Instruction Manual
1.19 Configuration menu (cont.)
The ‘On Power Up’ (‘on.Pu’) menu configures functions to apply at start-up. It
applies only to instrument restart after power loss. It does not apply to instru
-
ment restart due to change in configuration.
• parameter ‘Delay’ (‘dLAy’) assigns a waiting time in seconds. The instrument
waits the configured time before starting normal function. During this waiting
time, the display shows all decimal points on in flash mode, all alarms are in
‘oFF’ state, there is no signal acquisition and there is no communications or
control being performed. After the configured time is over, the instrument
starts in normal function. Delay value between 0 and 200 seconds.
• the ‘Reset’ (‘rSt’) parameter will execute a reset of the counter each time the
instrument is restarted.
