Power Supply
The oscilloscope is supplied with one external power supply and set of
(6) 1.2 V NiMH rechargeable batteries 2700 mA·h.
When the supplied wall plug is connected from the instrument to an external
power source, battery power is not needed. The batteries are only used when
there is no external power supply available.
Before the first use, start by fully charging the battery.
NOTE:
The batteries automatically begin charging when the
Oscilloscope is powered off, but connected to an external power supply
When the batteries are charging, the Battery Charge LED on the front panel will
turn on steady.
The LED will blink in the following situations:
pre-charge of very low batteries
ƒ
temperature is too low or too high
ƒ
batteries are damaged
ƒ
When the charge is complete, the LED will turn off.
If the batteries need to be replaced, they must be replaced with NiMH
rechargeable batteries. Battery charge life is guaranteed for same-capacity
batteries (in mA·h) as those shipped with the oscilloscope.
To remove the battery cover, use a coin to turn the slot on the back of the unit
counter-clockwise.
