High Flow Operation
The S
IDE
P
AK
™
SP330 and SP350 are operated in a continuous flow mode
when used for high flow sampling with filter cassettes and other high flow
sampling devices (i.e., cyclones, impactors, impingers, bubblers, IOM
Samplers, etc). The S
IDE
P
AK
™
SP330 and SP350 have flow rate ranges
from 1000 cc/min. to 3000 cc/min. and 1000 cc/min. to 4000 cc/min.,
respectively.
Calibrating a S
IDE
P
AK
™
SP330/SP350
When calibrating a S
IDE
P
AK
™
SP330 or a SP350 for low or high flow
sampling the following generic procedure may be used.
1. Start up the S
IDE
P
AK
™
SP330 or SP350 and let it warm up for 2
minutes prior to starting this calibration procedure.
2. Configure your sample pump for low or high flow sampling (i.e., attach
a LFA for low flow/constant pressure operation mode, etc.). Refer to
High and Low Flow Operation sections found in this chapter.
3. Attach the outlet of the sample media tubing to the inlet of the sample
pump.
4. Connect the outlet of the external calibrator to the inlet of the sample
media.
5. Turn the external calibrator on.
6. Follow the Flow Setpoint and/or the Low Flow Adapter Procedure
found in this chapter to setup and enter the proper keypad commands
necessary to complete the calibration procedure.
Flow Blocked Error
When the flow is blocked, the pump will continue to try to maintain the flow
rate for 20 seconds, during which time the words
FLOW BLOCKED will
alternate with FLOW MODE , the LED will flash twice per second and will
beep once per second. If the flow rate is not regained after the 20-second
period, the pump will shut off for 40 seconds, at the end of which time it will
turn the pump back on and retry to get the desired flow rate. This process
will repeat for ten more cycles, at the end of which the pump will remain off
and the LCD will alternate between
FLOW BLOCKED PUMP SHUTOFF
and READY MODE ENTER = START . If the
↵
key is pressed, the
process will begin again. If at any time during the pump restart sequence the
flow block condition is removed, the flow will resume. If a flow block
occurs again the process will start at the beginning.
