Understanding Modes

Communications Mode and Operating Conditions
When the CBL is on, it is in one of three operating modes:
Communications,
controls the mode.
Communications mode is the default operating mode for collecting data.
During Communications mode, the CBL is in one of three operating
conditions:
¦
READY
The unit is waiting for a trigger signal to start collecting data.
¦
SAMPLING
trigger condition has been met.
CBL is collecting data.
¦
DONE
indicates that data collection is complete. The data is now available
for retrieval by a calculator.
In the display example to the right, the
unit is in the Communications mode and is
sampling data from a motion detector
connected to the
Multimeter Mode
Important: Refer to "Safety Instructions" on page 4.
Note: Keys on the CBL are sensed differently from keys on a calculator.
Press and hold M and/or O until the command is recognized
when performing the operations described below.
From the Communications mode, M changes the CBL to the
Multimeter
through the multimeter operations: (
(±10 Volts), current, resistance, period, frequency, (ultrasonic) meters,
and feet.
