Battery Operation

Installing the Battery Pack

To enhance battery life, SKC ships battery packs separate from the pump. Once

installed, completely charge battery pack before operating pump.

1. Carefully align the ba ery jack on the ba ery pack with the ba ery ter-
minal on the bo om of the pump base plate and push the ba ery pack
into place.

2. Insert and tighten two security screws
provided.

3. Charge ba ery completely before operating
pump (see Charging the Ba ery Pack).

Charging the Battery Pack

Ensure the pump is not running. Do not operate pump while charger is
a ached. To charge the ba ery, insert the charging plug from the charger
into the ba ery charging jack on the back of the pump. Plug the charger
into a standard wall outlet. The PowerFlex Charger will fully recharge the
ba ery in ≤ 6 hours (see Accessories on page 28 for charger). Follow charger
instructions.

Using a non-approved charger voids the SKC
warranty.

Tampering with the battery pack voids the SKC
warranty and the UL Listing for intrinsic safety.

Do not charge or operate pump from charger in
hazardous locations.

Ensure that the computer interface port is
covered before and during charging.

Computer
Interface

Battery
Charging
Jack

Ensure proper orientation of charging cable before plugging it
into the charging jack. Improper orientation/contact will short­circuit the battery. See photo at right. Note the keyed side of the
charging cable plug must mate with the keyed side of the pump
charging jack. Inserting the plug does not take much force. If
force is required, the plug is not properly oriented.

Short-circuiting the battery pack will render it immediately
inoperative.

Battery Operation

Battery Charge Level Indicator

Three bars indicate a full charge (normally appears a er charging),
approximately 75 to 100%.

Two bars indicate that the ba ery is charged enough to operate the
pump, approximately 25 to 75%.

One bar indicates ba ery charge is low (charge ba ery), approximately
1 to 25%.

Low Battery Fault

No bars and a fl ashing outline indicate a Low Ba ery Fault (pump
will go into HOLD, and then SLEEP mode in 10 seconds). Run time
data can be displayed by pressing any bu on. The pump will return
to SLEEP in 10 seconds. This may be repeated.

When the pump stops due to a low ba ery and is le to stand for a
period of time, one ba ery bar may appear. This false “recovery” will
fall quickly if the pump is operated without recharging it. RECHARGE
THE PUMP BEFORE SAMPLING.

Replacing the Battery Pack

Ba ery Replacement Notes:

• To retain pump history, ensure the pump has been allowed to go to
SLEEP a er the last run. Pump history will be lost if the ba ery pack or
AC power (ba ery eliminator) is removed while the pump is running.
SKC recommends that data be downloaded to a PC using DataTrac 2000
So ware prior to removal of the ba ery or power.

• The fi rst 8 program steps will be retained in memory. Programs should
be reloaded using DataTrac 2000 So ware a er replacing the ba ery
pack.

1. Release the ba ery pack by removing the two security screws located on
the bo om of the ba ery pack. Pull the ba ery pack away from the pump
body.

of the pump base plate and push
the ba ery pack into place.

3. Replace and tighten the two
security screws removed in
Step 1.

Use of a repaired or rebuilt battery pack voids the SKC warranty and the
UL Listing for intrinsic safety.

Do not charge or operate the pump from the charger in hazardous
locations!

Use only an SKC-approved charger and battery pack designed for the
AirChek 2000 Sample Pump to ensure reliable performance and to
maintain the UL Listing for intrinsic safety and the SKC warranty.

Use of any device other than the approved battery pack to power the
pump voids the UL Listing for intrinsic safety.

Battery Eliminator

The Ba ery Eliminator is an accessory that converts alternating current (AC)
to direct current (DC) from which the pump can operate indefi nitely. The

Ba ery Eliminator should be used in non-hazardous locations only. See
page 28 for ordering.

To use the Ba ery Eliminator, the ba ery pack must be removed from the
pump (see Replacing the Ba ery Pack on page 5). The Ba ery Eliminator is
comprised of two pieces, (1) a wall cube that converts AC voltage to DC
voltage and (2) a power adapter that reduces DC voltage. The wall cube
fi ts into a standard wall outlet and its plug end is inserted into the power
adapter. The power adapter is fi  ed on the pump in place of the ba ery
pack.

