Sampling
• Before use, allow pump to equilibrate after moving it from
one temperature extreme to another.
• Use of any device or battery pack other than P85004 and
P84002 to power the pump voids the UL Listing for intrinsic
safety.
• Charge pump battery completely before calibration and
sampling.
1. Calibrate pump fl ow rate (see Setting Flow Rate and Calibration).
2. Replace representative sampling media with new unexposed media.
3. To start a continuous or timed sample run, press []. Record start time and
other pertinent information.
• Sampling will start automatically if a run delay is set and initiated. Sampling
will stop automatically if a timed run is set and initiated.
• For automatic start and stop, set and initiate both a run delay and a timed run.
• For multiple-tube sampling, seal unused holder ports with unopened tubes.
4. Sample for the time specifi ed in the method used. Accumulated run time will
display on the LCD.
5. To stop a sample run, press []. This places the pump in
Hold. Record stop time and other pertinent information.
a. To resume sample run without clearing accumulated
run time, press [].
b. To clear accumulated run time, place pump in Hold, press  to enter
user setup functions, and press [] when CLr displays.
When using impingers, place a trap between the pump and the
impinger to protect the pump from harmful liquids or vapors. Failure
to use the impinger trap voids any warranty.
Flow Fault
If the pump is unable to compensate for longer than 15 seconds
due to excessive back pressure, the pump enters fl ow fault.
During fl ow fault, the fault icon displays on the display and
fl ashes during the length of the fault, the pump enters Hold
mode, and the accumulated run time display is retained. The
pump will restart in 15 seconds and try to continue sampling.
If the fl ow remains restricted, the pump will return to fl ow
fault. Auto-restart is attempted every 15 seconds up to 5 times.
Flow fault time is not added to accumulated run time.
To clear a fl ow fault and the fl ow fault icon, determine the cause of the fault, remedy
the fault cause, and press
[] to remove the icon from the LCD and restart the pump.
