Character data not allowed
HP-IB message = “No 
MINiMAX
 allowed while
checks are off”
Local message = “No MIN/MAX while checks are
off”
Description:
An attempt was made to set a parameter to 
MINIMAX
resp.
 to ask for the MIN/MAX of a parameter while
checks were switched off.
This does not work because other parameters on
which the 
MIN/MAX
 result depends might already be
outside no-warn range.

Local message = “No signal detected at 
CLK-INput”
Description:
An attempt was made to measure the external
clock frequency but no signal was detectable on the
clock-in connector.
Execution error

CLK-INput
 too
low. 
”
Local message = “Frequency at 
CLK-INput
 too
low. 
”
Description:
An attempt was made to measure the external clock
frequency but the detected signal frequency was too
low to allow an accurate measurement. (Currently
the limit is 1000 Hz.)