Use the battery eliminator to operate the pump in non-hazardous
locations only.

Use of any device other than the approved battery pack to power
the pump voids the UL Listing for intrinsic safety.

Calibration

Flow Rate and Volume Display

Flow rate displayed on the pump LCD is the fl ow to which the
pump has been calibrated. To maintain fl ow as displayed, the
pump automatically adjusts fl ow during sampling for changes
in temperature and atmospheric pressure that may diff er from
the temperature and atmospheric pressure present at the time
of calibration. The fl ow rate display does not change from
the calibrated fl ow rate. The pump will fault if it is unable to
maintain the calibrated fl ow rate.

Volume displayed on the pump LCD is ”corrected” in that it
is the result of a continual calculation of corrected fl ow rate
multiplied by sample time.

Verifying Flow Rate Using a Primary Standard

1. Connect the pump inlet to the outlet of the representative sampling
medium using fl exible tubing.

To ensure sample integrity, tubing seals tightly onto the pump inlet
fi lter cover. Use care when removing tubing to prevent cracking or
breakage of the inlet fi lter cover.

2. Connect the inlet of the sampling media to a primary standard
calibrator using another length of fl exible tubing.

3. From HOLD, press [ST] to run the pump and enter ÒSTÒ within 10
seconds. You are in User Interface Level One. SET fl ashes on the LCD.

4. The LCD will display a fl ashing fl ow rate from the last sample taken. If
you do not wish to change the fl ow rate go to Step 6.

5. Press S to increase the fl ow rate or T to decrease the fl ow rate to the
desired se ing.

6. Press Ò. The fl ashing ADJ appears on the LCD, replacing the fl ashing
SET. The pump fl ow rate can now be calibrated using a primary
standard calibrator.

The fl ow rate displayed on the calibrator will change as a result of
this adjustment, not the fl ow rate displayed on the pump. The pump
will display an adjustment factor (ADJ) only.

7. Compare the fl ow rate from the primary standard to that displayed by
the pump. If the calibrator indicates a higher fl ow rate than the pump,
press T until the pump and calibrator are in agreement (within 10 ml).
If the calibrator indicates a lower fl ow rate than the pump, press S until
the pump and calibrator are in agreement (within 10 ml).

16

Calibration

8. Press Ò until End appears on the LCD. Press [ST] to save fl ow se ing
and exit the User Interface. The pump will remain in RUN. Reset run
time data (see page 12).

9. Place pump in HOLD by pressing [ST]. Disconnect the calibration
train.

Pressing [ST] will place a running pump in HOLD, and a holding
pump in RUN.

If a delayed start or DataTrac 2000 schedule has been programmed
into the pump, it may remain in pump memory. PROG will display
in the upper le corner of the pump display. To delete this program,
enter User Interface Level Two, scroll to the fl ashing OFF, and press

Calibration

Calibration Using the CalChek Automatic Calibration Feature

The CalChek automatic calibration feature is available when calibrating
an AirChek 2000 Pump with a Defender Calibrator (Cat. No. 717-510M). A
CalChek Communication Cable (Cat. No. 210-502) is required. Optional
DataTrac 2000 So ware can be used to expand the documentation capabilities
of this system. The CalChek feature provides two calibration options: single­point calibration allows se ing and verifying a fl ow rate at a single point
before and a er sampling. Multiple-point (full) calibration corrects fl ow to
a primary standard at multiple fl ow rates to cover the basic operational fl ow
range of the pump. Both types of calibration bring fl ow to within 5%.

If using a pump version below 2.59, a pump upgrade is required for the
CalChek feature. Contact SKC.

Do not perform single-point or multiple-point calibration until the
pump has remained at ambient temperature for several hours.

Single-point Calibration Using CalChek

The CalChek feature provides correction at a single fl ow se ing and takes
less than one minute to complete. Use it to set the desired fl ow rate before
sampling and to verify fl ow a er sampling.

