6.6 Reading-in Pulse Rates
For each calibration you have to read-in or enter count rates. In
this volume, there are several references to this procedure.
Read or Enter count rate?
The count rate can be read-in or entered.
Typically, the pulse rate is read in.
If the count rate has already been determined in the past, or in
another manner, then you can enter the count rate manually.
6.6.1 Procedure
Select READ and confirm the selection with OK.
READ means the current count rate is read in.
With
ENTER you can enter a pulse rate manually.
Reading-in count rates:
If necessary, change the value for the averaging time.
The standard value 0 selects an averaging time of 30 s, which
suffices in most cases. This means that the process is over after
30 seconds.
Enter a value >0 to determine another averaging time in sec-
onds. The longer this time, the more accurate the averaging.
Do not enter a number that is too high by mistake!
The process can be stopped only by turning off the Uni-Probe.
Start reading-in the pulse rate by clicking OK.
During averaging the level in the tank must not change. For agita-
tor vessels, the agitator must be running and a longer averaging
time, e.g. 300s, has to be used.
The count rate reading-in process has started.
If the process is started with “0” it takes 30s until the count
rate is read in. Otherwise, the duration of this process corre-
sponds to the averaging time entered.
