Pump Operation - Industrial Scientific 17154524-1 Bedienungsanleitung

Pump operation

1. Power on the instrument.
Attach the sample tubing
(shown) or sampling wand
to the pump inlet's nipple.
Recommended Practice: When sampling with a motorized pump and tubing, ISC recommends the "2 Plus 2 Sampling Rule". This is a guideline for
calculating the time needed for the air sample to reach the instrument and produce readings for any gases present that are detectable by the installed
sensors. Before noting the instrument readings, allow for a base sampling time of 2 minutes plus an additional 2 seconds per foot of tubing. For example, if
the sample tubing is 20' (6.096 m) in length, allow a total time of 2 minutes and 40 seconds (20 x 2) before noting the instrument readings.
*Operation at room temperature.
NOTE: If the pump does not successfully power on, check the battery's level of charge; for possible fault indicators, see the "Alarms" section.
2. Power on the pump: press and hold the pump's power button
for two seconds. During the power-on process, the audible
alarm and each LED will turn on, then off.
Check the pump's battery status indicator.
• Solid green indicates the battery's charge level is between
50% and 100%.
• Solid amber indicates the battery's charge level is at 50%
or less.
• Continuous blinking amber and an audible beep every
15 seconds indicate a critically low battery: the battery's
remaining charge will operate* the pump for less than one
hour.
To power off the pump, press and hold the power button for
five seconds. The audible alarm sounds five times as the pump
powers off.
Setup, Operation, and Service
—
3. Before taking an air
sample, force a pump fault
condition: place a finger
at the end of the tubing to
block the flow of air.
If the pump fault occurs,
remove the finger from the
tubing; the pump should
resume normal operation
within approximately 10
seconds.
If no pump fault occurs or if
the unit stays in pump fault,
see the "Alarms" section for
possible causes and
recommended actions.