1. Use 1/4-inch tubing to connect the Defender Calibrator suction port to the
inlet of a representative sampling medium and the outlet of the medium
to the AirChek 2000 pump inlet.

2. Run the pump for ≥ 2 minutes before starting calibration. Leave the
pump on.

3. Select the Defender data port:

a. Press and hold the Defender power bu on to turn on the calibrator.
b. Press the right arrow to highlight Setup; press Enter.
c. Press the right arrow to highlight Preferences; press Enter.
d. Press the down arrow to navigate to Data Port.
e. Press the le or right arrow to toggle to SKC.
f. Press the down arrow to highlight Confi rm; press Enter.

4. Enter Defender calibration mode:

a. Press the right arrow and then the down arrow to highlight Measure;

press Enter.

b. Press the right arrow to highlight Cont.; press Enter.

5. A ach the female end of the CalChek Communication Cable to the serial
port (RS-232) on the back of the Defender Calibrator.

18

Calibration

6. Insert the male end of the CalChek Communication Cable into the data
port on the pump.

7. Place the pump in HOLD by pressing [ST]. Press [ST] again to start
the pump running, and enter the security code ÒSTÒ in sequence on
the pump keypad within 10 seconds. You are in User Interface Level

One.

8. Press S or T to set the pump to the desired fl ow rate.

9. Press Ò on the pump keypad until CAL appears on the pump display.

10. Press [ST] to select single-point calibration.

11. 1CAL will appear on the pump display. During calibration, the pump
will display briefl y the fl ow rates that it is reading from the calibrator.

12. When calibration is complete, the pump display will either show End
indicating a successful calibration, or it will show an error code of E4[x]
(see CalChek Error Chart on page 22).

Note: To remove a CalChek error code from the LCD, press Ò.

13. Press [ST] twice to place the pump in HOLD. Disconnect the pump
from the representative sampling medium and the calibrator.

To ensure sample integrity, tubing seals tightly onto the pump inlet
fi lter cover. Use care when removing tubing to prevent cracking
or breakage of the inlet fi lter cover.

14. Allow pump to go to SLEEP.

Data does not write to memory until pump has gone into SLEEP
mode.

Successful single-point calibration will provide an entry in the pump
history that can be viewed using DataTrac 2000 So ware (v. 3.59 or
higher). If used with earlier DataTrac 2000 versions, the entry will appear
as an undecipherable code; update DataTrac 2000 So ware. If an error
occurs during calibration, the event will not be stored in history.

Calibration

Full (Multiple-point) Calibration Using CalChek

This type of calibration provides fl ow correction across the basic operating
range of the AirChek 2000 pump (750 to 3000 ml/min) in approximately
4 minutes. The operation calibrates each fl ow rate to a primary standard. It
can also provide a record of calibration for maintenance and quality purposes
if DataTrac 2000 So ware is used. SKC recommends that a full calibration be
performed during pump maintenance and a er non-factory repairs.

Full calibration clears history, run time parameters, and the
Scheduler in DataTrac 2000 Software.

Do NOT place sampling media in line for full calibration. Ensure the
battery pack is completely charged before starting a full calibration.

Do not perform single-point or multiple-point calibration until the
pump has remained at ambient temperature for several hours.

1. Use 1/4-inch tubing to connect the Defender Calibrator suction port to the
AirChek 2000 pump inlet. Do NOT place sample medium in line.

2. Run the pump for ≥ 2 minutes before starting calibration. Leave the

pump on.

3. Follow Steps 3 through 9 from Single-point Calibration Using CalChek on
pages 18 and 19.

4. Verify that the ba ery icon on the pump display shows at least two bars.
If it does not, charge the ba ery before proceeding.

5. Press S on the pump keypad 7 times to place pump in full calibration
mode.

6. The Defender Calibrator will begin to automatically calibrate the pump.
Initial fl ow measurements are taken without fl ow from the pump and the
pump fl ow rate is adjusted automatically. The pump will display FCAL,
CS1, and a brief fl ow rate. The pump will continue to display CS2, then
a fl ow rate, CS3, then a fl ow rate, etc. until calibration is completed at all
fl ow rates between 750 and 3000 ml/min.

