Activates Calibration Mode, which allows the entire calibration for the pump to be reset,
based on a two point calibration.
The instrument will have been accurately calibrated at the factory prior to delivery.
Therefore it is recommended that this operation be performed only as part of a routine
service or when specific fine tuning is required to ensure that any selected flow rate will
be as close to the true flow as possible.
NO Do not recalibrate the pump.
YES Recalibrate the pump.
For information about recalibrating the whole range of an Apex or Apex Pro unit, refer to Chapter 5.

3. MANUAL OPERATION
3.1 Run Mode
1. To start sampling and enter Run Mode, press while in Hold Mode.
In Run Mode the display will cycle between, current duration of the sample, volume sampled, and
internal air temperature.
2. To stop sampling while in Run Mode, press and hold until the symbol stops blinking and
disappears.
The instrument will display and save the accumulated duration and sample values until manually
reset.
Clearing values by a manual reset to close the run sample upon completion of an event ensures
that all downloaded data will be conveniently arranged to correspond with the sample result.
3.2 Flow Restriction
If the input flow becomes restricted, both and the Red LED will flash to indicate a problem and if
enabled, the buzzer will sound. When 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. When the problem remains for a further eight seconds, the pump will switch OFF and
remain off with the instrument still ON and displayed.
If the output flow is restricted, both and the Red LED will flash to indicate a problem and if enabled,
