Scaling converts actual measurement values to their corresponding values in arbi-
trarily determined units for display.This is convenient for converting the current values
provided by the logger for display as the corresponding physical values the sensor is
intended to measure.
For example, if a flow sensor provides a 4 to 20 mA output signal corresponding to 0
to 100 liters flow measurement, set as follows.
To specify by conversion examples
To specify by A/B slope values directly

Delete Data
Deletes recorded data in the selected logger
(only while connected).
Send PC Clock Time
Set the logger's clock to match the comput-
er's clock (after confirming the computer's

Slope = increase in scaled result ÷ increase in measured value
For the example case, (100 L - 0 L)÷(0.02 A - 0.004 A)=6250
