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.
Ensure proper orientation of charging cable before plugging it
into the charging jack. Improper orientation/contact will short-
circuit 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 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 flashing 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 first 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.

2. Carefully align the baery jack on
the replacement baery pack with
the baery terminal on the boom
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 indefinitely. 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
fits 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.

the temperature and atmospheric pressure present at the time
of calibration. The flow rate display does not change from
the calibrated flow rate. The pump will fault if it is unable to
maintain the calibrated flow rate.
Volume displayed on the pump LCD is ”corrected” in that it
is the result of a continual calculation of corrected flow 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 flexible tubing.
To ensure sample integrity, tubing seals tightly onto the pump inlet
filter cover. Use care when removing tubing to prevent cracking or
breakage of the inlet filter cover.
2. Connect the inlet of the sampling media to a primary standard
calibrator using another length of flexible tubing.
3. From HOLD, press [ST] to run the pump and enter ÒSTÒwithin 10
seconds. You are in User Interface Level One. SET flashes on the LCD.
4. The LCD will display a flashing flow rate from the last sample taken. If
you do not wish to change the flow rate go to Step 6.
5. Press Sto increase the flow rate or Tto decrease the flow rate to the
desired seing.
6. Press Ò. The flashing ADJ appears on the LCD, replacing the flashing
SET. The pump flow rate can now be calibrated using a primary
standard calibrator.
The flow rate displayed on the calibrator will change as a result of
this adjustment, not the flow rate displayed on the pump. The pump
will display an adjustment factor (ADJ) only.
7. Compare the flow rate from the primary standard to that displayed by
the pump. If the calibrator indicates a higher flow rate than the pump,
press Tuntil the pump and calibrator are in agreement (within 10 ml).
If the calibrator indicates a lower flow rate than the pump, press Suntil
the pump and calibrator are in agreement (within 10 ml).

8. Press Òuntil End appears on the LCD. Press [ST] to save flow 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 flashing OFF, and press
[ST].
