7-18 Scanning Model 2701 User’s Manual
Setting delay
As shown in Figure 7-1 and Figure 7-2, a delay (auto or manual) can be set by the user.
With auto delay selected, the delay period depends on function and range (Table 8-1).
With manual delay selected, the delay period can be set from 0 secs to 99 hrs, 99 mins,
99.999 secs.
Perform the following steps to set auto or manual delay:
1. With the instrument in the normal measurement display state, press SHIFT and
then DELAY.
2. Press or to display AUTO (auto delay) or MAN (manual delay) and press
ENTER.
3. If you selected MAN, yo77xxu will be prompted to set the delay in the hour/
minute/
second time format. Use the
, , , and keys to set the delay.
NOTE Pressing the AUTO key sets the manual delay to 0.001 sec.
4. With the desired manual delay displayed, press ENTER.
For remote programming, the TRIGer:DELay <NRf> and TRIGger:DELay:AUTO <b>
commands are used to set the delay. See Table 7-1 for details.
NOTE The delay for ratio and channel average can only be set using remote
programming (Table 5-3).
Monitor channel
While in the normal measurement state, a scan list channel can be used to monitor
readings. When a channel is selected to be the monitor, it will assume the setup of the scan
list channel.
NOTE If you change the setup while a monitor channel is closed, that setup will be
copied to that channel in the scan list.
When a scan is started, the first channel in the scan list will be briefly displayed. While the
scan is in progress, the display will only show the reading(s) for the monitor channel.
After the last channel is scanned, the scan will disable with the monitor channel closed.
Monitor can be used with limit testing to trigger the start of a scan. When the monitor
detects that a set reading limit has been reached, the scan is triggered to start. The detailed
procedure to perform a monitor scan is provided in “Scan operation — Monitor scan,”
page 7-35.
