Managing TPSBAT Battery Packs
Charging TPSB
AT Battery Packs
You can charge the battery packs in an oscilloscope or in the external battery
charger.
Charge method Amou nt of time to charge per battery
Oscilloscope (internal with the AC adapter) With the oscilloscope power ON, 7 hours
With the oscilloscope power on S TANDBY, 4.5 hours
External (TPSCHG)
3 hours
WARNING. Do not attempt to charge a battery pack below 0 °C (+32 °F) or above
+40 °C (+104 °F). Charging a battery pack outside of this range can damage
the battery pack and will result in a partial charge.
Interna
lCharge
The oscilloscope has a built-in charge system that can charge internal battery
packs while the A C adapter is connected. A fully discharged battery pack requires
approximately 4.5 hours to fully charge if the oscilloscope is powered down. If
the os
cilloscope is operating, a battery pack can take up to 7 hours t o fully charge.
If the oscilloscope has two battery packs installed, it will charge the battery pack
with
the highest available capacity first, until fully charged. It will then charge
the second battery pack.
Like
wise, if the oscilloscope has two battery packs installed, it will operate from
the battery pack with the lowest available capacity until it reaches full discharge.
The oscilloscope will then operate from the second battery pack until it reaches
full discharge.
To charge a battery pack in the oscilloscope, follow these steps:
1. Place the battery pack in the battery compartment. (See page 6, Battery
Packs.)
2. Apply external power from the oscilloscope AC adapter. The green, Battery
Charging indicator on the front panel lights and the battery pack begins to
charge immediately.
External Charge
You can use the optional TPSCHG battery charger to externally charge battery
packs. Appendix C includes information on optional accessories. (See Table 14
on page 140.)
To use the external charger, follow these steps:
1. Place up to two battery packs in the charger slots. Battery packs are keyed, so
you can insert them o nly one way.
2. The battery packs begin to charge immediately.
