2.3.1 Preparation
1. Charge the battery according to Battery Mainte-
nance Instructions provided in this Manual.
2. Using a small Phillips-head screwdriver, back out
the holding screw of the anti-tamper cover plate to
expose the On/Off switch and the flow adjust
screw. (On the front of the pump.) On the left side
of the pump, back out the holding screw of the
anti-tamper cover around the display opening to

tons.
NOTE
The pump switches to an low-powered “sleep” mode
after 5 minutes of inactivity whenever the On/Off switch
is positioned in the Off position. This conserves the
battery charge.
3. If the On/Off switch is moved to the On position at
any time, the pump will begin to run and collect
data for a new sampling run of the last-selected
program (see Section 2.3.8).
Exception: If “CAL” is
showing on the display the pump is in calibration
mode and no data will be collected at this time.
2.3.2 Waking The Pump For “LAST” Run Data
Readout
1. With the On/Off switch still Off, and using the
pointed instrument, press the MODE/HOLD button
to wake the pump up from its “sleep” state.
2. The “LAST” message will appear on the display,
followed by a program number display, “Px” (“x”
may be the letter C or 1 through 6), which is then
followed by the presentation of the run time data
obtained by the last sampling run. Also on the dis-
play in the lower right hand corner is a small digit
which indicates the percentage of time in which
the last sampling run was made outside of the
±
5%
(fault) variation in the flow rate, with the maximum
presentation of up to 9%. Across the lower portion
of the display may be presented one or more icons.
If the “CAL” display appears instead at this time,
press the MODE/HOLD button four more times to
present the “LAST” run data.
Record the “LAST” run data at this time.
NOTE
If the On/Off switch is set to On at this point to begin a new
sampling run, the “LAST” run data will replace the “Old”
run data, which will be lost at that time, as the last run
data is cleared for the new sampling run data. However,
you may retrieve the “Old” run data later by pressing the
MODE/HOLD button (with the On/Off switch in the Off
position) until the “Old” data are displayed.
3. After 5 minutes free of any button depression, the
display will blank as the sampler returns to the
“sleep” mode. Return to Step 1 to reactivate the
unit.
