Start, stop, measuring time, pause, delay
The measuring time is the time during which the memories for maximum, minimum
and mean value are open. The open state of the memories is indicated by "T" being
displayed. Before new measurements over the measuring time Tm are started, the
memories are cleared to enable the storing of new values. Whenever the measuring time Tm is ended, the result selected via the instrument configuration setting
"Sel.stat" is accepted into the statistics memory and the results selected via
"Sel.Prnt" are printed out.
The measuring time can be started and ended in three ways:
Manual
1. Manual control of the measuring time via Start/Stop
Press the key Konfig. on the rear of the instrument and select the
parameter
"STRT man".
The measuring time is started by simply pressing the START key
and ended whenever wanted by pressing the START key again.
Preset
2. Measurement over a certain preset period of time
Press the key Konfig. on the rear of the instrument and select the
parameter
"STRT Tm".
The measuring time starts after actuating the START key and ends
automatically after the preset time Tm.
For adjusting the measuring time (in seconds), set the parameter
"Tm [s]"
in the instrument configuration to a value in the range between 0.01 s
and 999.99 s by means of the keys
,
, or
.
Intervals
3. Given measuring time, cyclical repetition of measuring run (measurements in intervals)
Press the key Konfig. on the rear of the instrument and select the
parameter
"STRT Tp".
Pause
The measurement starts after having actuated the key START and
ends after the preset time Tm. After a pause time Tp, the measuring
run starts again. The cyclical repetition of the measuring time Tm
and the pause time Tp is ended on actuating the key START again.
The length of the pause "Tp [s]" is entered in the same way as the
measuring time Tm (0.01 ... 999.99 s).
Delay
By entering a delay time Td, between 0 and 99.99 seconds, the start
of the measurement will be delayed. Td is entered in the same way
as Tm.
Interruption
The measurement can be interrupted on actuating the keys
and
START and continued by actuating these keys again ( , START).
Adjusting the parameters Tm and Td is also necessary for the
measuring/reference function.
