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,

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

several times until

DUR

blinks

on the display. Press

to select.

The programmed duration blinks to indicate it can be changed

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 any key to return the pump to Hold Mode.

Locking The Keypad

The keypad may be partially or fully locked to prevent

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

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

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.
