Displaying a Monitor Channel

Perform the procedure in Figure 2-12 to monitor an instrument analog channel (01
to 20) or computed channel (21 to 30). See Figure 2-13 for examples.
Channel Display When you press the MON key, the first monitor channel
displayed is the channel most recently monitored. After power-on, reset,
configuration, or self-test commands, the channel displayed is the lowest
numbered configured channel. When no channels are configured, monitoring
is not available. (Under this condition, an error beep occurs when you press
the Monitor key.)
Monitor Display The initial monitor display is a series of dashes, which lasts
for approximately one second. The measurement then appears in the primary
display (the secondary display shows the Global Channel Number). The MON
(monitor) annunciator is on when monitoring.
Monitor Reading Updates The instrument updates monitor readings once
per second. Since the 2640A measures readings with 5 ½ digits of resolution
and the display can only show 5 digits of resolution, the least significant digit
is truncated for 2640A monitor displays.

Press the MON (Monitor) key to monitor a channel. You can use Monitor
whether the instrument is scanning or not scanning.
Use the up/down arrow keys to select the desired channel. The instrument will
not allow selection of channels that are set to OFF.
Press the MON key again to exit.
