Note: The CBL can be used in
(without a calculator connected) to measure voltage, resistance, current,
period, frequency, meters, and feet without setup commands from the
calculator.
For example, pressing M O

In the display example to the right, these
batteries indicate a combined voltage level
of 4.50 Volts.
Note: This is the point at which a low-battery condition is sensed. In this
case, the batteries are low, and the low-battery indicator is on. The
optimum level is about 5.0 Volts with new batteries.