Full calibration begins at fl ows lower than 750 ml/min. At these lower
fl ow rates, the calibrator piston will move slowly. This is normal; do

not interrupt calibration.

CalChek full calibration can be aborted by pressing [ST]. The pump
will go to HOLD.

20

Calibration

7. When calibration is completed, the pump will go to HOLD. If the
calibration was successful, the pump LCD will revert to displaying pump
run time as 0. If there was failure during the calibration process, an error
code of E4[x] will appear (see CalChek Error Chart on page 22).

Note: To remove a CalChek error code from the LCD, press Ò.

8. Allow the pump to go to SLEEP mode to write calibration data to pump
memory.

Data does not write to pump memory until pump has gone into
SLEEP mode.

CalChek Full Calibration Data

Full calibration data can be viewed and printed by going to the DataTrac
2000 Pump Manager window and clicking on the View menu. Choose
Calibration Info. This will display calibration results, pump serial number,
and date of the last full calibration. A bu on allows this data to be printed. The
printed report contains pump version, date printed, and a validation code.

CalChek Calibration Data Verifi cation in DataTrac 2000 Software

This feature requires pump version 2.62 or higher and DataTrac 2000
So ware version 3.62 or higher.

To ensure that printed data has not been tampered with, pull down the Tools
menu and choose Confi rm Validation Code. Enter the data from the printed
report, including the validation code. DataTrac 2000 will indicate whether the
information is completely valid or if a parameter has been changed.

Clearing the history will not clear full calibration data. This data can
only be cleared by performing another full calibration or by obtaining
more than 36 pump history records.

When entering data to confi rm the validation number, enter the date
in the following format: mmm dd, yyyy (e.g., Aug 18, 2008)

Calibrating for Low Flow (5 to 500 ml/min) Sampling
Applications Using a Constant Pressure Controller (CPC)

For use with CPC and Adjustable Low Flow Tube Holders.

The Constant Pressure Controller (CPC) is an accessory that allows low fl ow
(5 to 500 ml/min) applications. In conjunction with an Adjustable Low Flow
Tube Holder accessory, the CPC is used as a pressure regulator to maintain a
constant 20 inches water back pressure. See Accessories on page 28.

Calibrate with Adjustable Low Flow Holder, CPC, and representative
sample medium inline.

1. a. For single-tube applications, set the fl ow rate to 1500 ml/min.
b. For multiple-tube applications, the pump fl ow rate must be set at

≥ 15% higher than the sum of the fl ow rates through all tubes.

Do not exceed 500 ml/min fl ow rate per tube for multiple-tube sampling.

To set the pump fl ow rate, from HOLD press [ST] to run the pump

and enter ÒSTÒ within 10 seconds. You are in User Interface Level
One. SET and fl ow rate fl ash on the LCD.

2. The fl ow rate displayed is from the last sample taken. Press S to
increase fl ow and T to decrease the fl ow to the desired se ing. Press Ò
until End appears, and then press [ST] to save the change and exit the
User Interface. The pump will remain running. If desired, press [ST]
again to place the pump in HOLD.

3. Connect the pump inlet to the CPC outlet (the side of the CPC without a
label) using a short length of Tygon tubing.

4. Connect the inlet side of the CPC (marked “to sample”) to the
Adjustable Low Flow Holder.

5. Label tube(s) and port(s). Insert an opened representative tube into the
rubber sleeve of each port on the Adjustable Low Flow Holder. Place

unopened tubes in any unused ports to “seal” them.

6. Loosen the brass fl ow adjust screw on the low fl ow holder. Connect the
exposed end of one tube to a primary standard calibrator using another
length of tubing. From HOLD, press [ST] to run the pump.

7. Turn the fl ow adjustment screw (needle valve) on the low fl ow holder
until the calibrator indicates the desired fl ow rate.

