Pro Program Mode
has been enabled from within Configuration Mode. For more
comprehensive information, please refer to the User Handbook.
This allows complex sampling schedules (created by the user in
Pump Manager PC software and downloaded via the infrared
link) to be run by the pump. The programs are stored in two
user program areas
Pr1 and Pr2 .
In Hold Mode, repeatedly press or until Pr1 or Pr2
blink. Press to select the program.
The various steps in the program can be viewed using and
. Press to accept the program and start it running.
In addition to the usual and symbols the display shows
PROG. to indicate that a program is active.
During off-times (when the motor is not operating) and
are displayed to show the unit is paused.
Once the run is completed, the display will show the
symbol and a PROGEnd message.
Press any key to return the pump to Hold Mode.
To terminate the program early, press and hold to show the
STOP option, keep pressed until the pump reverts to Hold
