Set Flow Rate
1.
From the
Main Menu
, select
Flow Set
using the
NAV
keys.
2.
Press the
INC/DEC
keys to set desired flow rate, then press the
POWER/ENTER
key to enter the desired flow rate.
Note:
Flow range select must be in Lo if the flow is less than 445 cc/min and in
Hi for rates from 450 to 5100 cc/min. The flow range select is on the right side
of the case and can be switched between Lo and Hi with a 2mm (5/64") hex
wrench supplied with the pump. Indication of Lo or Hi selection displays in the
middle of the lower display status line.
Flow Calibration
1.
Connect the pump to an air flow calibrator per the
calibrator manufacturers’ recommendations. A
representative sample media must be connected at
the inlet to the pump to establish proper load
conditions. A calibration panel may be substituted
for the sample media, set for a pressure drop of 4
inches of water.
2.
While pump displays the
Main Menu
use the
NAV
keys to select
Calibrate,
then
Press the
POWER/ENTER
key.
3.
Display shows the set flow rate and the pump
begins to run in the calibration mode.
4.
Use the
INC/DEC
keys to adjust the flow rate
displayed on the pump until matching the flow rate
measured by the calibration device.
5.
Press the
POWER/ENTER
key to set calibration.
6.
Press
ESC
key to return to
Main Menu
.
Field Calibration Note:
Display calibration procedures above make internal pump adjustments and improve the accuracy of the flow display. This
does not replace field calibration as described by OSHA and NIOSH. Conduct flow verification using a Primary Calibrator
prior to each field sample. Field calibration procedures are referenced in the
NIOSH Manual of Analytical Methods
at
www.cdc.gov/niosh and the
OSHA Technical Manual
at www.osha.gov.
Starting the Sample Run
1.
With pump displaying the
Main Menu
use the
NAV
keys to select
