INTRODUCTION
• COMPONENTS
See Figure 1.1
(1) Filter Housing Assembly (Inlet Port)
(2) Internal/External Vent Control
Use a flat-head screwdriver to adjust the internal/
external vent. The
open circle
position will vent
the pump discharge external to the sampler case
(recommended for moist or corrosive sampling
environments). The
closed circle
will vent
internally (recommended for dust laden
environments).
(3) Belt Clip
(4) Battery Charging Jack (with cover)
(5) 4-button Keypad
(6) Operation LED (Green). Flashes when the pump
is functioning normally.
(7) Liquid Crystal Display (LCD)
(7.1) Ready Mode display alternately shows the
Set Flow Rate, Sample Time, and Total
Volume Sampled. Sampling display
alternately shows the Live Flow, Sample
Time, and Total Volume Sampled.
Also displays “FLO,” “CAL,” “Clr” during
those operations.
(7.2)
VOL & L
. Shows total volume sampled
(liters).
(7.3)
MIN
. Elapsed time during sampling.
(7.4)
CC/MIN
. Displays set flow rate (Ready
Mode) or live flow rate (Sampling Mode).
(7.5)
SET
. Appears during Set Flow Rate Mode
and Pump Calibration Mode.
(7.6)
FAULT.
Appears when pump cannot
maintain flow within
±
5%.
After fault shutdown pump attempts to
restart every 3 minutes for next hour.
FAULT
appears when pump is initially
turned on, but disappears when pump
reaches preset flow rate.
(7.7)
HOLD
. If, after 30–35 seconds, fault cannot
be corrected, pump stops and
HOLD
appears
(7.7)
HRS
. Shows number of run hours since last
calibration. Pump display must be
calibrated every 200 run hours or every 30
days.
(7.8) Always displayed and is valid 2 minutes
after start-up.
3 bars = High charge
2 bars = Medium charge
1 bar = Low charge
NOTE
The Gilian 3500 automatically calculates the total air
volume sampled using the following formula:
Total Air Volume (Liters) =
Air Flow Rate (cc/min) x Sample Time (minutes)
1000 cc/Liter
