ITC AVOXimeter 4000 Operator’s Manual
Replacing the Battery
Materials Needed : 1. # 0 Phillips screwdriver
2. Diagonal cutting pliers
3. Replacement battery with cable (E4-BATP)
4. Securing cording (packaged with replacement battery)
1. Steps 1 through 11 of the Verification of Instrument Temperature
Materials Needed: 1. A thermometer that is calibrated and traceable to
National Institute of Standards and Technology (NIST)
standards (or other national standards). The
thermometer should be accurate to ±0.5 °C
2. Rubber bands or adhesive tape
2. Using rubber bands or adhesive tape, attach the bulb end of the thermometer to
the circular disk at the end of the ITC AVOXimeter 4000 temperature probe.
3. Ensure that the probe and the thermometer are in a thermally stable environment
and not in air currents.
4. Start the instrument.
5. Wait ten minutes.
6. Display the battery status screen (page 14).
7. Record the temperatures displayed on the battery status screen. Then read the
thermometer and record it as well.
8. If the ITC AVOXimeter 4000 temperature reading is within ± 3°C of the NIST
traceable thermometer, the ITC AVOXimeter 4000 is properly calibrated. If the
ITC AVOXimeter 4000
differs from the thermometer by more than 3°C, call ITC
Technical Support (800) 631-5945.
9. Cleaning the Optical Detector procedure on page 49 Must be performed before
moving to step 2 of “Replacing the Battery”, below.
Note: The battery is housed in the lower cover.
10. Using the diagonal cutting pliers, cut the plastic ties that secure the battery to the
frame.
Note: Be sure to cut only the white plastic ties that are wrapped around the
battery and secure it to the lower cover. Do not cut the blue and white
power cables that are connected to the top of the battery.
