Channel 2 Trace
Use the F3 and Range keys to reposition the channel 2 trace as follows:
• Short pushes of the F3 key moves the trace incrementally up.
• A long push of the F3 key places the trace at the midpoint of the scale.
• Short pushes of the Range key moves the trace incrementally down.
• A long push of the Range key places the trace at 10% of the scale.
Channel Selections
The channel selection mode allows you to switch the trace on and off. The F2 key controls the
channel 1 trace and the F3 key controls the channel 2 trace. Pressing the key the first time turns
this channel “off” and the sweep signal is removed from the display. Pressing the key a second
time puts this channel back onto the display. The previous characteristics for this channel are
saved during this process. The indicator at the base of the screen appears as inverse video (white
lettering on a black background) when a channel is on.

Bluetooth Discovery Selection
A special Bluetooth Discovery mode is available when operating in oscilloscope mode. Bluetooth
Discovery allows the M2 unit to be “paired” and connected to a host computer. This function is only
used when the VERDICT M2 has not been previously paired with a host, or if it becomes
necessary to pair with a new host. The VERDICT M2 can only be paired with one host at a time.
When Bluetooth Discovery is enabled, the VERDICT M2 seeks a compatible host computer, such
as the D7 Display Device. If a compatible device is within range, the VERDICT M2 recognizes its
presence, and can initiate pairing if so instructed by the operator. The pairing function requires
active participation of an operator. Once pairing has been established, the operator must exit from
the Bluetooth Discovery mode.
