Preparation
Please refer to warnings and operation section of
HB3294-02 before using I.S versions of Apex pumps.
The default settings used by the pump (such as menu language
and temperature units) can be specified from within the pump’s
Configuration Mode.

press and hold a moment to cancel a command, press
and hold down to switch OFF.
Scrolls up through options or increases a value, has a
hold-down to repeat function.
Scrolls down through options or decreases a value, has
a hold-down to repeat function.
Press to accept a value or option (for example start the
pump). Hold down to stop the pump.
Display Symbols
Halt - shows when pump is in Hold Mode, or blinks
when halt option available.
Run - shows when pump motor is running.
Flow - indicates real flow monitoring.
& together indicate that the pump is paused, but will
start again automatically, for example during TWA or
user prepared programs.

Indicators & Display Messages
Green LED Flashes when the motor is running.
Red LED Flashes when unable to maintain the required
flow due to restriction.
PROGEnd Displayed when the pump has successfully
completed a programmed sample.
BATTFAIL Warning that the voltage from the battery pack is
below minimum operating level.
SERV dUE Warning after 2500 hours of operation that the
instrument should be serviced.
Buzzer When activated sounds warnings and indicates
keystrokes.
Switch Instrument On / Off
To switch the instrument ON, press and hold until the
instrument display is activated. The display starts to test its
segments, shows the pump ID and finally the firmware version
number before entering Hold Mode.
On Apex Pro versions only, the-day-of-the-week and the time-
of-day are also displayed during the start up cycle.
If the display is too bright or dim, shows messages in an
unexpected language or unexpected measurement units, make
changes as described in the Configuration Mode section.
To switch OFF, press and hold . The display will show a
count down in seconds until the instrument switches off and
the screen becomes blank.
If is released before the countdown has finished, the
instrument returns to its previous mode.
Hold Mode
When the instrument is switched ON but the pump is not
operating, nor a program being executed, it is in Hold Mode
where the display cycles between:
TIME Accumulated sample time since the instrument was last
reset.
VOL Accumulated volume sampled since it was last reset.
TEMP Current air temperature.
Manual Reset (Clear Current Sample)
To clear any accumulated sample duration and volume, the
instrument must be in Hold Mode.
Press or sufficient times to make blink on the
display.
Press and hold until CLR and the countdown disappear, to
clear the accumulated values.
Set Flow (Single Point Calibration)
Attach a sampling head and flow tube or other flow-measuring
device to the pump’s inlet nozzle to measure the actual flow.
In Hold Mode, press or several times until FLOW SEt
blinks on the display. Press to select.
Use and to set the flow required at this calibration
point, then press to accept the setting. The pump will start.
A soon as CAL SEt is displayed, use and to adjust the
actual flow measured by the flow tube to match the set point,
then press to accept the value.
This calibration point will be saved and used by the pump in all
future samples made at this flow.
To return to Hold Mode without setting a new flow, press
and hold for a moment.
If the calibration is not completed within 30 seconds, the pump
will revert to Hold Mode automatically.
When basic settings are acceptable, proceed directly to the
Manual Sampling section, if not acceptable, go to Configuration
Mode.
Configuration Mode
This mode allows basic settings to be changed. It can be
activated only while switching the instrument on.
Press to switch on, then immediately hold both and
down. After a brief display test, the first configuration option is
displayed.
LANG Sets the display language (the currently set language
blinks).
Use or to change then press to accept.
TEMP Sets temperature display (current units blink).
Use or to change between Centigrade and
Fahrenheit, then press to accept.
VOL Sets volume display mode (current mode blinks).
Use or to change between Auto or m 3 .
Auto displays volumes below 1000 litres in litres, above
this the display changes to m
3 .
m 3 always displays volumes in m 3 .
BUZZEr Allows an audible alarm to be set.
Use or to change between:
OFF , no buzzer,
Err , any error sounds an alarm,
On , any error or key press sounds an alarm.
PROG Mode Determines whether the program features of an
Apex Pro are to be made available.
Use or to change between:
ON with the program features available,
OFF with the program features hidden.
Press to accept.
LIFE Is read-only and shows total run time for the pump.
This can be used to determine suitable maintenance
schedules for the instrument.
Press to move on.
LCD Sets LCD contrast (current level blinks).
Use to increase the value (make darker) and to
decrease it (make lighter).
Press to accept.
CAL SET Activates Calibration Mode, allowing the pump’s
calibrated range to be reset.
Use or to change between:
NO - do not recalibrate the pump, then press to
revert to Hold Mode,
Or,
YES - recalibrate the pump, press to enter
calibration Mode and proceed to Calibrating The Pump.
Manual Sampling
While in Hold Mode, press to start sampling and enter Run
Mode.
In Run Mode the display cycles between, current duration of
the sample, volume sampled, and air temperature.
To stop sampling while the pump is in Run Mode, press and
hold until the symbol stops blinking and disappears.
The instrument will save the accumulated duration and volume
sampled until manually reset.
Flow Restriction
If the input flow is restricted, both and the Red LED will
flash (and when activated the buzzer sound) to indicate a
problem. If the problem lasts for eight or more seconds, the
pump motor will switch itself off.
After one minute, the pump will switch on again in an attempt
to determine whether the problem has gone. If the problem
remains for another eight seconds, the pump will switch off
and remain off.
If the output flow is restricted, both and the Red LED will
flash (and when activated the buzzer sound) to indicate a
problem. If the problem lasts for three or more seconds, the
pump motor will switch itself off and remain off.
Normal operation cannot be resumed until the flow restriction
has been removed. When the restriction is removed, the pump
may start again automatically; if it does not, switch the Apex
unit OFF then ON again.
Use With Low Flow Adaptor
This enables the instrument to be used with sorbent tubes at
flows down to 5 millilitres/min.
Connect the inlet of an Apex unit to a flowmeter such as the
Dry Cal and calibrate the flow rate to 1.5 litre/min.
Stop the pump and disconnect the flowmeter.
Starting from the Apex inlet, connect the following: constant
pressure regulator, low flow adaptor, sorbent tube holder and a
low flow flowmeter such as the Dry Flow or Dry Cal.
Break both ends off a sorbent tube and put it in the holder with
the arrow pointing towards the pump.
Start the pump and adjust the flow to the required rate using
the screw on the side of the low flow adaptor.
Perform the measurements using a fresh sorbent tube.
Bag Mode
This allows the pump to fill a gas bag and stop automatically
when the bag is full. Connect the gas bag to the pump outlet.
