Managing TPSBAT Battery Packs
Calibrating B
attery Packs
An uncalibrated battery pack cannot accurately report its remaining operating
time. The basic idea of calibration is to cycle the battery pack from a fully charged
state to a ful
ly discharged state, and then back to a fully charged state. This is
what the external charger does as part of the routine, and what the internal charge
method does step-by-step.
External Calibration
You ca n use
the optional TPSCHG battery charger to calibrate battery packs.
Appendix C includes information on optional accessories. (See Table 14 on
page 140.) For complete information, refer to the manual for the battery charger.
To calibrate batte ry packs, follow these steps:
1. Place th
e battery pack in the left-hand slot of the charger.
2. Push the blue and red s ymbol between the Push to Recalibrate Battery in
Left Ba
y label and the Energy Access Incorporated label.
3. After at least 3 minutes, check the LED status of the charger for errors.
The charger will charge, discharge, and then fully recharge the battery pack
returning it to a fully calibrated state. The calibration process can take up to ten
hours
to complete. Overnight calibration is recommended due to the slow nature
of the discharge-charge cycle.
Internal Calibration
If you do not have a TPSCHG battery charger, you can still calibrate a battery
pac
k inside the oscilloscope. To do so, follow these steps:
1. Power down the oscilloscope to allow a faster charge rate.
2. Apply external power from the oscilloscope AC adapter for approximately 5
hours per battery pack.
3. Remove the o scilloscope AC adapter.
4. Push the front panel power switch to power on the oscilloscope.
5. Operate the oscilloscope until it powers off, indicating the battery pack is fully
discharged (approximately 5.5 hours for 2-channel models and 4.5 hours for
4-channel models for each battery pack).
6. Again, apply external power from the oscilloscope AC adapter for
approximately 5 hours for each battery pack. During this time, do not power
on the oscilloscope.
If the battery pack is not fully charged and calibrated, attempt to calibrate the
battery pack again. If the second attempt fails, replace the battery pack.
