50 InfiniiVision Oscilloscopes User’s Guide
The battery will last approximately 1.75 hours before requiring recharging. Operating time
depends on the oscilloscope configuration.
Operating with the Internal Battery
When operating with the internal battery, the operating temperature should be in the
range from -10C to 50C, 80% relative humidity. Low temperatures temporarily reduce
battery capacity.
1 Make sure battery is charged before use. See “Charging the Battery” below.
2 Connect the supplied ground wire from the ground post on the back of the instrument
to earth ground.
Caution indicator. Illuminates (amber) when running
on the internal battery. See “Operating with the Internal
Battery” below.
Battery power indicator. Turns from green to red when
there is 15 to 20 minutes of battery power remaining.
Charging indicator. Illuminates when the battery is
charging. Turns off when the battery is fully charged or
when the charger is disconnected.
WARNING
Maintain oscilloscope ground connection. Do not negate the protective action of
the ground connection to the oscilloscope. If the circuit under test has voltages
greater than 30 Vrms, the oscilloscope must be grounded through its AC power
cord (or its ground post on Option BAT models) to prevent electric shock to the
user.
