Troubleshooting
Execute the I nitialize
Hardware function
There are multi
ple settings that can affect the operation of each channel. In the
event that it is unclear why a channel is not working, it is possible to restore
many settings back to a factory default state. The Initialize Hardware function is
intended for use only during the manufacturing and service of the instrument.
CAUTION. To prevent a loss of instrument configurationandadisruptionin
the output signals, do not p erform the Initialize Hardware function while the
instrument
is in service. Executing the Hardware Initialization function will
override many user settings. Only perform this function if you are sure it is
necessary.
When this function is activated, the CPU determines which hardware and software
options are installed and then configures the following system parameters to a
default state:
Enables all of the installed channels including the LTC channels if Option LTC
is installed
Arms all o f the installed BNC channels as switchover triggers (but not the
LTC channels if Option LTC is installed)
Sets all thresholds to the default values (NTSC for BNC channels, 2 V for
LTC channels if Option LTC is installed)
Disables the Relay Check function
Disables the SPG input trigger function
Sets the Startup Delay setting to 15 seconds