The fl ow rate displayed on the calibrator will change as a result of
this adjustment. The fl ow rate on the pump LCD will remain at the
previously set fl ow rate, showing the fl ow rate through the pump, not
through the sample tube.

8. Repeat Steps 6 and 7 to calibrate the fl ow rate through each tube. Seal
unused ports during calibration with unopened tubes.

9. Place the pump in HOLD by pressing [ST]. Disconnect the calibration
train and replace the representative tube(s) with the tube(s) to be used
for sampling. Reset the run time data to zero (see page 12).

23

Sampling

Sampling (1000 to 3250 ml/min Constant Flow)

1. Following calibration, replace representative sampling medium with a

new unexposed medium. Ensure run time data has been reset (see page 12).

Protect sample pump from weather when in use outdoors.

For multiple-tube sampling, seal unused holder ports with unopened
tubes.

2. To begin sampling, press [ST] to run the pump. Record the start time.

3. Sample for the time specifi ed in the method used.

4. To stop sampling, press [ST] to place the pump in HOLD. Record the

stop time.

5. When sampling is complete, pump data is retained in memory for

recovery. Data can be viewed on the LCD by using the Ò bu on to scroll
through it or on a PC using DataTrac 2000 So ware.

When using impingers, place an in-line trap between the pump
and the impinger to protect the pump from harmful liquids or
vapors. Failure to use the impinger trap voids the pump warranty.

If a delayed start or DataTrac 2000 schedule has been programmed
into the pump, it may remain in pump memory. PROG will display
in the upper le corner of the pump display. To delete this program,
see page 14 or 15.

To ensure sample integrity, ensure tubing seals tightly onto the
pump inlet fi lter cover. Use care when removing tubing to prevent
cracking or breakage of the inlet fi lter cover.

Low Flow Sampling (5 to 500 ml/min Constant Pressure)

Low fl ow sampling requires a Constant Pressure Controller (CPC) and
adjustable fl ow tube holder available as accessories or in the Low Flow
Adapter Kit, Cat. No. 210-500.

When sampling with the CPC accessory and multiple tubes, the
volume displayed on the pump is no longer representative of the
volume of fl ow through the tubes due to the air bypass function of
the CPC.

1. Following calibration (see page 23), replace the representative tube(s) with

a new unexposed tube(s).

Protect sample pump from weather when in use outdoors.

2. Press [ST] to RUN the pump. Sample for the time specifi ed in the

method used.

3. To stop sampling, press [ST] to place the pump in HOLD.

24

Sampling

Long-duration Color Detector Tubes require a special tube cover
that accommodates an in-line trap tube. The trap tube protects the
pump from caustic fumes that are often released from detector
tubes. Closely read all precautions when using these tubes.
Failure to use the necessary traps will damage the pump and void
the warranty.

To ensure sample integrity, tubing fi ts tightly onto the pump inlet
fi lter cover. Use care when removing tubing to prevent cracking
or breakage of the inlet fi lter cover.

Use of any device other than the approved battery pack to power
the pump voids the UL Listing for intrinsic safety.

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 mode. During fl ow fault,
the pump HOLDs, the fault icon appears on the display during the length of
the fault, and the accumulated run time display is frozen and retained. As
part of the fl ow fault feature, the pump a empts to restart sampling a er fi ve
minutes in fl ow fault and continues to a empt a restart every fi ve minutes
therea er until the restricted fl ow is corrected or the pump has a empted a
maximum of 10 restarts. The maximum number of restart a empts may be
changed using DataTrac 2000 So ware.

25

Maintenance

Replacing the Inlet Port Housing and Filter

1. Remove the three screws that secure the inlet port housing to the
top of the pump.

2. Remove the inlet port housing and gasket.

3. Remove the O-ring.

4. Remove and discard the fi lter.

5. Insert a new fi lter (Replacement Cat. No. P40011).

6. Insert O-ring*. Replace the gasket.

7. Align the inlet port housing with the three screw holes and the LED.

8. Insert the three screws and tighten in an alternating fashion.
