The Front Panel Indicators at a Glance (Cont.)
Indicators Description of the Indicators
When this indicator flashes, it indicates that the Counter is
triggering on the input signal. If the input signal is too high,
this indicator remains ON. If the input signal is too low, this
indicator is OFF.
When one of these indicators is lit, it indicates that the
adjacent choice (that is, 50Ω, DC, X10, or 100kHz Filter) is
enabled or active. Note that when these indicators are not lit,
then the other choice (that is, 1MΩ, AC, X1, or no filter) is
active.
A lit Remote indicator indicates that the Counter is in
remote mode (Note: In the remote mode, the Save & Print
key becomes the Local key.)
If (while in remote) an error occurs, the Remote indicator
will flash. The indicator will continue flashing until the
controller has read or cleared the error queue, or until the
front panel returns to local mode.
An unlit Remote indicator indicates that the Counter is in
local mode.
The SRQ indicator indicates that the Counter has requested
service from the controller. The SRQ indicator will remain
lit until the controller has recognized the service request and
serial polled the Counter, or taken specific action to cancel
the request (for example, *CLS command).
