Weatherproof power supply/battery charger
Gel cell battery
PM2.5 sharp cut cyclone
TSP inlet (weather cap)
Airsis telemetry system
oPower cord
oSerial communication cable

Charging Batteries
Charge the batteries for at least 1 day before use.
E-Sampler –
oConnect the plug from the weatherproof power
supply/battery charger to the appropriate connector on
the bottom of the E-Sampler.
oConnect the power supply to line power. Charge the E-
Sampler power supply for at least 24 hours.
OR oCharge the gel cell battery with a plug-in charger for
12-volt gel cells.
Charge the telemetry system by plugging the power cord
from the system to line power.
SITING THE E-SAMPLER AND
TELEMETRY SYSTEM
The E-Sampler and its telemetry system should be placed in
an open area away from obstructions such as trees or
buildings, and away from external pollution sources (road
dust, industrial pollution, and so forth). The telemetry antenna
must have a clear view of the sky to transmit data.
SETUP IN THE FIELD
Remove the three pins from the tripod and unfold the legs
until they are fully extended. Replace the pins in the holes
in the leg flanges.
Attach the E-Sampler to the tripod by sliding the slot on the
back of the E-Sampler over the mounting tab on the tripod.
Attach the bottom of the E-Sampler to the tripod by sliding
the ¼-inch bolt through the bottom flange and through the
tripod. Hand tighten the nut on the bolt.
Attach the PM2.5 sharp cut cyclone to the inlet of the E-
Sampler.
Attach the TSP inlet (weather cap) to the PM2.5 sharp cut
cyclone.
Attach the power supply/battery charger to the tripod.
Attach the connector from the power supply to the bottom
of the E-Sampler.
Attach the telemetry system to the tripod, using the supplied
hardware.
Plug the communication cable from telemetry system to the
appropriate connector on the bottom of the E-Sampler.
Attach the power cord from the power supply and telemetry
system to the extension cord and plug in the extension cord
to line power.
OR if using the gel cell battery –
Inside the E-Sampler, remove the battery cover plate.
Connect the two-prong connector of the internal battery
cable to the E-Sampler circuit board.
Attach the RED (+) and BLACK (-) wires of the battery
cable to the battery terminals.
CHECKING SETTINGS ON THE E-SAMPLER
The MENU/SELECT, ESC, left, right, up, and down arrows
are used to traverse the screens on the E-Sampler. The blank
white buttons under the screen are used to save or exit
settings. Settings on the E-Sampler should have been set
already. The instrument stores these settings.
Verifying SETUP settings:
From the Main Screen:
Press the MENU/SELECT button.
Use the arrow buttons to move the cursor to SETUP. Press
MENU/SELECT.

Use the up and down arrow buttons to move the cursor to
the desired setting and press MENU/SELECT. Adjust the
following settings:
CLOCK – Set to GMT time
AVERAGE PERIOD – Set to 60 MIN.
CONCENTRATION –Set to AUTO; DAC to 1.0 V; K-FAC
to 1.00.
SAMPLING MODE – Set to CONTINUOUS.
ALARM CONTACT – Does not apply.
RH HEATER CONTROL – Set RH SETPOINT to 50%.
ZERO MODE – Set ZERO MODE to AUTO; ZERO
PERIOD to 24 HR.
SPAN MODE – Set SPAN MODE to AUTO; SPAN
PERIOD to 24 HR; RESTORE DEFAULT to
NO.
BAUD RATE – Set BAUD RATE to 9600.
STATION ID – Does not apply.
ENGR UNITS – Set to METRIC.
Press the ESC button twice to get to the main screen.
STARTING A RUN
From the main screen, press the white button under TURN
ON.
Press the white button under TURN ON.
The E-Sampler will go through a ZERO and SPAN check and
then begin to sample. After several minutes the screen will go
blank to conserve power. Press the ESC button to turn the
display back on.
STARTING THE SATELLITE TELEMETRY
SYSTEM AND VERIFYING COMMUNICATIONS
Open the telemetry system and turn the system on.
The left light will illuminate red.
The following diagram shows the various states of the
telemetry system and corresponds to the LED indicators
located inside the telemetry system. LED indicators verify
that the telemetry system has power, the modem is receiving
information from the E-Sampler, and the antenna on top of
the telemetry system is “seeing” satellites.
A. Modem initialized light is on.
B. Serial Data measurement Digital 0 from E-Sampler light is
on.
C. Serial Data measurement Digital 1 from E-Sampler light is
on.
D. Light is ON when satellite is in view and OFF between
satellite passes. (If this green LED light does not turn on
within 30 minutes, move the telemetry system to a higher
unobstructed position.)
STOPPING THE E-SAMPLER
To stop the E-Sampler, press the ESC button to turn the
display back on.
Press the white button under TURN OFF on the next two
screens.
TRANSFERRING DATA FROM THE E-SAMPLER
TO A LAPTOP USING HYPERTERMINAL
Disconnect the telemetry system serial communication cable
from the E-Sampler.
Connect the Met One serial communication cable to the
appropriate connector on the bottom of the E-Sampler and
to the serial connector on the laptop.
On the laptop, click the HyperTerminal icon. “Connected”
should display on the bottom of the screen.
On the top menu bar, click “Transfer>Capture Text.”
On the laptop, press the return key several times. The “>”
symbol should appear on the screen.
Press the number “2” button. Data should begin to scroll
across the screen.
When data stops scrolling, click on “Transfer > Capture
Text > Stop.”
Close the HyperTerminal program.
Remove the gel cell battery before
shipping or moving the E-Sampler.
